Bloons TD Battles/Strategies

Strategies requiring 50

 * 1. Strategy 1: (Ninja, Tack Shooter, Boomerang, Optional) First get a ninja upgrade it 3/2 then buy some tack shooters in convenient positions upgrade them 3/2.after get 4 boomerang monkeys upgrade them to 3/2 upgrade 2 2/3 then send in some ceramic bloons and fast bloons until you think your opponent is beat.
 * Strategy 2: (Buccaneer, Boomerang, Optional) This strategy is for levels with water. Start with a buccaneer and upgrade it to fast firing and long range as soon as possible. Get a boomerang thrower and get the bionic arm before getting any upgrades on the other path (after upgrading to bionic arm, you can do the other path.) Then get the destroyer upgrade on your buccaneer, buy another one, and upgrade this one to cannon ship. See if your apponent has defense against CLoDs. If they don't, send as many as possible at them. If they do, use RRoDs. If you still don't win, I would get more bionic arm boomerangers, but if you have a different favorite tower, then use whatever you want.

Strategies requiring 250

 * 1. Camownage: (Mortar, Tack Shooter, Spike Factory, Boomerang) Start off with a tack shooter in a corner, then get a boomerang ASAP. When you can, get a mortar and a factory. If the track is Cards, Temple, or Bloontonium Mine, aim the mortar at the spot where the two paths meet. If not, aim the mortar at where bloons spawned by your enemy come out. Upgrade the tack shooter to 3/2. Upgrade the boomer to 3/2. Upgrade the mortar to 2/3. Upgrade the factory to 2/2. Send out CLoDs, CoDs, RRoDs, and MoDs until your opponent dies.
 * 2. Aqua Camownage: (Mortar, Buccaneer, Spike Factory, Boomerang) Same as Camownage, but for levels with water. Use Cannon Ships instead of Tack Shooters. Once the threat of Camo Leads is over, sell the cannon ships and get destroyers.
 * 3. Dartling guns: (Ninja Monkey , Bomb Tower , Dartling gun, Boomerang ) Start off with a ninja monkey or a bomb tower, then make it 1/1. When you can afford a dartling gun place it at the center and make it 2/2. Then place boomerang throwers and upgrade them to 3/2. Keep placing dartling guns and making them 2/2. Whenever you feel like it send a bunch of regrowers or camos (Only in assult mode).
 * 4. Tack-tical Spikes: (Spike Factory, Tack Shooter, Bomb Tower, Optional) Start off with a Tack Shooter and make it 2/1, repeat 3 times. When you can afford a Spike Factory, place it in a loop, or near the spawn. At the end of the round, sell the Tack Shooters and upgrade your Spike Factory, keep upgrading until it is 3/2. Buy another Spike Factory and upgrade it to 3/2 again. Buy a Bomb Tower whenever you can and upgrade until 3/2, then buy another Bomb Tower, but this time upgragde it to 2/3. Now place as many 3/2 Spike Factories as you can. On round 30-40, or when your income is at least 3000, send as many Regen Grouped Rainbows X3 as you can. If your opponent still hasn't died, send heaps of Camo Regen Grouped Rainbows X3 until your opponent dies.
 * 5. Tack-tical Spikes ALT 1: '(Spike Factory, Tack Shooter, Bomb Tower, Optional) Same as Tack-tical Spikes, except instead of tack shooters at the start, instantly put the Bomb Tower, and upgrade to 3/2, then buy the Spike Factories. Continue on with the normal Tack-tical Spikes,without buying another 3/2 Bomb Tower. Continue on with normal Tack-tical spikes again, but instead of sending Rainbows, send a BFB or MOAB.
 * 6.  Tack/ Cannon Destruction(Tack Shooter, (Tier 4 unlocked,) Bomb Tower, Mortar Tower, Monkey Ace (Tier 4 unlocked.) Works on every map Except Zen Garden and Hydro Dam.)  Open with a 0/0 Bomb Tower ( On close), and then buy a 0/0 tack shooter. As soon as round 2 starts, spam grouped reds at your opponent, to get lots of income. Don't buy the 1/0 upgrade on the tack shooter right away, but buy it on round 3. Buy the 3/0 upgrade on the tack shooter by round 4. (Keep sending reds while doing this.) As round 4 hits, send grouped blues instead of grouped reds. Don't buy anything until round 6, in which you get a second tack shooter, upgraded 2/0. Start sending lots of grouped greens  against your opponent untill your income is 600. Then, save up your money ( To about 1000) And sell the 2/0 tack shooter and the 0/0 cannon and upgrade the 3/0 tack shooter to 4/2. Then, send grouped yellows to get economy up until round 10. ( Your economy should be around 750.) Buy a mortar tower, and upgrade it to 0/3, and then 2/3 before round 12. Buy a 3/0 tack shooter by round 13, ( Unless your opponent is extremly vulnerable to regrow rainbows, in which case finish him off,) and get another one up by round 15. Then, send grouped pinks up until mid round 16. (You should have 800 income.) Buy 2 2/3 moab maulers by round 18, to defend against any regrow moab rushes. (Put the maulers on strong). Keep sending grouped pinks up until round 20. ( You should have 1000 income) Get two more maulers, and save up for a 0/4 monkey ace. Send grouped pinks up until round 25. (You should have 1600 income), and save up your money. Unless your opponent has a ground zero,(In which case rush them with ZOMGs, on round 30,) Rush your opponent with Fast Cooldown Regorw BFBs, and put some Fast Cooldown Camo Ceramics under them if your opponent has a mortar as full camo detection on round 30.

