Round 75
Round 75 in BTD6: 7 BFBs (two stacked triplets), 3 Fortified MOABs and 28 Leads. RBE, cash and how to beat it.
Guide
Round 75 is the first big BFB test of the 70s. It starts with a single BFB and a line of Leads, then sends a Fortified MOAB followed by three BFBs almost on top of each other. After a line of Fortified Leads, two more Fortified MOABs appear and the round ends with another triplet of stacked BFBs.
The stacked BFBs are what make this round dangerous. Three 700-health BFBs that arrive within a tenth of a second behave like one huge blimp, and when they pop they release 12 MOABs at once. The round is worth 25,402 RBE, pays about $2,492 from pops plus a $175 bonus and lasts only about 23 seconds.

How to beat round 75
You need high burst damage on blimps and something to deal with Leads.
- Burst BFB damage: MOAB Assassin's ability, Sticky Bomb ninjas, 2-5-0 Elite Snipers, a Plasma Accelerator or Ray of Doom, and Sun Avatar or Sun Temple supers are all strong choices.
- Area MOAB damage: the BFB triplets turn into 12 MOABs at once. MOAB SHREDR spikes, Ring of Fire or Inferno Ring tacks, and Rocket Storm Dartlings help here.
- Leads: most late-game towers already pop Lead. If you rely on sharp damage, add a Monkey Intelligence Bureau village (x-3-x) or a lead-popping tower.
- Stall: MOAB Glue or a Maim MOAB sniper slows the stacks down so your damage has time to work.
In CHIMPS, check that your MOAB damage covers the front half of the track. Letting the second triplet pass your first towers is the most common way to lose here.
