This is a simple 9 puzzle game. Shuffle pieces by tapping "shuffle" button. Then, a timer is activated to count elapsed time. You can swap a piece with an adjacent empty piece. Pieces adjacent to an empty piece are only movable.(adjacent to right, left, top, down). So, touch one of these pieces. "Game over" message will be shown when you restore pieces as they used to be. Take your time, and complete the mission!!
