Play the Sliding Puzzle free online. Slide numbered tiles into order on a 3×3, 4×4 or 5×5 board — the classic 15 puzzle, no install needed.
Tap a tile in the same row or column as the empty space to slide it. Order the numbers 1 upward to win. Arrow keys also work.
The Sliding Puzzle — known to many as the 15 Puzzle — is a pocket-sized classic that has fascinated players since the 1870s. The board is a grid of numbered tiles with one space left empty. By sliding tiles into that gap one at a time, you rearrange the whole board until the numbers run in order. Simple to grasp, surprisingly hard to master.
Pick your challenge before you start. Easy is a 3×3 board with eight tiles, a gentle warm-up. Medium is the famous 4×4 board with fifteen tiles. Hard steps up to a 5×5 board with twenty-four tiles, where every move needs to be planned. Tap any tile in the same row or column as the empty space and the whole line slides together — it still counts as a single move.
The game tracks your move count and your time, and remembers your best — fewest-move — solve for each board size. Tiles glow green the instant they reach their final home, so you can always see your progress at a glance. There is nothing to install and no sign-up — just open the page and start sliding.
Each solve is rated one to three stars based on how few moves you used, and pays out coins — more stars and bigger boards pay more. Spend the coins on the start menu to unlock tile themes like Sunset, Grape or Carbon; your coins and unlocked themes are saved in your browser.
Slide numbered tiles into the single empty space to rearrange them. The goal is to order the numbers 1 upward, row by row, leaving the empty space in the bottom-right corner.
Tap any tile in the same row or column as the empty space and it slides toward the gap. Tapping a far tile slides every tile between it and the gap as one move. You can also use the arrow keys or swipe.
They change the board size: Easy is 3×3 with 8 tiles, Medium is the classic 4×4 with 15 tiles and Hard is 5×5 with 24 tiles. A bigger board means more tiles and a longer solve.
Yes. Each board is scrambled by sliding tiles from a solved state, so a valid solution always exists. You can never get an impossible puzzle.
The game records the fewest moves you have used to solve each board size. Beating that move count is the main challenge — speed is tracked too, but the move count is the headline.
Yes. Your best move count for each board size is stored in your browser and shown in the top corner. Clearing your browser data resets it.
