General Information

Cash scaling

In later rounds, the cash per pop is reduced as follows:

  • Rounds 51-60: 50%
  • Rounds 61-85: 20%
  • Rounds 86-100: 10%
  • Rounds 101+: 2%

Blimp health scaling

Blimps get gradually more health per round after 80:

  • Rounds 81-100: +2% per round (1 + (round - 80) * 0.02)
  • Rounds 101-125: +5% per round (1.4 + (round - 100) * 0.05)
  • Rounds 126-150: +20% per round (2.8 + (round - 125) * 0.2)
  • Rounds 151+: +50% per round (7.5 + (round - 150) * 0.5)

Bloons in freeplay

A one-off change is made to regular (non-blimp) Bloons for rounds 81+:

  • All Bloons have only one child.
  • In exchange, ceramics are replaced by "superceramics" with 60 health (120 when fortified).
  • Superceramics also give an extra $86 when popped (scaled according to the round), which compensates exactly for the reduced number of children.