Strategies requiring 500
Apprentice Upgrade it to 2/2 as fast as possible, and then get more if you can. Banana Farm Upgrade it to 3/0, or possibly 4/0 if you've unlocked it. Upgrade the second path last. Get another banana farm if you can. Simply hover your mouse over the bananas to collect it. Both Get the banana farm first. Upgrade it to 1/0, then get the apprentice. The apprentice should be upgraded to 2/2 before upgrading the banana farm again.
 * 1. March 8th 2013: (Boomerang Thrower, Bomb Tower (tier 4 unlocked), Village, Super Monkey) Start with a boomerang played bionic arm first, then buy Multi-Target and then Glaive Thrower (placement is extremely important!), then start sending in the highest grouped bloons until around middle of round 7. (450-700 income, but varies with map and opponent's strategy) If the placement is good, then you will never have to worry about bloons escaping. If you have income around 550+, get another 2/3 Boomerang Thrower, especially when you think they are prepping to rush you. If not, then get a 0/2 Monkey Village.(somewhere between round 10-12) This counters Camo Bloons. Then, get a second, or if you have money, get a third. For some reason, a 0/1 Monkey village doubles the popping power of glaive ricocchet, allowing a 3/2 boomerang thrower to pop twice the bloons (twice damage of two glaives)
 * 2. Sam Wang: (Spike Factory, Boomerang, Apprentice, Banana Farm) Start with a spike factory near the end, then upgrade it to 1/0 ASAP. After that place two boomerang throwers at the front, one upgraded to 3/2 and the other 2/3, with the 3/2 set to strong and 2/3 set to first. Upgrade your spike factory to 2/2 and if you can purchase an apprentice or a farm. If you can't do both then ignore the following.
 * 3. Strategy 7: (Boomerang, Apprentice, Ninja, Optional) Get a boomerang thrower and upgrade it to 2/3. Then get a monkey apprentice and upgrade it to 2/2. Then keep sending regen whites. If your opponent doesn't lose, get a ninja monkey and upgrade it to 3/2. Then sell it and send in a rainbow regen rush. If your opponent survives that, next time, don't send the whites and just get a little income, sell the ninja AND the apprentice and send $7,000 (or $8,000 if your lucky) of rainbow regens.
 * 4. For players 500+ playing players 500-: (Boomerang, Apprentice, Optional, Optional) Get 2 Glaive Riccochets and place near the end. Around round 7 or 8, sell them and buy a 2/2 Monkey Apprentice. Then continuously send a White Regen rush up to round 10. At 10 buy another 2/2 Apprentice and when you can, stop sending white regens and send zebra regen. Then enemy should die in round 12.
 * 5. Strategy 9: (Boomerang, Apprentice, Bomb Tower, Optional) Get the Boomerang Thrower 1/3. Send in pink bloons (spaced) until you get 300 income change. If your opponent retaliates back, put a Monkey Apprentice 1/2. If your opponent didn't send bloons back at you, buy it anyway. Save your money until you get Lighting strike, then send blacks until you unlock White Bloons, then send whites. Get about 400 income. Try to save enough for a Summon Whirlwind. Ignore all bloons you can send and focus on getting 2 wizards with 3/2. (You will get 2 wizards by the time round 15 is around, thats the time your opponent might send ceramics, so beware.) Buy a Boomerang tower 1/3 just like the start of the match. Buy 2 M.O.A.B. towers, then you pretty much should stack on bionic boomers, whirlwind wizards, and M.O.A.B maulers. Send in zebras as regulars for round 21. Your goal is to get a lot of income.
 * 6. Assualt mode only: (Glue Gunner, Boomerang, Bomb Tower(tier 4 unlocked), Monkey Village) This strategy is not recommended if you don't want to play for a while. Start out with your boomerang thrower and sent in group reds. Get a bionic boomer with glaives before they sent in blacks (pinks if you must). Carry on building up your income till you get around 500. Buy a glue gunner and try to have it so it catches opponents bloons and still gets normal round ones. If your too late you'll need to get monkey village by round 12 first. Upgrade the monkey village so it has camo detection (makesure it covers the bionic boomer and try to cover the glue gunner). Get a 3/2 boomerang thrower then a 3/2 glue gunner. Make sure your glue gunner has camo detection now. Build one 2/3 bomb tower before MOAB comes. Start building tonnes of bionic boomers and moab maulers. Once you feel you've got enough bomb towers then focus on bionic boomers. If you start to get really bored either camo regen ceramic rush your opponent or build up your income and sent in a ZOMG (if they have too good of defense then your best chance is just to keep regen rainbow rushing them). If you can not defeat your opponent just focus on defenses and wait till either one of you die out.
 * 7. Magic Camownage:  (Apprentice, Buccaneer/Tack Shooter, Spike Factory, Boomerang) Like Camownage, but use Dragon's Breath instead of Mortars.
 * 8. OP Outback Village Farmers with Cannons: (Boomerang, Bomb Tower, Banana Farm, Monkey Village) Start with boomerang somewhere mid map and upgrade 3/0 before sending red or blue bloons.  Keep sending bloons till you reach 270 money.  Now add another boomerang near the first one and upgrade to 2/0.  Start sending pink bloons until you reach 315 money.  At this point, if your opponent isn't assaulting you with pink bloons (if they DO, save to upgrade 2nd boomer to 1/3 first) save money for your first banana farm and upgrade to 1/0.  Now send black bloons till you're at 350 money.  If your you're not being pressured by your opponent you can get your second banana farm 1/0...otherwise get bomb tower 2/0 near your boomers, then banana farm 1/0.  Now save up for Monkey Village.  Place village within range of your three towers (your two boomers and bomb).  Upgrade your boomerangs to 3/2 and 2/3 respectively.  Now start sending yellows your opponent's way till you reach 400 money.  Upgrade your bomb tower to 3/0.  Now if you timed this right, you should be right at the start of round 12.  IMMEDIATELY sell both banana farms and upgrade your monkey village to 0/2 so your three towers can stop camo lead, or anything else they throw at you.  Send the killing blow with your own camo-lead OR if they have good defence for this keep barraging with zebra bloons to build up your money to 500.  By then you'll hit round 15 with about 2000 cash...finish them with a combo of 4 grouped zebras and immediately follow with 4 ceramic regen bloons.  By using fast grouped bloons to *hide* your high defence regens, they will slip through even with a very strong defense.
 * 9. Dragon's Farm: (Apprentice, Dartling Gun, Banana Plantation, Optional) This is a strategy for maps with reasonable space for the plantations. This strategy is generally used defensively but with the abundance of money made you should be able to kill them if wanted. Start off with an apprentice near front lines so his line of fire can take out multiple bloons at once and upgrade him to 1/0 instantly. Upgrade him to 2/0 ASAP. Then if your enemy doesn't seem to be rushing with bloons get a plantation, upgrade it to 1/0, and then get a dartling. If he does rush get a dartling first then get a plantation. From round 4 onwards you should be spamming with the pink bloons trying to increase income. Then black, then white. Only continue rushing with white bloons unless you're opponent can't defend a certain bloon past it and is dying. Get the plantation to 2/0 during this process and proceed to get another plantation and try to get it to the same level. Once you have your farm set up, continue rushing bloons and wait til you have enough to get a 2/3 apprentice. If you have trouble defending, upgrade to a 2/1 dartling before this. Stop rushing at a $400 income; the plantations will take care of the rest. Once you have a 2/3 apprentice simply save up for 2/3 dartling. If you're opponent can't stop them, just send a moab or camo ceramics and kill him. Else, continue getting 2/3 dartlings. If you get to round 25, get another plantation at 2/0. From this point on, you can either get a tempest (4/2) apprentice or continue getting more rocket (2/3) dartlings. I suggest the latter as it is far more effective on moabs.
 * 10. SW8573: (Boomerang Thrower, Bomb Tower, Monkey Ace, and either Mortar Tower or Monkey Village; works for all maps but Hydro Dam) One element this strategy depends on is Boomerang placement, whether it can loop around the track easily or not. Begin with a 0/0 Boomerang Thrower, and then a Bomb Tower as soon as the timer reaches 0:20 (slightly before Round 2 begins). Target priority can be adjusted for the Boomerang (to Last) depending on the map, while the Bomb should always be set to Close. Begin sending Red Bloons as soon as Round 2 begins. Without stopping the bloon-sending, slowly upgrade the Boomerang to 2/2. By Round 4, slow down the bloon-sending, continue sending either Grouped Reds, or Spaced Blues. Upgrade the Boomerang to 2/3; sell the Bomb Tower if necessary. Once the Bionic Boomer is purchased, begin sending Grouped Blues and Greens. If your income is not yet at $600, continue with Yellows until your income reaches $600. However, be careful on Round 8 in case of Regen bloons; you might like to halt your income at $550 for a 3/0 Boomerang.
 * If on Rally or Yin Yang, you might like to choose a Monkey Village for Camo detection. In this case, you should hold back on sending bloons and building towers. If the opponent is not rushing you with Camo Bloons on Round 12, continue to save your money. They would usually rush you on Round 12, or 13 - with Camos or Regens respectively. If Camos, build a 0/2 Village immediately; if Regens, build another 3/0 Boomerang immediately.
