In Cache-cache Souris ("Hide and Seek Mouse"), one player or team wants to move the cat Felix to catch the mouse Souricette, while the mouse player wants to keep it safe. They take turns placing cards on the playing area, gradually forming a labyrinth that sometimes opens a passage between the animals and sometimes throws an obstacle — a house, a cow, a scarecrow — onto the path. Will Felix find a way to the mouse? Will Souricette manage to hide until Felix tires out?
