What is a sliding puzzle solver?
Most in-game slide puzzles use numbered tiles (1, 2, 3 …) and one blank. The starting order is shuffled randomly — yours will not match a friend’s, a YouTube walkthrough, or an old screenshot.
This tool takes the numbered layout you enter and computes a move sequence to the goal (usually 1→N with the blank bottom-right). Press Solve, then follow each slide with on-screen arrows — built for your scramble, not a generic one.
Ready to use
Open the solver and start immediately — no download, no account, and no upload. Everything runs locally in your browser, including heavy 5×5 searches on a Web Worker so the page stays responsive.
Step-by-step playback
Prev, Next, and Auto walk through each move with direction arrows on the board.
Custom goal state
Switch to Edit goal for picture puzzles or non-standard finished layouts.
Unsolvable detection
Impossible layouts are flagged before search — shuffle or fix tiles and try again.
Common use cases
Whenever a mini-game deals you a fresh numbered scramble — Palia, RuneScape, Brawl Stars events, or a plain 8-puzzle — copy what you see and solve that layout only.
8-puzzle & 15-puzzle
Classic 3×3 and 4×4 numbered slide puzzles in apps, toys, and browser games.
Palia mini-games
Copy your current board and set a custom goal if the finished picture is not the default tile order.
RuneScape (RS3) puzzle boxes
Larger grids and picture goals — arrange the goal state, then solve from your in-game scramble.
Brawl Stars event puzzles
Event boards are often random per player. Enter what you see instead of hunting a one-size-fits-all answer.
Escape rooms & brain teasers
Physical or digital sliding tile puzzles where trial-and-error would waste too much time.
5×5 and N×M boards
Switch to 5×5 or rectangular 3×4 / 4×5 when the mini-game uses a non-standard grid size.

Sliding puzzle solver FAQ
How do I enter my game’s numbered board?
Press Edit start, drag tiles to swap positions until the layout matches your scramble (blank included), then press Solve.
How do I solve a 3×3 sliding puzzle online?
Set size to 3×3, edit the board to match your 8-puzzle layout, then press Solve. Use Next or Auto to follow each move.
How many moves does a 4×4 / 15-puzzle take?
It depends on the scramble. Hard 4×4 sliding tile puzzles can need dozens of moves. This tool returns a working path quickly; it prioritizes a solvable sequence over a proven shortest path on larger boards.
Is this sliding puzzle solver free?
Yes. You can solve square and N×M boards in the browser at no cost, with no sign-up.
Can I set a custom goal state?
Yes. Switch to Edit goal to arrange the finished board (useful for picture puzzles in Palia or RuneScape), then Solve from your start layout.
Do you support non-square boards?
Yes. Choose 3×4 or 4×5 in the size pills, or stay on square 3×3 / 4×4 / 5×5.
Why does it say the layout cannot be solved?
Some arrangements are impossible under the sliding rules (inversion parity relative to the goal). Shuffle for a random solvable board, or swap tiles again to match a real in-game layout.
Can I use this for Palia, RuneScape, or Brawl Stars puzzles?
Yes if the mini-game is a sliding tile puzzle. Enter the current layout manually — layouts are often random per player, so there is rarely one fixed answer sheet.
Does Solve freeze the page on 5×5?
Solving runs in a Web Worker when the browser supports it, so the UI can stay responsive on larger boards.
