A simple but challenging game. Flick the ball out and balance it on the tails of the two monkeys, then use the wheels at the side of the case to make the monkeys climb the tree and drop the ball into the home slot. The monkeys have to go at the same speed, though, or the ball will fall off, so what the person who was playing when this picture was taken was thinking is anyone's guess.
