A Bonus Tower is a feature seen in Bloons Monkey City Mobile and Bloons TD Battles Mobile. It varies depending on game.

Bloons Monkey City MobileEdit

In Bloons Monkey City Mobile, a Bonus Tower is one free tower to use in a single game. It gives a random free tower to use for the one game. Once a random tower is selected, the Bonus Tower cannot be carried over to other games.

Bloons TD Battles MobileEdit

In Bloons TD Battles Mobile, a Bonus Tower is an extra slot for any random tower, even if the tower isn't fully unlocked yet. It costs Battle Energy1 to get a Bonus Tower, and it costs Battle Energy3 to re-roll the Bonus Tower.
