Froop!

On your turn, play a card from your hand onto the Froop, an amorphous pile of cards in the middle of the table, so that two symbols on your card match up with the symbols on the Froop beneath it. If you can cover 3 or 4 symbols, you immediately get another turn. The first player to run out of cards wins. Rules are included in 15 different languages, and advanced rules are included to make the game more strategic, faster, cutthroat, or all three.