 * On other maps, you would like to build a 2/3 Mortar Tower as soon as possible, usually aiming near U-shaped bends and loops.
 * If your opponent has not rushed you, nor is their defence weak enough to die from a rush, purchase a 4/0 Bomb, followed by upgrading to 4/2 as soon as possible. Your next choice of tower, if their defence is solid enough to survive rushes, should be 2 2/3 Bombs, set to "Strong". At this point, you would like to conserve on sending bloons unless you are certain it will defeat the opponent. Towers should be built accordingly, with a 0/4 Monkey Ace being the emergency tower if your opponent rushes you with strong blimps such as BFBs or ZOMGs. At late-game rounds, you should aim to upgrade that Mortar (if used) to 2/4, and to purchase more 0/4 Monkey Aces and 2/4 Bombs, using abilities as necessary. Grouped Pinks should be your choice of bloons to send for increasing late-game income.
 * 11.'Explosive Results: (Bomb Tower , Mortar, Optional , Ice Tower ) Start off with a Mortar, upgrade to 3/2. Save up for another Mortar and place it next to the other Mortar. Upgrade the Mortar to 3/2, then repeat it until you have 4 Mortars.Buy a fifth Mortar, but this time, upgrade to 2/3. Place a Bomb Tower 2/3 for MOABs. Place an Ice Tower to try and cover the whole map, with atleast 1-2. You should out last your enemy, also, to get more money, send bloons.
 * Strategy 12: Rainbows Galore: (Boomerang Thrower, Bomb Tower, Mortar, Banana Farm, good for most maps) Start off with a Boomerang and upgrade it to 3/0 (if you think your enemy will rush you with group bloons) or 2/3 (if the enemy will resort to using spaced, yet fast ones like pink). This will take good care of any opponent's bloon rushes for now. Once you are done, place a Banana Farm anywhere on the corners (most recommended) or available spaces of the map (if you can't put it on the corners) and start gathering money to get a Boomerang taking the other path of the first Boomerang you placed. If you reach Round 6, the best advisable rush is to use a mix of Blacks and Pinks; this is highly effective as most players do not care to set their targets to ones that fit their playstyle and therefore confuses the defenses of your opponent. It will have done some considerable damage after (very little to none if your opponent is quite good at strategies). Else if your opponent is an Ice-Staller, wait for Round 8 and send in a mix of Regrow Whites and Pinks instead. After that, build a Bomb Tower and upgrade it to 0/3 if your opponent has survived the previous rush, else Mortars on 2/3 (at intersection of main bloons and opponent bloon paths, else inbetween 2 paths that are close enough to any bloon at both areas) if you think the upcoming rush will defeat your opponent. The important part comes here.
 * ​Start slowly building up money for the upcoming rush, more is better. You can first test your opponent's defenses by sending in one pack of non-regen Rainbows as early as possible. Your rush is more effecient, but it gives you a good look at the chances of your rush ending the game. Anywhere more than 5% is enough to probably end the game, closer to the path than that means your rush will attempt to pass through (does damage, but it doesn't end the game). If they get popped before they even appear on the map, chances are your rush won't work.
 * Wait for Round 15 while building your strength up. The rush is very costly, and at the same time, very time-costing. Wait for Round 15. Once you are there, BAM! Your rush is ready for attack. Check Regen and press SHIFT+9 and SHIFT+8 one after another. How easy the rainbows are popped turn it into multiple regen bloons, which shield the ceramics. Along with the ceramic's defenses, most of the rush will go through and end the battle. Take note that while this rush works on even the best strategies, there are some which does beat this strategy. BTD 5 has shown that not even a Super Monkey (below 3rd upgrade of any path) could keep up to the rush's power. If your enemy DOES survive the attack, your chances of winning is extremely diminished unless you can build up enough money for an enhanced rush of your own, whilst still including Regen Ceramics and Regen Rainbows.
 * 12. A Quick and Easy Death (Sniper Monkey, Boomerang Thrower, Super Monkey, Optional, Does not work for Hydro Dam or the one Swamp like track) Start off with a Sniper Monkey and upgrade it to Faster Firing as soon as possible. Afterwards, buy a Boomerang thrower and put it near the beginning of the stage. Make sure to upgrade it with SonicBoom and Red Hot Rangs as soon as possible, When round 2 starts, send either Blue or Red bloons, whichever you find better. When round 3 starts, upgrade the Sniper Monkey with Full Metal Jacket, and set its target to "Strong". At this round, you will most likely have enough for the Bionic Boomer. Get that, and the Glaive upgrade. Around this point, you'll most likely be unstoppable. But if things get too rough, put out a 3/x boomerang thrower. At round 8, summon several WRoDs until your opponent falls or forfeits. If neither, don't fret. Keep sending them until you get a finance of 500+. Wait until you can buy the Semi-Automatic Rifle. Make sure to get the Night Vision goggles on Round 12. You'll be hard to take down at this point. At this point, just keep your money building up from the finance. once you get 4000, time to put in the Super monkey, if you haven't killed your opponent already. Upgrade it to 2/3, and just send bloons after your opponent until he dies. If things get rough, just place down some more 2/3 Super monkeys. No big deal.
 * 13.  Engineer, Apprentice, Supermonkey, optional not recommended) (iOS) . Follow these steps exactly and you are likely to be winning all of your games on battles (Assault mode only). The engineer is for early game dominance, the mage for getting cammo's and leads and the Super for ultimate late game destruction!!!
 * 1. Start with 2 engineers. Depending on map place one at the bloon entrance and one at the end. (Not too close to the entrance/exit, but close enough to attack them as they come out).
 * Upgrade both with sentry guns only! (1/0) you should have $100, spend this to spam 4 red ballons. If they send bloons green or above you MAY need to get the '9 inch nails' (x/1) upgrade if you are in trouble. But dont go further than this, use energy  if you have to, early game is the hardest.
 * Spam the Grouped Red bloons until lvl 4, then spam the grouped blue bloons. (Hint: only ever send the bloons on the top, these are the spammable bloons which are released quickly, incresing you income.) Spam Grouped greens and yellows until you reach $500 income. DO NOT GO FURTHER! You can finish sending bloons with leftover money, so you have something like $515, but do NOT go to $600.
 * Once there place a mage in a good, central position with lots of access to bloons, prefferably on a corner or repating loop. Upgrade to 2/2.
 * Now for the engineer who is upfront, upgrade to 4/1 increased range is not needed as you want your traps as close to the entance as possible (for income). Empty bloon trap as often as possible!
 * Save up till you have $4000, Buy a super monkey and place it in the center of the map, good position (his range is great but dont upgrade it yet).
 * If you are having trouble with camo bloons upgrade the mage to a dragon's breath, 2/3. Summon tornado, 3/2, is not recommended!
 * After this, save and upgrade your Super monkey to 1/0.
 * Ugrade your Engineer to 4/1. You can make a new Engineer at the start and upgrade him instead, this will increase income because you will have 2 traps being used at the start.
 * Upgrade your Super Monkey to Plasma, 2/0, then simply wait until you can get 3/0 (Sun God). Once you get this, you can send Grouped Black ($150) bloons at them until you have $1000 income. If you are having trouble you can get super and epic range (0/1 and 0/2), but this will kill the bloons before they get to you traps, reducing you income. Get another Super Monkey, this time make him 2/3 (the Robo Monkey). This should give you everything you need to take on the MOAB waves which will come at around lvl 27. If you are stuggling, use an energy on large groups of BFBs.
 * This may sound crazy, but then save up until you have $100,000 for the Temple of the Monkey God upgrade (4/x), once you get this, you are unlikely to be beaten. If you like you can send more Grouped Black bloons ($150) to increase income to $2000. Once you have temple, you can make your income as large as you want and fill the map with Robo Monkeys and Technological terrors until there is no space to place anything. Have fun!
 * Notes: Weaknesses are any camo that the mage/engineers foam cant handle. Your mage will not have the fire uprage by lvl 12, so a really long, fast wave of camo pinks may kill you if you dont use an energy, if this happens consistently, upgrade your mage to fire before bloon trap, but then bloon trap asap after this. Only other weakness is a lvl 18 moab rush. If your opponent decides to be an annoyance and sends a blue moab, you super will not be upgraded and you may have a hard time. Use energy when it gets in range of ur super and flamemage. If he or she constantly moab rushes, then upgrade your super monkey Before you second bloon trap.


