BTD6 Freeplay Mode/Strategies

This page contains strategies for Late Game and Freeplay Mode in Bloons Tower Defense 6.

Tips

 * Ezili is one of the best late game heroes due to her ability to deal percentage based damage to BADs. This means her powers ramps alongside the MOAB health.
 * Use of the Vengeful True Sun God or, at least, the True Sun God is a near necessity. Supplant it with Sun Temples or Dark Champions to make up the core DPS.
 * Saturate the core DPS towers with buffs. Make use of Alchemists and Homeland Defense to boost up towers often. Also, be sure to use Bloon Sabotage often for the continuous slowdown of all bloons.
 * Grand Saboteur is useful in doing a fixed percentage of damage to all blimps, especially to BADs.
 * Use the Support Chinook to move Permanent Brew Alchemists around to boost all your towers. Selling it will remove the boosts.
 * Reduce lag by using a few strong towers instead of spamming weak ones, preferably Sun Temples. Waiting until later rounds to place more towers is also an effective strategy.
 * The Super Brittle upgrade is often underestimated but it can increase damage to MOAB-class bloons massively. Place it around tight bends, similar to how a Tack Shooter would be optimally placed, and upgrade it to 5/2/0.
 * Cripple MOAB achieves a similar effect as Super Brittle as well. For maximum effectiveness, place it on one of the platforms of a Carrier Flagship and combine it with an Elite Sniper.
 * The Bloon Master Alchemist helps neuter ZOMGs regardless of round and health.
 * Stalling towers such as Superstorm and Icicle Impale help reduce the threat of fast blimps late game.
 * Make sure you are ready for clusters of Purple Bloons in the first 110 rounds as they come in stacks of 500+ with 0 spacing. They can be countered with a powerful tower such as the True Sun God or Glaive Lord.
 * Alternatively, fill the screen with Dark Champions due to their high damage-to-footprint ratio.
 * Use a 0/4/0 Ice Monkey and place the Super Monkey on the water part so it would be considered a water tower and can be applied more buffs
 * Make sure Vengeful True Sun God is unlocked and available to use. Even sacrificing being able to use Legend of the Night is more superior to ensure over 10x more overall DPS.
 * Always be sure to utilize Ultraboost, as it becomes super handy on super strong towers, especially to Vengeful True Sun God.
 * Admiral Brickell can boost your Vengeful True Sun God and other Sun Temples when they are placed on the water, effectively doubling your main firepower. Carrier Flagship can also boost your temples if they are on the water.
 * Alternatively, use Adora's Blood Sacrifice ability repeatedly to permanently double the attack speed of all Sun Temples and the True Sun God.
 * Freeplay Mode is usually the only viable choice for obtaining the Sapper, Bloon Master Populous, and Super BAD achievements due to the high amount of BADs, fortified bloons, and high HP MOABs in this mode.
 * The use of Pirate lord on the crosspath of 2/5/0 is a useful one, as the doubling of its already strong 3 cannons, as well as hot shot, make it great for shredding most bloons. this, combined with Energizer for its ability, can see you through many rounds leading up to round 100.

12.0+ Meta Strategy
This strategy is the main strategy that is widely used by many freeplay players and can achieve rounds higher than 500 on Logs. This strategy section is split into two sections, one for version 12.0 up to version 16.0, and another for version 17.0 and above. Due to a nerf for Unstable Concoction in version 17.0, the 12.0-16.0 strategy is rendered obsolete.

Additional Notes
Do note that your experience will vary based on the following versions:
 * On version 10.2 and below, the freeplay ramping was less dangerous than that of 11.0 and higher, and thus rounds above 3000 were possible to be achieved during these updates.
 * Version 11.0 has a bug with Obyn Greenfoot in which his buffs to magic towers hyperbuffed the Sun Avatars of VTSG, allowing rounds over 1000 to be achieved despite the freeplay buff.
 * Versions 12.0 and up patches the above Obyn bug, meaning that rounds around 600 is roughly the limit that can be achieved.
 * Version 13.0 allows saving of VTSG avatars, but they will end up being normal avatars with drastically reduced power. Be aware if you plan to leave later or if your game crashes.
 * This has been fixed as of version 14.3, and now correctly saves as VTSG avatars.

