15 Puzzle

Slide tiles on a 4×4 grid to arrange numbers 1-15 in order from top-left!

How to play

Click a tile horizontally or vertically adjacent to the empty space — it slides into the gap. Arrange 1, 2, 3, 4 / 5, 6, 7, 8 / 9, 10, 11, 12 / 13, 14, 15 with the last cell empty. (See the 'Goal' mini-map.) Solve in as few moves as possible.
