Three variants of the classic 15 puzzle can be played:
1. Slide the tiles in a random sequence to a selected goal sequence.
2. Select a magic square sequence as a goal, i.e., whose rows, columns and diagonals sum to 34. The empty position contains a phantom 16 tile.
3. Take on a challenge puzzle and from a start sequence, reach the goal sequence in the minimum number of tile moves.
