How to Do the Regen Rainbow Rush

How to Do the Regen Rainbow Rush with the Ninja Monkey, Engineer Monkey and the Banana Farm

Note: Before the game, choose one cheap tower (ideally a Dart Monkey or Monkey Engineer), a Banana Farm, and a backup tower (we recommend the Monkey Apprentice or Ninja Monkey).

  1. Place Dart Monkey (or any other cheap monkey-like Engineer).
  2. Upgrade that monkey so it can handle the upcoming rounds (for the Dart Monkey, upgrade it to Triple Shot).
  3. Place a Banana Farm.
  4. Place another Banana Farm.
  5. Place a second cheap tower (like another Dart Monkey).
  6. Upgrade the tower you just placed.
  7. Upgrade the second Banana Farm to a Plantation.
  8. Place a third Banana Farm (Optional).
  9. On round 13 (or the end of round 12), sell all your Banana Farms.
  10. Send your opponent Regen Rainbow Bloons (make sure it’s the Rainbow Bloons with the number 3 on them).

How to Tell if Your Opponent is Planning a Rainbow Regen Rush

There are a few ways of recognizing if your opponent is planning to send you a Regen Rainbow Rush on round 13. These include:

  • Placing a cheap tower initially.
  • Placing Banana Farms early in the match.
  • They sell their Banana Farms on round 13 (or late round 12).

How to Defend Against the Regen Rainbow Rush

Note: These tactics are for the map Battle Park

When playing Bloons TD Battles, it’s crucial to know how to defend against the overpowered Rainbow Regen Rush because you’ll encounter it often.


When battling an opponent that seems to have intentions of rushing, investing in Banana Farms is the way to go. Because once you have survived their attempt at the Regen Rainbow Rush, you’re able to sell your Banana Farms and Regen Rainbow Rush. And with the cash gained from this, you’ll be able to rush them straight back.

Certain towers are very effective when defending against a Regen Rainbow Rush. These include the…

  • Tack Shooter
  • Ninja Sabotage (ability)
  • Engineer’s Bloon Trap (upgrade)
  • Mortar
  • Plutonium Reactor (submarine upgrade)

Note: The effectiveness of these towers varies from map to map.

Certain combinations of towers have a history of effectively defending against the Rainbow Regen Rush. There are:

Tack Shooter, Banana Farm/Cobra, Wizard:

Upgrade the tack shooter X-4 so you can get the Blade Maelstrom Ability. Place three 2-2 wizards which will all be boosted by the Cobra. The Cobra will deal with the Camo Bloons.

Tack Shooter, Banana Farm/Cobra, Mortar:

Blade Maelstrom (X-4 Tack Shooter) The Big One (4-X Mortar) and combined with Signal Flare (X-3 Mortar).

Dart Monkey, Banana Farm, and Monkey Ace:

Place many Spike-o-pults (3-X Dart Monkey) or Juggernauts (4-X Dart Monkey) facing down a line (To maximize their potential). Place many Super Monkey Fan Clubs(X-4 Dart Monkey) Around the Juggernauts. By using ODS (X-3 Monkey Ace) you can defend Camos, make sure to buy Ace Path Micro so that the Monkey Ace can hit as many bloons as possible.
