Think of the classic game Tetris but with letters! Letris 2 is a fantastic game that requires its users to build as many words as possible, in order to keep the screen clear and tidy. The iPad version has a great split screen feature, allowing multiplayer modes. The WordMatrix mode is also available, which works in the opposite way to Letris. It presents users with a complete grid of letters, where words can be formed and then removed until all the tiles are gone!
