Twenty48 is a fun version of 2048 but with cards instead of sliding tiles. Stack the cards on top of each other in the 4 empty slots. You can pile them up to make long chains, but you cannot cross the dotted line. Two identical cards will meld together and result in a card that combines the values of the two previous cards. If you get to 2048, those cards will vanish. Try to stack the cards in the right order. You have a discard pile, but you will have to use this option wisely since you can only discard a maximum of two cards in the course of a single game!
