For a game with only 9 blocks and a small deck of cards, Wonky is hours of fun. Each block has three curved sides, making them difficult to stack, but stack them you must. Players play cards on their opponents and those opponents must rise to the challenge and stack the chosen block, and if they succeed, they get to play a card of their own. Don't let the tower fall on your watch!
Wonky is a game for 2 or more amateur architects ages 8 and up.
