About 15 Puzzle — 🧩 Sliding tile classic
The 4×4 sliding-tile puzzle. Numbers 1–15 in a 4×4 grid with one empty space. Slide tiles into order: 1 top-left, 15 bottom-right with empty space at end.
How to play 15 Puzzle
- Click a tile adjacent to the empty space to slide it.
- Goal: arrange tiles 1–15 in order.
- Always solvable — the shuffler only uses valid moves.
Tips & strategy
- Solve top row first, then left column, then continue in this L-pattern.
- For the last two tiles in each row, you may need to rotate the bottom corner.
- Don't move "solved" tiles away — work the empty space around them.
