📖 How to Play
🎯
The Goal

Arrange all numbered tiles in order from 1 to N²−1, left to right, top to bottom, with the empty space in the bottom-right corner.


👆
Sliding Tiles

Tap any tile in the same row or column as the empty space. It — and every tile between it and the empty space — will slide over together.


🔀