 * 14. Strategy 14_Tran Bach Nguyen (Magic Apprentice (Tier 4), Banana Farm, optional (Dartling Gun- Tier3), Supermonkey) : Start with a Apprentice and upgrade it to 2/2. Then put 3 Banana Farms and upgrade them to 1/0. After that put 2 more Apprentice monkeys and upgrade them to 2/2,3/2. Then upgrade all banana farms to 2/0. Later upgrade the 2 Apprentice monkeys to 2/3. Then if you have enough money upgrade one monkey Apprentice to 2/4. Put another Magic Apprentice and upgrade it to 2/3. Optional if you want you cand upgrade all to full than you can put 2 Dartling Guns and upgrade them to 3/2 and 2/3. Then do whatever you want. You cand give them MOABS because you don't need money per wave because you have 3 banana farms. Then optional place another towers, but it would be VERY GOOD if you have a Supermonkey upgraded to minimum 2/2.
 * 15. Could this possibly be the best Agressor strategy ever? (Wizard Monkey, Banana Farm, Opt., Opt.) Start by placing a Banana farm ASAP. Upgrade it to 1/0. Unless you're trying for the extra two medalions, let the bloons leak. At round two, place down a 1/0 Wizard Monkey. Do not send any bloons. Save up until you get 1200, then buy Lightning. Upgrade your farm to 2/0, then place down another farm, preferrably right next to the last one. Upgrade that farm to 2/0 as well. Place down another wizard monkey. It's recommended to upgrade one of them to 2/2, so you don't get spammed with CLoDs or CPoDs. After round 13, send a Non-camo RRoD storm after your opponent. They will most likely not survive the storm. If they do, upgrade your Wizards to 3/2, then the banana farms to 3/0, or maybe 3/2? Save up enough money to send a BFB rush against your opponent. They will not survive it.

