How to Play

The 15-puzzle consists of a 4ร—4 grid with 15 numbered tiles and one empty space. Click any tile adjacent to the empty space to slide it into that space. The goal is to arrange all tiles in numerical order (1โ€“15) left to right, top to bottom, with the empty space in the bottom-right corner. The Easy mode is solvable in around 20 moves. Hard mode requires a more strategic approach.
