In this game you need to put the monkey on the correct path so that it can take the banana. The monkey will follow the lines to move and will take a turn whenever it is possible, so you need to predict the path taken by the monkey in order to put it on the correct position. The less time you take to put the monkey, the more score you have.
This game is played by mouse only.
