The legendary puzzle of fifteen tiles in a 4×4 frame. Slide the tiles and line up the numbers 1 to 15 in order.
The goal is to arrange the shuffled tiles in ascending order, leaving the empty square in the bottom-right corner. Just 4 steps to the solution.
The 4×4 frame holds 15 numbered tiles and one empty square that you can slide neighboring tiles into.
Click a tile next to the empty square and it slides into place. There are no long slides — you move one tile at a time.
Arrange the numbers left to right and top to bottom: 1–2–3–4 in the first row, and so on up to 15.
When every tile is in place and the empty square is in the corner, the puzzle is solved. Moves and time are recorded.
The Fifteen Puzzle is a single-player game of perfect information: there's no luck, everything comes down to logic and the order of your moves. The classic strategy is to build the board row by row and column by column, saving the bottom-right corner for last.
