A simple and enjoyable puzzle game. Swipe up, down, left, or right to move a tile into the blank space - no need to drag the tiles - swiping anywhere on the game board will make the tile move without having to fit your finger in a small tile. Before you know it, your bus / train / plane will be here, and the time just flew by while you played a relaxing, simple game. No ads. No in-app purchases. Just a game.
