Rounds
Round 6
Round 6 in BTD6: 4 Green, 15 Red and 15 Blue Bloons, 57 RBE. The first round of Impoppable and CHIMPS, with opening advice.
Guide
Round 6 introduces the first Green Bloons: a quick group of 4 greens opens the round, followed by 15 reds and 15 blues. The total is only 57 RBE, but this is the round Impoppable and CHIMPS start on, so for many players it is the most important setup round in the game.
Greens take three hits and move faster than reds and blues, so the four at the front can slip past a single slow tower if it is placed badly.
Bloons in round 6
- 4 × Green Bloon (0.0s–1.7s)
- 15 × Red Bloon (5.3s–10.3s)
- 15 × Blue Bloon (10.8s–18.7s)
Total: 34 bloons worth 57 RBE. Popping everything pays $57, plus the $106 end-of-round bonus.
How to beat round 6
For normal games, whatever you placed earlier is already enough. For Impoppable and CHIMPS, round 6 is where your entire starting cash is spent, and a good opening carries you to round 20 or later.
- Place your hero first. It gains experience from the very first pop, so placing it on round 6 rather than later pays off for the whole game.
- Add one damage tower that will stay useful: a Dart Monkey, Ninja Monkey or a water tower such as a Monkey Sub on maps with water.
- In CHIMPS you cannot sell for full value or earn income, so avoid towers you plan to replace later.
The four greens at the start are the only part that can leak. Make sure your first tower sees the entrance.
Alternate Bloons Rounds
ABR round 6 doubles the opening greens to 8 and ends with 5 Regrow Green Bloons. Regrow bloons heal back to green if you only pop them partially, so place damage where they get hit several times in a row.
- 8 × Green Bloon (0.0s–3.0s)
- 10 × Blue Bloon (5.3s–10.3s)
- 5 × Regrow Green Bloon (10.8s–18.7s)
ABR total: 23 bloons, 59 RBE.
