The game Memory with a theme. Three object cards are removed from the deck. The rest are mixed in with 12 clock cards and placed on spots on the board. Players take turns revealing two cards, hoping to form a match. When a clock card is turned over, it is added to the time row. When the 12th clock card is turned over, the game ends. At this point the players try to determine which three cards have been removed from the deck, based on the cards they have seen and the pairs that they have.
