In this tower defense style game, players place dart-throwing monkeys on the game map. The monkeys should be placed in a way that their attacks on a series of balloons trying to get by them are popped by the darts. As the levels progress, the balloons become faster and stronger. If the balloons make it to the exit, the players' lives are reduced by the number of balloons that exit unscathed. Players start with 40 lives, and those will quickly reduce if the monkeys are not positioned optimally.
