Here we see one level of a three-level maze. Move from one adjacent stone to the next, travel through the yellow, orange, or blue tubes to another spot, or move up a level with the blue arrows.

As a card with a hidden picture appears in the top bar, a voice names the letter of the alphabet which is hidden on that card. Once you place the card in the grid below, its picture, a sign language representation of that letter, is revealed. The object is to match two (or more) of the same letters horizontally or vertically. When you do, they disappear.