Also do note that if you plan to exit on higher levels, you must check your cooldown timings so you can be able to do a proper cold start. If you leave at the wrong time, it might be impossible to successfully cold start the round without using powers.

This strategy optionally uses 8 Tech Bots for AFK ability usages, and 1 Energizing Totem to boost your VTSG, totaling 480 plus additional MM for rebooting your Energizing Totem. You'll also need more MM if it becomes impossible to cold start a round.

Initial Build

 * 1) It is recommended to try the late game on a longer map with water such as on Easy Standard, such as on Logs, Cubism, or Carved. On Easy, bloon speed is decreased so you can achieve higher levels compared to on Medium or Hard. Bring either Admiral Brickell or Ezili as your hero.
 * 2) Quickly try to farm up to a VTSG. If you have no desire to use powers or instas at this early in the game, try getting Banana Farms to 2/0/0 then to 3/2/0. When you have enough money, get 4/2/0 Farms. Don't focus too much on farming though, you want to still survive the early rounds. Be sure to build Ezili or Brickell as soon as you can.
 * 3) Around your farms, build 0/4/1 Jungle's Bounty Druids. Jungle's Bounty will help boost your income quickly and also serves to help pop bloons.
 * 4) If you want to further boost your income, get a Monkey-Nomics bank to get money boosts and/or a Monkeyopolis to maximize farming with minimal space.
 * 5) Place an Arctic Wind near the water on the map and place a 3/2/0 Sun Avatar on the water. This will ensure that the VTSG can be boosted via Carrier Flagship, increasing attack speed. Be careful about camos, since Sun Avatar cannot detect camo with the path 2 crosspath, meaning you should have a Radar Scanner village ready.
 * 6) Sacrifice primary, military, and magic classes to the Avatar when upgrading to Sun Temple. If you need help on what you could sacrifice, sacrifice one MOAB Domination, one Apache Prime, and one Wizard Lord Phoenix. Once again, beware of camos.
 * 7) Place The Anti-Bloon and Legend of the Night outside of the Temple's range and sacrifice MOAB Domination, Apache Prime, Wizard Lord Phoenix, and XXXL Trap to the Sun Temple when upgrading to True Sun God. If you are successful, you should get the VTSG. Still, watch out for camos.
 * 8) Instantly after you get VTSG, place a 0/2/0 Radar Scanner Village with the VTSG in the range to ensure camo detection.
 * 9) Within the VTSG's range, get a Sun Temple 4/0/0 with just Support sacrifices. Sacrifice a Monkey Wall Street to accomplish this.
 * 10) Rebuild a 2/5/0 Homeland Defense within the range of both Temples so they can detect camo and have increased attack speed. Build two 1/4/0 M.I.B. Call to Arms to ensure full uptime of double attack speed.
 * 11) Build a 5/0/0 Flagship Carrier and 5/0/0 Energizer on the remaining water on the map. If you ran out of space to put water towers, place a Portable Lake on one of the map's corners and place the water towers there.
 * 12) Create a 5/0/1 Super Brittle within the range of most track coverage. Add a 5/0/2 Cripple MOAB and 0/5/0 Elite Sniper on the Flagship's carriers, with the Cripple MOAB set to Strong. Build a 2/5/0 Glue Storm outside of the track's range. They will serve to deal more damage to MOAB-Class bloons.
 * 13) Get a 0/5/0 Grand Saboteur and a 0/4/0 Bloon Sabotage outside of the track's range. This will help slow the bloons and within 3/4 of the uptime, reduce MOAB-Class health.
 * 14) Build an Ultraboost outside of the track range and attempt to overclock the VTSG ten times. Placing the Ultraboost on the track will allow it to shoot its Cleansing Foam and only add more lag to the game.
 * 15) *If you want, you can Ultraboost the Cripple MOAB and Super Brittle to make them apply the MOAB-weakening effect faster, which can be essential for later rounds with stun resistance.
 * 16) While you're overclocking towers, add a Permanent Brew within the range of the towers and the VTSG. It will boost your towers further. If necessary, use Support Chinook to move your Permanent Brew. Be sure to sell the Chinook when you're done to reduce lag.
 * 17) Sell all your remaining Farms and Jungle Bounty Druids. You won't need to gain any more additional money at this point and keeping Farms and Druids will just increase lag.
 * 18) Lastly, you will need to use at least 8 Tech Bots to help reduce how much time you need to interact with abilities and can potentially allow you to "away from keyboard" until your game crashes. This is when you need to do the following properly to ensure full ability uptime (it is recommended to make sure all abilities are up before continuing):
 * 19) *You can use Tech Bots on Ezili/Brickell, Glue Storm, and Ultraboost freely. Be sure that the Ultraboost has last boosted the VTSG to ensure it boosts the VTSG. Each time you reload, you have to unlink the Ultraboost and boost the VTSG again before relinking due to a bug that makes the tower ultraboost nothing when reloading a save.
 * 20) *Now, this is where you have to time it properly. Tech Bot the Homeland Defense and wait for its ability to wear out. When that happens, instantly Tech Bot a Call to Arms. When that Call to Arms wears off, Tech Bot the other Call to Arms.
 * 21) *Repeat above for the Sabotage Ninjas.
 * 22) If you want, you can add an Energizing Totem within the VTSG to buff it further, although be aware that you'll need to recharge it for 20 each 5 rounds if you do use it.
 * 23) If it becomes impossible to cold start a round, you'll need to use Monkey Boosts and/or Super Monkey Storms in attempt to hopefully beat the round and be able to start the ability cycle again. Alternatively, you can simply lose all of the lives and buy a Continue, refreshing the ability cooldowns.

