Twenty48 is a new variation on the popular game app 2048. In this game, you stack up colored cards rather than sliding numbered tiles. Move your top card to one of the four free cells and start stacking them up in a sensible order. You can create long chains of cards, as long as you don't cross the dotted line at the bottom of the table. If you lay two identical cards on top of each other they will meld together, changing into a single card that combines the previous two values. You have a discard pile to get rid of cards you don't want to use, but think about it carefully, because you can only discard a total of two cards per game!
