With Grimaffen, players can now make themselves a monkey: Each round dice the players with a special cube to find out from which category they need to uncover a plate. This must be imitated. They gesticulate with arms or hands, imitate animals or everyday objects and cut grimess. The plate is then reversed again. The next player must now repeat all previously revealed plates in the correct order before revealing a new plate. Players who make a mistake are different. Whoever remains last wins!