Assault Strategy (IOS)

Tack Shooter,Monkey Apprentice,Heli Pilot

Does not include rushes sent

Start with a tack shooter, at 18 seconds you can get a tack sprayer. Send income to get 500 or so, and get a 0/1 mage if you start getting overwhelmed. Shortly after, get your mage to lightning and (perhaps after more income boosts) get your 3/0 tack up to 4/0. Return to increasing your Income. By round 15, you should have approx. 1000 income (use pinks or blacks for best results). At that point, buy a Heli Pilot and try to get it to 3/2, on Lock in place near the start, then get 16000-ish money (more eco on the way if you feel safe enough) sell your Wizard and get Apache Dartship, put on Pursuit. NOTE: if you don't have a 3/1-at-least pilot on round 18 then buy a few more tack shooters, up to 0-2/3. At 22, if you have not sucsessfully killed your opponent, buy more Dartships.

iOS strategies
1. RwT: IOS ONLY (Monkey Engineer, Spike Factory, Banana Farm, Does not work on Hydro Dam. ) iOS: ​Start with a Monkey Engineer. Upgrade it to 2/2. Then get another Monkey Engineer, Upgrade it to 2-2 or 3-2 if you have it. Then spam pinks. Then, the Banana Farms come in. Put three Banana Farms. Upgrade them to 2/1. Then, put 2 spike factories. Upgrade to 2/2. Then if the opponent has not put camo lead defenses, spam camo leads at round 12. Rainbows (regen or camo) will make the opponent lose some lives. If it goes too long, spawn a moab and keep putting 3/2 or 2/2 Monkey Engineers and 2/2 Spike Factories. Upgrade the Spike Factories to 3/2 and 2/3. Keep putting towers and spawing M.O.A.B's, B.F.B's, ceramics maybe a Z.O.M.G. Remember, spawn pinks and rainbows to increase income.

2.'''Anti-farm "aggressor" strategy. IOS ONLY (Monkey Engineer, Spike Factory, Heli Pilot)'''

IOS Start by placing a Monkey Engeneer near exit. Do not upgrade it untill round 2 begins (upgrade once time is 0:24). Necessary upgrade is 2/0, no need in 9-inch nails. At the same time send bloons. Start by grouped red and then as a new bloon type upgrades, but be careful, you may need to place another 1/0 engineer about round 6. And keep bloons swarming. Try to get your income to 650-700. Now it is aproximitely round 8. Get a heli pilot (1/2). Upgrade it 2/2. ASAP get a spike factory near the entrance of the opponent's sent bloons. Upgrade in 1/2 or 2/2 that is up to you. After that upgrade your heli to 3/2 or build 1/0 heli. Beware RRoD! You should be capable of taking down 6-7 grouped rainbows, no problem. Now continue raising income by sending pinks/blacks (fast cooldown) till round 17. Get a moab shreder spikes upgrade. Raise income again (till 1000-1100). Now get 4-5 3/1 heli pilots ASAP. Raise income and gradually upgrade your heli pilots to apache, no troubles after that. If you happen to get a 4th tower as dartling, after having 4 heli, build 2 2/3 dartlings, then switch heli to pursuit. By the way bloon denial system upgrade works a bit better then apache, thus priority to upgrading is dartling.

