A slide puzzle, also called a sliding puzzle, is a classic brain teaser in the wider family of sliding block puzzles. Rearrange tiles on a grid until they form a complete picture or the correct number sequence. There is exactly one empty space, and a tile can only move into that space.
A 3x3 number puzzle has 362,880 possible arrangements; exactly 181,440 can reach the goal. You can play for free right here: no downloads, sign-ups, or ads. Tap a tile next to the gap to start.
How to Play
Playing a slide puzzle is simple enough to learn in seconds:
- Look at the grid. You'll see numbered tiles with one empty square.
- Tap a tile next to the empty space. It slides into the gap.
- Keep moving until the numbers read 1 through 8 in order, or until the picture is complete.
- Watch the move counter and timer, then try to beat your best score.
Every new game is a fresh challenge. Tap Shuffle again to scramble the tiles, then race the clock.

Tips and Strategies for Beginners
Moving tiles at random can make the final few pieces feel tricky. These habits help:
- Finish the top row, then the left column. Keep those tiles in place while you rotate the remaining 2x2 area.
- Think two moves ahead. Before you tap, ask what position the move will create.
- Check the last two tiles. If they are the only two swapped in an otherwise finished board, no legal move sequence can fix it. A board made by this site's Shuffle button will never have that problem.
Stuck? Use the Solver
A 3x3 board that looks nearly finished can still take many moves. If you enter a board assembled by hand, it might even be impossible. Our free solver checks that first, then shows each move: a shortest path for 3x3 boards and a valid path for 4x4 boards.
A Puzzle with a Famous History
The 15 puzzle became a craze around 1880. One famous challenge put tiles 14 and 15 in each other's places while leaving the rest ordered. That board cannot be solved by sliding tiles. The puzzle still offers the same lesson today: a position can look almost complete yet be impossible to finish. ETH Library's 15 puzzle history explains the challenge.
Frequently Asked Questions
What is a slide puzzle?
A slide puzzle is played on a grid: move tiles into one empty space until the numbers or picture are in order. The game on this page is a 3x3 puzzle with eight tiles.
How do I solve a 3x3 slide puzzle?
Complete the top row, then place the left column without disturbing it. Rotate the remaining 2x2 area into place. If you want every move laid out, enter your board in the solver.
Is every slide puzzle solvable?
No. For the classic 3x3 numbered puzzle, exactly half of all arrangements are reachable from the goal. Shuffling by legal tile moves always creates a solvable board; swapping two pieces by hand changes that.
Can I play slide puzzle online for free?
Yes. Every puzzle on this page is free, requires no account, and works on phones, tablets, and computers.
Can the solver handle bigger puzzles?
Yes. The slide puzzle solver accepts 3x3 and 4x4 numbered boards and shows step-by-step moves. It returns a shortest path for 3x3 boards and a valid path for 4x4 boards.
Why is my slide puzzle stuck at the last two tiles?
Those tiles often need to travel around the board together. If they are the only two pieces swapped in an otherwise finished board, that arrangement is impossible to solve with legal moves. The solver checks which case you have.