12.0 to 16.0

 * 1) After adding the Ultraboost, add as much 1/3/0 Unstable Concoction Alchemists as you can and set most of them on Strong or First. Unstable Concoction will serve to deal massive amounts of damage to bloons when they explode, meaning that you'll want to have it pierce to as many MOAB-Class bloons as possible. Don't get too much unless you want your game to lag (about 10-20 is good enough), and don't get the Acid Pool crosspath unless you want your game to lag even more.

17.0 to present

 * 1) Before adding support towers like Villages and the like, build as much Sun Temples with primary, military, and magic sacrifices as space can provide, as Unstable Concoction no longer boosts its damage past r150, making it not as useful anymore than compared to brute forcing with Temples. Due to this, you might want to play on the Steam version, otherwise the game can be prone to crashing easily on mobile.
 * 2) Using Admiral Brickell provides a better benefit of having a full-uptime Homeland Defense, allowing your Temples to attack faster. Of course, this comes with the cost of lagging your game more, so as stated before, it is recommended to try this on the Steam version instead of the mobile version.
 * 3) Add some stalling towers like Bloon Crush to catch any stray bloons about to leak, especially D.D.T.s.

At this point, it only comes to the matter of whether to use powers after a cold start and to restart the game when it crashes. Good luck!

Mathbrush's Strategy
You can get an Vengeful True Sun God before round 100 with the following money strategy:
 * Use cash drops on round 1 of Easy to get a monkey bank.
 * Every time you cash out the monkey bank, double the number of banks you have.
 * Once you have tons of money, get a banana central and a monkey farmer.

This will help you earn the Vengeful True Sun God. Make sure to get an Avatar that has double support sacrifices, as this will let it boost other towers, which will become even more important as you go on.

Ultraboost and Perma-brew w/ Chinook will boost everyone. Bloon Master Alchemist and Pirate Lord can both instant-kill even fortified ZOMG's, no matter how far along in Freeplay you are. Getting an Energizer will make the Pirate Lord (and all other towers with abilities) activate even faster.

Okie's Strategy
You can get an Vengeful True Sun God on round 100 without using any powers on easy or medium difficulty. This strategy requires you to use Benjamin and proper positioning of the free dart monkey to quickly rush Benjamin + Banana Farm fast. Instead of upgrading your first banana farm to bank, upgrade to 2-0-0 and quickly build 5 more 2-0-0 farms. After that, you should have enough gold to upgrade three of them to 2-3-0 banks before round 40 (one of them you will upgrade at round 28, allowing you to collect $9500 gold before round 40). As for towers, before round 40. you simply need a way to deal with camo and lead. On a map with water, a Monkey Buccaneer 0-2-2 does that easily. At round 40, you handle the MOAB by upgrading it to 0-4-2, allowing you to easily survive to round 55 with your existing monkeys while spending all your money on farms. You want 10 to 12 monkey farms at 2-3-0, then you can easily afford a 2-5-0 once you collect them all. As for towers, focus on getting the super monkey upgrades.

