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

Eight numbered tiles share one tray with a single empty slot. You may only slide a tile into the gap when it sits next door along a row or column—never diagonally—so every shuffle is a walk through legal moves rather than a cheaty teleport. The goal is a classic ordered layout with the hole resting in the corner; reaching it is pure rearrangement logic.

New puzzle generates another solvable mess without leaving the page, so dead ends never strand you. Touch targets stay large enough that thumbs can nudge tiles without mis-taps, while mouse users enjoy the same clarity. Watching the blank square wander is the key insight: you are not dragging numbers across the universe, you are swapping the hole through the crowd. Skills sharpened here—planning three moves ahead, noticing when you are cycling the same pair, and resetting without shame—show up whenever you tighten a messy schedule or reorganize a list under constraints.

Tips

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