🧩 15-Puzzle

The 15-Puzzle is the classic sliding-tile game. Tiles sit in a grid with one empty space — slide tiles into the gap until the numbers run in order.

How to play

1. Tap any tile in the same row or column as the gap to slide it across.
2. The puzzle is solved when tiles read 1 to 15 left-to-right, top-to-bottom.
3. Moves and time both count — plan ahead.

Difficulty affects grid size and time is your score — finish fast, post to the daily leaderboard, or race a friend.
