Red Bloon Equivalent (RBE)



Red Bloon Equivalent (RBE) is a new addition debuted in Bloons Tower Defense 4. It displays how many Red Bloons would need to be popped to equal the amount of pops it would take to clear the current stage. So, in the picture, fourteen pops are required to pass. It also appears in Bloons TD 4 Expansion and Bloons Tower Defense 5. In BTD4, it ranges from 11 through 2,881,114. A M.O.A.B's RBE is overestimated in the game as 613, but on Round 46, there is 1 M.O.A.B., and the actual RBE is 381. However, this may be due to the M.O.A.B. taking 200 hits to destroy.
