Publisher statement The game is to locate all the letters of the alphabet in the correct order, beginning with 'A' and ending with 'Z'. It is also a "concentration" type game. The letters are placed randomly behind the different blocks. None of the blocks are marked. By pressing the arrow keys, you can move the crosshairs over a different block. To see the letter under the block, press the space bar.
