Guide

Round 72 mixes a steady stream of 38 Regrow Ceramics with two BFBs, one about 3 seconds in and the other about 16 seconds in. It is not a rush round, but it is the first time in a while that you face two 700-health BFBs, and each one breaks into four MOABs and then 16 Ceramics.

Regrow matters here. A Regrow Ceramic that gets chipped and then ignored will grow layers back, so towers that only tickle the stream waste their shots. The round is worth 10,280 RBE, pays $1,332 from pops plus a $172 bonus and lasts about 22 seconds.

Bloons in round 72

  • 38 × Ceramic Bloon (Regrow) (0–21.7 s)
  • 1 × BFB (at 3.4 s)
  • 1 × BFB (at 16.1 s)

How to beat round 72

Treat round 72 as a BFB check with ceramic support.

  • BFB damage: concentrated single-target damage is the priority. Elite Sniper, MOAB Assassin, Sticky Bomb, Sun Avatar or Plasma Accelerator Dartlings all handle one BFB at a time. A Maim MOAB sniper or MOAB Glue buys time if the first BFB gets close to the exit.
  • Follow-up: each BFB releases four MOABs at once, so make sure your MOAB damage is not all pointed at the very front of the track.
  • Regrow Ceramics: put area damage that kills Ceramics outright, not just strips a layer, in the path. Corrosive Glue or a Spike Factory near the exit is a cheap safety net.

In CHIMPS, spend the extra cash here on MOAB damage. Rounds 73, 75 and 77 all add more blimps, and the 70s only get harder.

Alternate Bloons Rounds

The Alternate Bloons Rounds version swaps the Regrow Ceramics for Fortified Ceramics and makes the second BFB Fortified (1,400 health). Total RBE is 12,320.

  • 38 × Ceramic Bloon (Fortified)
  • 1 × BFB
  • 1 × BFB (Fortified)

Frequently asked questions

What is in round 72 BTD6?

38 Regrow Ceramic bloons and 2 BFBs. The BFBs spawn at about 3 seconds and 16 seconds.

Why do Ceramics come back on round 72?

They are Regrow bloons. If you damage them without finishing them, they regrow layers, so you need towers that kill Ceramics quickly.

How much cash does round 72 give?

$1,332 from pops and a $172 end-of-round bonus.
