50 Cards - 25 pairs matched by colors and shapes. Spread them across the table and grab the two dice, one for colors and one for shapes. Roll the dice and be the first player to slap both cards of the matching shape and color shown on the dice, then add them to your collection. Sounds easy enough, right?
Think you're ahead? Just wait! If the cards that match the dice aren't still in the middle of the table then they're around the edge, in somebody's collection. Other players collections still fair game! Protect your collection as you slap your opponents pairs away from them and into your collection.
