Round 51
Round 51 in BTD6: 15 Camo Ceramics and 10 Regrow Rainbows, 2,030 RBE. Bloons, the cash drop after round 50 and how to see camo ceramics.
Guide
Round 51 sends 15 Camo Ceramic Bloons spread over 18 seconds, followed by 10 Regrow Rainbows. The total is 2,030 RBE. It is also the first round with reduced cash per pop: from here to round 60, bloons pay half as much as before, which is why the cash shown below looks low for the RBE.
Camo ceramics are the first serious camo threat of the game. Every layer they release is also camo, so camo detection has to cover your strongest towers, not just a single support tower.
Bloons in round 51
- 15 × Camo Ceramic Bloon (0.0s–18.0s)
- 10 × Regrow Rainbow Bloon (19.0s–24.1s)
Total: 25 bloons worth 2,030 RBE. Popping everything pays $947.5, plus the $151 end-of-round bonus.
How to beat round 51
Pair ceramic damage with camo detection.
- A Monkey Village with 0-2-0 Radar Scanner placed next to your main damage is the standard answer, because it gives camo detection to everything nearby.
- Explosive towers crack the shells fast. A Mortar with 0-0-3 Signal Flare also strips camo from bloons it hits, which helps the rest of your defence.
- After the shells break, the rainbow, zebra and black children are camo too, so your sharp or magic pierce towers must also see camo.
- The regrow rainbows at the end need focused damage.
