About Number Puzzle

Number Puzzle is the classic 15-puzzle: fifteen tiles and one gap on a 4×4 board. A tile may slide into the gap if it shares an edge. GameZumoza only presents shuffles that are solvable — some random arrangements never reach 1–15 in order, so the generator rejects those. Moves are counted. There is no timer pressure unless you impose it yourself.

How to Play Number Puzzle

  1. Press Play to shuffle a solvable board.
  2. Move a tile that sits next to the empty space into that space.
  3. Use taps, swipes, or arrow keys (arrows move the gap).
  4. Arrange tiles from 1 to 15, left to right, top to bottom, with the gap at the end.

Controls

Objective

Tips for Playing Number Puzzle

  • Solve row 1 completely before you touch the lower rows.
  • Place 4 only after 1–3 are set, then treat that row as frozen.
  • The last two rows are a small loop puzzle — do not panic-slide the whole board.
  • If a tile is in place, avoid moving it unless you are finishing the final rows.

Frequently Asked Questions

Why can’t I move a tile in the middle?

Only tiles adjacent to the empty space can slide. That is the whole rule.

Can a shuffle be impossible?

Not on GameZumoza. Impossible boards are discarded before play starts.

Does it work with a keyboard?

Yes. Arrow keys slide the gap, which is the same as moving a neighboring tile.
