About this game
Shuffles start from the solved board and apply hundreds of legal slides, so every layout can be finished. You win when tiles sit in order from 1 to 15 with the blank in the bottom-right corner. Press New Game or R for a fresh solvable mix.

Tips
- Solve the top row first, then the left column, before tackling the bottom-right block.
- Only tiles next to the blank move—plan a path for the empty space.
- Keep the last two rows flexible; cycle tiles around the blank instead of forcing one cell early.
