Game introduction
What is Sliding Puzzle?
The Sliding Puzzle is the classic 15 puzzle: fifteen numbered tiles share a 4×4 board with one empty space. Tiles move into that space, and the challenge is to restore numerical order without lifting any piece.
Although each move is simple, moving one tile changes the route available to the others. Every shuffled board here is solvable, so patient planning will always lead to a finished grid.

A little help
Sliding Puzzle tips
Move tiles in small loops instead of chasing one tile directly.
Place the final two tiles of a row together; solving them independently can trap the last tile.
Preserve completed rows by keeping the empty space in the unsolved part of the board.
