3 way

 is the thirty-first level of More Bloons.

Completion
To complete this level, all you have to do is pop the Spiky Bloons on the top, in order to destroy the Ceramic Blocks. Next, pop the Triple Dart Bloon above, and use the 3 darts to pop the Tack Bloons on all 3 parts.

Trivia

 * It is called "3 way" not because there are 3 solutions to this level. It is because there are 3 parts in the Metal Block structure, where each part contains 18 bloons, and in each part, there are 4 tack bloons, while 14 of them are normal bloons.
