Every player has one monkey. The monkey in the middle spins around. There are coconuts in the backpack of the monkey in the middle.
Players push the button under their monkey to hit the backpack. When a player hits the backpack at the right time a coconut will fall. But the monkey in the middle can suddenly change direction and hit your monkey with his club. Once hit, you fall out of your tree.
At the end of the game, the player with the most coconuts wins the game.