Playing the "Aggressor" - A Guide to Bloon-Spam
What is the "Aggressor"?


 * The Aggressor is a player who aims to eliminate the opponent as soon as possible, and have them be crippled by sending as many bloons as possible in order to try and get more bloons to leak and increase profit. Because of this, the Aggressor often sends out the bottom row of bloons to send, like spaced blues, pinks, blacks, etc., to gradually wear down a bad defense.
 * Or, if the Aggressor knows the opponent's four towers or knows the opponent's weakness later on, he/she will stockpile income quickly by sending out the top row of bloons to send, like grouped reds, blues, greens, yellows, etc., then stop sending bloons suddenly. This allows the Aggressor to build up a very large amount of income and money in such a short amount of time. After getting an adequate defense, the Aggressor will send out a giant all-out attack, which will usually knock off all of the opponent's 150 lives.
 * But if the Aggressor is not sending bloons, he/she will go Banana Farms. Throughout the game, the Aggressor will keep getting a defense that's just strong enough to withstand the bloons that are being send, by computer or by player. While the Aggressor is doing this, he/she will also upgrade their Banana Farms, and maybe send out the bottom row of bloons to send to overpower the opponent's defense if it's not strong enough. At rounds when the disired bloon sends become available (Often infamous bloon rushes on rounds 8, 10, 13, 15, 18, 20, 22, etc.) the Aggressor will sell his/hers Banana Farms, wether it be one or two of them or all of them. Then the Aggressor will send out a giant rush of all the infamous rushes we know now. (See a later section)

The Basics of playing the Aggressor

 * Starting out as the aggressor requires a tower which can take down compacted groups of bloons in a short amount of time, or a fast tower. A Boomerang Monkey of 3/2 or 2/3 is appropriate and both can be used for further effect. An x/2 Monkey Villiage is the most obvious way in order for the boomerangs to detect Camo-Leads, which will be covered in a further section, or any tower which can penetrate leads and detect camo bloons to do the same job, such as Cannon Ships or Flash Bomb Ninjas. As soon as bloons are available (Round 2), begin sending them, bottom row or top row depending on your playstyle, as this is an important part of being an aggressor. As the rounds progress, you unlock more bloons, which you should send those which increase your income even more. This will be vital in order to increase your income to a disired amount.

Compounding your Income

 * Compounding Income is a cycle which makes the Aggressor effective. You may notice that as you send more bloons, there is an "Income-Change" which is listed alongside the Bloon-Details. You will get the amount of money you have in your "Income Box" every 6 seconds. Once you send a bloon, your income will change accordingly. By sending bloons, this allows you to be able to get more money from your income, and allows you to send bloons, which allows you to have even more of an income increase, and thus the cycle continues. By Round 20, because of the cycle your original income may have quadrupled.

PRoDs, BRoDs, RYoDs, CLoDs, RRoDs, CoDs, etc.: Your Best Friends and Worst Enemies

