When the game begins, the tiles will be arranged in a certain way. All of the tiles behave the same way and are only differentiated by the pictures they have. Whenever you click on a tile, it moves into one of the available slots at the bottom of the screen. To make a match, you need to select three of the same tiles upon which they will disappear and be removed from the board. Depending on the removed, you'll gain access to other tiles beneath them. If you end up filling all of the slots at the bottom without making a match, you'll be locked out of a victory.
