15 Puzzle - Slide Number Game

🔢 The classic sliding number puzzle — also known as numpuz, sliding puzzle, barleybreak or the game of fifteen.

Slide the tiles one by one until the numbers are in order and the gap ends up in the corner. Easy to understand in three seconds, and still interesting after a hundred games.

🏅 EVERY BOARD SHOWS ITS MINIMUM
This is the part nobody else does. Before you make your first move, the game proves the shortest possible solution for that exact board and shows you the number. Your move counter sits right next to it, so you always know how close to perfect you are. Solve it in the minimum and you get three stars.

📐 FOUR BOARD SIZES
3×3, 4×4, 5×5 and 6×6. The 4×4 is the classic fifteen puzzle; the 6×6 is thirty-five tiles and a different animal entirely.

🖼️ PICTURE MODE
The same rules over a picture instead of numbers, with a preview of the finished image and the piece number on every tile, so you never get lost.

📅 DAILY CHALLENGE
A new board every day, the same one for everybody, with its minimum already proven. Keep the streak going.

👆 MADE FOR THE THUMB
Tap a tile and the whole row slides. Undo when your finger slips, ask for a hint when you are stuck.

⭐ RECORDS
Your record time and record ratio for each board size. The ratio is your moves divided by the minimum: 1.00× means you found the shortest solution there is.

✈️ OFFLINE AND LIGHT
No connection needed, ever. Small download, no accounts, no sign-up, nothing you did not ask for.

Every board this game deals has a solution. Half of all random tile arrangements are impossible to solve — this one never gives you one of those.