 * If your opponent has a defence capable of holding off these bloons easily, it is best not to waste money on them.
 * As with every opponent, they will learn from their mistakes if they do get defeated by one of these rushes and improve over time.
 * Round 4: PRoD (Pink Rush of Doom): At the start of the game, abusing Pink Bloons can be devastating if your opponent has a bad defense, especially on short tracks like Hydro Dam and maybe Cards. Though if your opponent can hold off the pinks, try to mix the grouped blue bloons with the spaced pinks. A 3/0 Tack Shooter or a 2/1 Ninja Monkey will usually have the pinks just fly right through the entire track unscathed due to the limited popping power being wasted on all the blue bloons.
 * Round 6: BRoD (Black Rush of Doom): This rush involves spaced Black Bloons at the first opportunity. Depending on the track, blacks will either be a total devastation (Hydro Dam) or a circumstantial bloon at best. (Bloontonium Mine, Rally, etc.) Bomb Towers are a popular tower, and these black bloons will easily overrun them if they are alone with no other towers.. Like the PRoD, you can mix the blue bloons with the blacks to inflict massive damage if your opponent has the above mentioned towers, not greens as blacks move at the same speed as greens.
 * Don't do so if the opponent has a tower with lots of popping power combined with black popping power, such as a 3/0 Tack Shooter and a 3/0 Bomb Tower, or a 3/0 Bomb Tower and a correctly positioned x/2 Mortar Tower. These can also gradually damage badly-placed 2/3 boomerangs.
 * Round 8: RYoDs (Regrow Yellows of Doom), RBoDs (Regrow Blacks of Doom), and RWoDs (Regrow Whites of Doom) are available on this round. As you can tell, this is the first round with real rushes as now regrow bloons are unlocked and grouped yellows as well as spaced white bloons.
 * RYoDs are sent to quickly run through towers with low popping power. A 2/3 Boomerang Thrower by itself, regardless of placement, will get overrun by these. A single 2/2 Monkey Apprentice or a single 3/2 Ninja Monkey will also get overrun. A 3/0 Tack Shooter will also get overrun, though do be wary as some opponents upgrade the Tack Shooter to the Ring of Fire, which will pretty much decimate the rush as well as some later bloon rushes.
 * RBoDs are sent to overrun towers that are bunched up together. If your opponent has all of their towers on the upper half of the Temple Map, or if they have all of their towers at where the enterance and exit are on the Yin-Yang Map, these Regrow Blacks will soon regrow, and if your opponent has a weak defense, leak and cause great damage. Though don't do this if said towers are too powerful.
 * If your opponent has a black-popping tower, but the tower that pops grouped bloons (One 3/0 Bomb Tower, one 2/3 Boomerang, etc.) is too far away from the black-popping tower, then the blacks will regrow in between, putting more strain on the tower that pops grouped bloons.
 * A single 3/0 Boomerang Thrower will also get overrun by the regrow blacks, and to increase the potency of the attack, space them out (Send one group, send another group 2.5 seconds later, send one more 2.5 seconds later, and so on.).
 * Much like Rounds 4 and 6, you can mix the regrow blacks with regrow yellows, causing massive damage to your opponent if their defense is not sufficient.
 * A common killer is sending out a few groups of regrow blacks, then sending out many grouped yellows. What will happen is that the yellows will overlap the blacks, causing low-popping power towers to not be able to pop all the blacks, and if said tower is the only black-popping tower, then some of the regrow blacks, which may or may not have regrown, will go through the entire track unscathed.
 * Regrow Whites are very similar to Regrow Blacks: They are send to overrun a defense that has towers bunched up together. Except that Regrow Whites can be sent out four at a time unlike the regrow black's three, the White Bloons have a lower "cost per bloon", White Bloons are slightly faster than Black Bloons, and obviously they are immune to freezing, but vulnerable to explosions.
 * See everything the Regrow Blacks can overrun. The Regrow Whites and regrow Blacks are so alike the same towers mentioned above will get overrun. Except that Bomb Towers can already pop white bloons, so the 3/0 Tack Shooter and 3/0 Bomb Tower combination will not get overrun by the Regrow Whites.
 * Round 10: RPoDs (Regrow Pinks of Doom) and RLoDs (Regrow Leads of Doom). Regrow (Grouped) Pinks are just like Regrow Yellows, except that they are unlocked later, faster than yellows, and can overrun more towers, such as a single 2/1 Dartling Gun. Although usually Regrow Yellows get the job done just fine, a player can resort to the RPoD if they do not have enough money at the time Regrow Yellows are unlocked (Round 8).
 * Regrow Leads can overrun similar towers that can be overrun by Regrow Blacks (See above), except that Bomb Towers are at a lot more risk. Sharp objects can't pop the lead layer, and the Bomb Tower can't pop the black layer. Therefore, if the opponent has a Bomb Tower near the enterance where you send bloons and black-popping power in the very back, the Regrow Leads can easily overwhelm the opponent's defense. Remember that you can also send out regular lead bloons if your opponent does not have enough lead popping power, like a 0/0 Bomb Tower that could whiff.
 * Round 12: CLoDs (Camo-Leads of Doom) and RCoDs (Regrow Camos of Doom): Round 12 is a devastating round among players much like Round 8. You and your opponent will need to have full camo detection to survive these rushes that are unlocked on this round.
 * Camo-Leads are particularly devastating bloons which are available for you to send at this round. They are one of the hardest bloons to take down due to the relatively few towers that can pop both camo and lead bloons by themselves, and can be either a major threat to your enemy, or yourself if the enemy retaliates. Newer players are susceptible to falling victim to the Camo-Leads due to a lack of Camo-Detecting towers which can pop leads, and will lose quite slowly due to the lead bloon's slow speed. Each Camo Lead when leaked not popped at will will drop 23 lives off either side.
 * Regrow-Camos are also particuarly devastating, though they are less popular. You should send out these types of bloons for an all-out attack: Regrow-Camo Spaced Rainbows, Regrow-Camo Spaced Zebras, Regrow-Camo Grouped Blacks and Regrow-Camo Grouped Whites. Any of these bloons will overrun the opponent if they have bad camo detection. One 2/2 Monkey Apprentice or a 4/x Dart Monkey is not enough to fend off these rushes by themselves, and either of these towers will easily get overwhelmed due to the Regrow-Camos constantly regrowing. Although don't send these out if you opponent has a 0/2 Monkey Village or 2/3 Mortar Tower, and instead send out regular, non-camo regrows.
 * These may not be mentioned, but sending out lots of camo grouped greens, yellows, and pinks (Not regrow) can slide past certain towers. For example, a 2/2 or a 2/3 / 1/3 Sniper Monkey can't keep up with the constant stream of camo bloons by themselves. A Spike Factory, from any upgrade from 0/0 to 3/3, also can't keep up with the lots and lots of grouped camo bloons, espcecially when all the bloons are "layered". A low-upgraded Ninja Monkey (2/2 or less) can't do much at all to defend all the grouped camo pinks by himself, and lastly, a 2/3 Mortar Tower that's not well-placed will not be able to de-camoize all the camo pinks.
 * "Layering" bloons is defined as sending out slower bloons first (In above example, grouped camo greens/yellows), then sending out faster bloons (In above ex., grouped camo yellows/pinks). Because the faster bloons will catch up to the slower bloons, all of the bloons will stacked on top of each other, which makes a great killer for towers that can't handle grouped bloons well.
 * Round 13: RRoD (Rainbow Rush of Doom): At the infamous Round 13, you may want to send out as many grouped regrow rainbows to either obliterate your opponent or waste a lot of money due to the opponent's strong defense.
 * If your opponent is lagging very badly, even if they have a Sun God, Robo Monkey, or another very strong tower (Which they normally shouldn't have by round 13), it may not keep up with a constant spammage of these bloons due to the massive lag.
 * Obviously, if the opponent has a supercomputer or doesn't lag, the tower will pop the bloons just fine. Whole rainbows take 47 lives away. A cheaper alternative is to use the less effective regrow zebras, although much, much more regrow zebras can be sent out due to their low, $300 dollar cost, compared to Regrow (grouped) Rainbows' hefty $675 apiece. Some people may even send in a bunch of camo-regrow rainbows to opponents who have towers who can detect camo so badly that they will keep regrowing.
 * Round 15: CoDs (Ceramic [Bloon] of Doom): If your opponent didn't die after all of the above mentioned rushes, regrow ceramics may get the job done. If your opponent has slow-shooting towers, such as 3/x Bomb Towers or 3/x Boomerang Throwers, then the ceramics will either continue to the end with it's shell still intact (and drop 104 lives off your opponent each), or the ceramic's children will keep regrowing from the slow-shooting towers and most likely kill the opponent. Camo ceramics (Or camo regen ceramics) are also quite deadly if your opponent has bad camo detection, such as a single 2/2 Monkey Apprentice or a single 2/3 Monkey Buccaneer.
 * On rounds 18 and after, MOAB-Class bloons can be game-enders, although also Fast-Cooldown (FC) Ceramics.
 * FC Ceramics, when sent out in a ~$8,000 rush, can easily catch an opponent off guard, especially when they are preparing for MOABs. One, maybe two 2/3 Boomerangs with Two 3/0 or 3/2 Boomerangs can get overrun by these.
 * Specifically an early MOAB sent out right at the beginning of Round 18 against an unprepared opponent without 2/3 Bomb Towers, Super Monkeys, etc. If a weak MOAB defense is present, check regrow to give the ceramic-popping towers a harder time.
 * Round 20 unlocks the deadly BFB. This is what usually kills most opponents, specifically those who spend a lot of money to try to get two MOAB Maulers up by Round 18. A regrow BFB is even harder to defend, considering all the ceramics inside. Any sort of weak MOAB defense, one that can barely hold off one MOAB, will get easily overrun. Any setup without x/4 Bomb Towers, 3/x or x/3 or higher Super Monkeys, x/4 Monkey Aces, x/3+ Spike Factories, etc. will have a very hard time combating this.
 * Say your opponent has an anti-MOAB defense, such as MOAB mauler spam (About five or more). While a BFB costs less than four MOABs, it moves fairly slowly, and it gives your opponent much more time to react, save up money, micro-manage stuff such as selling-and-rebuying abilities, etc. To unleash a much more surprising and quick attack, consider sending Fast-Cooldown MOABs, which are also unlocked at round 20, in a group of at least five. If your opponent does happen to have five or more MOAB Maulers, then that means that most likely, there will be miniscule "bloon-popping" towers, like 2/3 Boomers and 3/x Bomb towers. The MOABs get popped and the ceramics will rush through, giving your opponent much less time to set up an x/4 Ace or an x/4 Tack Shooter. Though don't send these out if there is many bloon-popping towers on the opponent's side, as the ceramics will easily get popped.
 * Keep in mind that MOAB-Class Bloons will practically stop you from earning money as sending them all drain income (unless you use farms to gain income, which in that case 0 income change doesn't matter) and the B.F.B and the Z.O.M.G. are slow compared to M.O.A.Bs, giving the opponent an ample amount of time to set up a last-minte defense, such as a Ground Zero or an arsenal of MOAB Assassins. M.O.A.Bs are the weakest (and cheapest) MOAB-Class bloon though, so at the very least make the M.O.A.B. a regrow M.O.A.B. Regrow BFBs and ZOMGs are also quite deadly due to the mass amounts of regrow ceramics that come out of them.

