Card game from the Dubbel en dwars series. All cards are printed on both sides. During the game you need both sides. In Lettermix everyone plays simultaneously. You try to play a card with a letter which matches (also in color) a letter of the top card of the discard pile. When you play a card with more equal letters, you may give a card to each other player. The first player that has played all his cards wins the game immediately.
