She has to be quick and nimble, the mouse who wants to be the first to climb the peak of the cheese. The higher the players make it in a predetermined time, the more points they get. This requires a lot of skill, after all, with Sourisquick the ball inside the mouse must not roll through one of the cheese holes. The mouse navigates up and around these traps using two drawstrings, which players grasp at their ends and use to navigate the mouse. The choice of the ball - a larger one made of wood and a smaller one made of metal - and the set angle of inclination of the game board (three are possible) determine the level of difficulty.
