The box says "An Exciting 3 Dimensional Game." Aimed at children under eight years old. It is a race to see who can get through their 'cheese tunnel' first. Luck and colour recognition are all part of the race. The tiles are placed face down. Players draw a tile - If it matches their colour they can move their mouse along the tunnel. If it is not their colour, return it to the pack. There are penalties for drawing a cat card. The first player to get their mouse to the end of the cheese tunnel, wins.
