Select a skill level by clicking For Kids or Shanghai. The goal of the game is to remove all tiles from the screen. The rules are that you can only remove tiles by matching two that are the same, and they must not be blocked from sliding to the left or right. Click one tile, then click the second. If they match and they are free to be removed, they will disappear. You can only remove a tile if it does not have a tile on top of it, and it has a space free either to the left or right of it. Imagine sliding the tile out left or right. If there is a tile obstructing the one you wish to slide out, the move will be dissallowed. Good luck!