Saflandres' Strategy
To start off, go in easy mode logs, we will be using brickell as our hero. For cash generation, we will be using a 5/2/0 banana farm and 5x 4/2/0 banana farms. At round 40, just go in a easy defense like a dart monkeys, alchemist and a sub, plus brickel. You should focus more on cash generation, if things are looking a little bit tough, just upgrade your towers, cash generation is still top priority. We just need a ton of cash for the towers we need later. The first true step is to place a 0/4/2 arctic wind near the water of the map so you can place the sun avatar on water, if there is not enough space, sell a tower in the water in order to place super monkey. This is where the VTSG will be, because the sun temple will absorb the arctic wind, it will be classified as a water tower and can be buffed with brickel and other towers. But for now, since the super monkey cannot hit camos, put down a 2/2/0 village. Cash generation is still priority, if you had met the requirements just wait for the cash. If you have the money, place a 2/0/5 and a 2/5/0 super monkey not in range of the sun avatar to get ready for the VTSG. To sacrifice, we need a 5/0/0 bomb tower a 0/0/5 dart monkey, a 5/0/0 heli pilot, a 5/0/0 bucaneer a 0/5/0 village, and a 5/0/0 alchemist, if you had followed the steps correctly, when you sacrifice, the arctic wind will also be sacrificed so the sun temple will be a water tower. I strongly recommend doing this in between rounds as the sun temple cannot hit camos. But now we need to save up a ton of cash for the next upgrades. As they are even more expensive than this one. This time also add a 5/0/0 wizard as well as the other towers used to sacrifice for the sun temple. Now if we upgrade it, we will have a max out VTSG, get super range and epic range after, as well as a village for camo detection. Get a 2/5/0 village and a 5/2/0 alchemist to boost the VTSG. If needed, use a 2/4/0 heli pilot to move the alchemist around to buff towers. Get pursuit for it as the downdraft can help us for camo regrow ceramic rushes. Than place four more sun temples, and sacrifice it with towers of each category more than 50,000 cash for the maximum potential, if you do not have enough money, selling the farms is still an option, money is not priority anymore, it is DPS. Also get epic range on the sun temples. Place a pool on the right of the VTSG so we can put a 5/0/0 sub and a 5/0/0 buccaneer to further buff the true sun god. Get a 5/2/0 sniper on the platforms of the buccaneer and a 2/5/0 sniper on the platform as well. The second sniper is used to buff the cripple Moab, but the extra money generation does not hurt. Than get some money and place two 1/4/0 villages next to the VTSG, this will ensure the full uptime of the attack speed boost from their abilities. Than get a 0/5/0 ninja and two 0/4/0 ninjas off in the corner as we will also get a full uptime of their abilities if we time it correctly (we will always be slowing down the bloons). Also put down a 0/5/0 glue monkey in the corner with the ninjas as their attacks are not important, only the abilities. After, place a 0/5/0 engineer to boost the other towers, prioritize with the highest dps. Another important monkey to get at this time is a 5/0/2 ice monkey as this guy makes bloons take more damage percentage base which is really good for scaling in the late game. Now that we have all the ability towers, we can set up some tech bots, use the tech bots freely on admiral brickel boost as well as the glue storm and the ultra boost, but for the village we have to time it. We will tech bot the villages, the 2/5/0 first, and when the cool down is 1/3 way, tech bot the second one and when the second one is 2/3 way, techbot the third, this way it will have a full uptime of tech bots. Do this the same for the ninjas. Also techbot the heli pilot so it will always be dropping cash and life crates. Place a 1/0/5 alchemist to deal with ZOMGS and lower, a 0/2/5 glue monkey to slowdown bloons, a 0/2/5 ice monkey, and a 5/2/0 bomb. It is optional to add a 5/0/1 Druid. other DPS towers that you might include are a 5/2/0 dartling gunner, a 2/5/0 dartling gunner and 0/3/1 alchemists for extra dps. Also place down a ton of 2/0/4 super monkeys as their damage to footprint ratio is incredible making it ideal for the late game. Also place down a lot of 4/2/0 snipers to stun bloons furthermore. A 0/2/5 mortar can also be used to decamo DDTs if you have the monkey knowledge, and remove fortification.
