Switch/Strategies

Switch has relatively short paths and the paths open to the bloons varies.

Strategy #1
I recommend a Tack Tower someplace where you can get good range, but after that take speed over power. In addition, Spike Factories can't be that helpful on this track, so don't waste your money. A well-placed Monkey Apprentice can take you very far, but bear in mind that a poorly-placed one can defeat you very quickly. One very important tip: do not let too many bloons past the middle (cog).

alexmustcry's Strategy (Hard Difficulty)
I tried it. This doesn't work on easy mode!

1. Buy 2 boomerang throwers.

2. Buy 1 monkey apprentice and upgrade to 2/0.

3. Invest in 1 banana farm and alternately upgrade with your defenses until round 40.

4. Upgrade the monkey apprentice to 2/2.

5. Buy a monkey village.

6. Buy another monkey apprentice and upgrade both apprentices to 2/3

7. Buy 1 super monkey.

8. Upgrade the monkey village to 0/2.

9. Upgrade the super monkey to 0/2 ---> 2/2 ---> 2/3 respectively.

10. You could repeat step 9 or buy an ice tower and upgrade it to 3/0.

11. Use the remaining cash on buying Sniper Monkeys 4/2, Ninja Monkeys 0/4 (Bloon Sabotage), Glue Gunners 2/3 or Super Monkeys (2/3).

Notes:

-At rounds 24 and 33, don't hesitate to use road spikes on camos since the total cost for both rounds is at least $300.

-1 monkey apprentice with upgrades 2/3 is enough to make it out to many rounds before the appearance of ceramic bloons.

-By far, super monkeys with 2/3 upgrade is considered much cheaper and reliable than 3/2 upgrades since: upgrading a 2/2 super monkey into a robo monkey "doubles its power for only $8,000" other than upgrading it into a sun god "triples its power for $16,000".

-The previous point appears to be true, but isn't. The sun god shoots 3 shots at normal speed, each popping 15 bloons. The robo-plasma shoots 2 shots at double speed, each popping 5 bloons. This makes the Sun God better for ceramics and under, and the Robo-plasma for blimps, since its cheaper and deals 33% more damage to a singel target than the Sun God.

-Using the Bloon Sabotage ability effectively on a ZOMG is like activating M.I.B. Call to Arms ability on towers simultaneously.

-Rounds to seriously look out for are 63, 76, and 78 since this rounds spawns ceramics which is somehow a surprise to your defenses especially on hard difficulty. Try the Arctic Wind with MIB Village for infinite ceramic popping power. Or use 2 spectres or a sun god or two.

-On tight situations, before you buy/upgrade towers- be sure to have an extra cash for road spikes that can pop equivalent to your remaining lives or twice. (From $300=110 spikes to $600=220 spikes)
