Round 81
Round 81 in BTD6: 17 BFBs, with 8 packed into the last 5 seconds. Freeplay ramping starts here. RBE, cash and how to beat it.
Guide
Round 81 is the first round after the Hard finish line and the first one where the game starts scaling bloons up. It sends 17 BFBs: nine spread over the first 20 seconds, then eight packed into about five seconds at the end.
Three things change from round 81 onwards. MOAB-class bloons gain health and speed every round (2% per round until 100), every Ceramic becomes a Super Ceramic with 60 health instead of 10, and regular bloons only release one child instead of two. That makes each BFB here 714 health and every MOAB it drops slightly tougher. The round is worth 44,506 RBE and pays $5,185 from pops plus a $181 bonus.
Bloons in round 81
- 9 × BFB (0–20 s)
- 8 × BFB (21.5–26.5 s)
How to beat round 81
This round is a straight BFB damage check, with the final group of eight being the real test.
- Single-target power: 2-5-0 Elite Snipers, MOAB Assassin or MOAB Eliminator bombs, Sticky Bomb ninjas, Plasma Accelerator Dartlings and Sun Temple all do well.
- Area MOAB damage: eight BFBs release 32 MOABs in a few seconds. MOAB SHREDR spikes, Rocket Storm, Inferno Ring and Glaive Lord style area damage stop those MOABs from walking past.
- Super Ceramics: each MOAB drops four Super Ceramics with 60 health. Towers that only did fine against regular Ceramics can struggle, so check your ceramic clean-up near where the BFBs die.
- Stall: Maim MOAB snipers and MOAB Glue slow the final rush so your damage keeps up.
In CHIMPS, round 81 is the first of the Impoppable-only rounds. Spend the round 79 and 80 cash on more MOAB damage, not on extra ceramic towers.
Alternate Bloons Rounds
The Alternate Bloons Rounds version sends 15 BFBs and 20 Fortified MOABs, for 57,670 RBE.
- 15 × BFB
- 20 × MOAB (Fortified)
