Sliding Puzzle
Slide tiles into the empty space to sort 1–15.
The sliding tile puzzle dates back to the 1870s, when a version called the "15 Puzzle" swept the U.S. and Europe as a genuine craze. The appeal hasn't faded — it's a small, self-contained logic problem you can pick up and put down in seconds. Fewer moves means a cleaner solve, so once you've solved it a few times, try beating your own best count.
