15 Puzzle features grids with 9, 16, or 25 cells, offering varying levels of difficulty to suit players of all skill levels. Your objective is to arrange the numbered tiles in ascending order within the grid. For example, in a 4×4 grid, you'll need to arrange the numbers from 1 to 15.

The grid contains one empty cell that allows you to slide the adjacent tiles into the empty space. To move a tile, simply tap or click on it. If the tile is adjacent to the empty cell, it will slide into the empty space. On touch devices, you can also use sliding gestures to move the tiles in the desired direction. Continue sliding the tiles strategically until you've successfully arranged them in the correct order, ensuring the empty cell ends up in the bottom right corner.
