Each player in Top That! has five wooden bits before them: a black hat, orange tube, red goblet, green coin, and white rabbit. Shuffle the deck of sixty challenge cards, then reveal one of them. Players race to stack their pieces following two rules: Whichever pieces on the revealed card are in their original color must be visible in the stack. Whichever pieces are Shown in grey must be hidden somewhere within the stack. Whoever does this first claims the card, and whoever first claims a certain number of cards wins the game!
