Rounds
Round 10
Round 10 in BTD6: 102 Blue Bloons, 204 RBE. The first big round, with cash earned and the best way to stop the late blue rush.
Guide
Round 10 is the first long round in the game. It sends 102 Blue Bloons in three groups over about 48 seconds: 60 spread out, then 20, then 22 packed into the last four seconds. The RBE jumps to 204, more than double round 9, and that final dense wave is where unprepared defences leak.
Bloons in round 10
- 60 × Blue Bloon (0.0s–35.0s)
- 20 × Blue Bloon (35.0s–44.0s)
- 22 × Blue Bloon (44.0s–48.0s)
Total: 102 bloons worth 204 RBE. Popping everything pays $204, plus the $110 end-of-round bonus.
How to beat round 10
The opening blues are easy. Plan for the last group.
- Pierce is the key stat. A Tack Shooter, a Dart Monkey with Sharp Shots or a hero with splash damage handles the final clump far better than a single-target tower.
- Place damage near the start of the track so the dense group gets thinned out before it reaches the exit.
- In CHIMPS, this is often the round where players buy a second core tower. It is also a good round to check how well your hero is levelling.
Round 10 also pays well because there are so many bloons. Spend the cash immediately on the next upgrade.
Alternate Bloons Rounds
The ABR version is 40 greens, the first 2 Lead Bloons of the mode and a closing group of 22 blues. Lead is immune to sharp damage, so darts and tacks cannot touch it. Bring something with explosive or fire damage, such as a Bomb Shooter, a Mortar Monkey or a Wizard Monkey with the 0-1-0 Fireball upgrade. A plain Wizard cannot pop lead.
- 40 × Green Bloon (0.0s–35.0s)
- 2 × Lead Bloon (35.0s–39.0s)
- 22 × Blue Bloon (40.2s–44.2s)
ABR total: 64 bloons, 210 RBE.
