Stop any Bloons from escaping the maze by building and upgrading bloons popping towers. Throw darts, tacks, bombs and ice. Can you make it through all 50 levels?
Game Instructions: Click on the tower type you want to build on the right side of the screen, then once its selected, place the tower in the maze.