Don't be Intimidated:

 * If the opponent sends out as many red or blue bloons that can be sent, or buys a particular tower in mass quantities, look at the opponents defense as a whole and concentrate on how to beat the opponent (Camo, Lead, Regrow Camo, MOABs, etc.). Also, if the opponent has the bloon decals, keep in mind that it does not affect the bloons he/she sends.

PRoDs, WRoDs, CLoDs, RRoDs, CoDs and MoDs: Defend Yourself

 * PRoD: These are very easy to defend against: Fast towers are recommended. Be careful when choosing, as only four towers are allowed and each tower counts. Boomerang Monkeys areparticularly popular, more specifically Bionic Boomer and Glaive Riccochet.
 * WRoDs: Regrow whites can look quite daunting, but all that is needed is a better defense. Lots of upgraded Dart Monkeys and maybe a powerful Bomb Tower can dispatch these. Once again, Boomerang Monkeys are used quite often to fend off these rushes, such as another Bionic Boomer/Glaive Riccochet.


 * CLoDs: These are harder to defend against. The most effective against this strategy is sufficient Camo detection, such as a 0/2 Village. A 1/2 Sniper Monkey is the Cheapest option to pop Camo Leads, and can be and is used by new and old users. The 1/2 Sniper will need extra towers to pop the Camo Lead's children however. Also, towers like 2/3 Ninjas and 2/2 Monkey Apprintices are fair, but the opponent can also mass a bunch of camo-pinks or camo-regrow rainbows to overrun them. The 2/3 mortar provides some camo detection, but it won't de-camoize all the bloons, and a (grouped) camo-pink rush will have many camo-pinks slide pass the mortar.
 * RRoD: 2-3 Glaive Riccochets or and a Bionic Boomer might just be able to beat a rainbow rush. Blade Maelstroms, 4/2 Bomb Towers work just as well.
 * CoDs: Juggernauts are good for lower level players as it deals extra damage to the Ceramic Bloon. If not, any tower that attacks fast will easily pop the ceramics. 4/2 Bomb Towers combined with a couple Boomerangs will also work. As for camo ceramics, a 2/3 mortar will not get every single camo ceramic de-camoized, but getting an additional 2/3 Mortar will fix that, or a 0/2 Village.
 * MoDs: Do whatever you'd do to defeat this in BTD5, for example MOAB maulers. Remember that MOAB-Class Bloons are unlocked quite quickly, one after another, so if you have enough income, consider some Technological Terrors or Ground Zeros, selling and quickly rebuying, using the ability each time.
