Sliding Puzzle

Classic 8-tile puzzle: slide pieces into the empty space until the numbers run 1 through 8 from top-left to bottom-right.

Tap a tile next to the gap to move it.

How to play

  • Only tiles orthogonal to the empty cell (up, down, left, or right) can slide—never diagonally.
  • Each tap swaps that neighbour with the empty space.
  • Goal: 1–3 on the top row, 4–6 on the middle, 7–8 on the bottom, with the gap at the bottom-right.
  • New puzzle reshuffles using only legal moves, so every layout stays solvable.

Game description

Snapshot. Eight numbered tiles share a tray with a single vacancy. You may only slide a tile into the gap when it sits orthogonally next door, which turns sorting into a slow-motion dance of legal moves.

Slide strategy.

  1. Anchor the top row before fighting the bottom chaos; partial order saves undo headaches.
  2. Picture moves as swapping the hole with a neighbor, not as teleporting numbers across the board.
  3. When you deadlock mentally, New puzzle generates another solvable mix without cheating physics.
  4. Compare move counts informally with a friend by passing the device after each shuffle.

Why play on fragox.com. Touch targets and the status line stay readable on small screens, so you can think in lines and corners instead of fighting the UI.

Patience under constraints. Planning three swaps ahead, noticing when you are cycling the same pair, and accepting a reset are quiet logic skills that transfer far beyond numbered squares.

Tips

Work row by row. If you get stuck, start a New puzzle.
