Brimstone is the thirty-sixth level of More Bloons.
To complete this level, the most top Spiky Bloon should be popped, in order to make a chain reaction. Next, try popping the Tack Bloon on the right, using the Rubber Blocks. Note that the last part requires precise shooting.
- It is one of the few levels in More Bloons that requires all of the bloons to be popped.
