15 Puzzle
One empty square, fifteen tiles. Slide the numbers into order and find room for your next move.
Walk behind a box and push it onto a target. You cannot pull it back, so plan the space you need to stand in before each push. These small warehouses offer a finite set of original puzzles without a timer.

SIMPLE TO START
Use the on-screen direction buttons, arrow keys, or W A S D. Tapping a square immediately beside the player takes one step. Z or Ctrl/Cmd+Z undoes. Moves count both walks and pushes; the push count is also shown separately.
Each level saves the player, boxes, move and push counts, and up to 200 undo steps separately in this browser. When browser storage is unavailable, switching levels still preserves progress for the current page session.
An independent implementation of classic box-pushing rules with original warehouse layouts, code and artwork by Puzzle Grove. Every starting position has a recorded and verified legal completion route. No third-party level catalog, game code, or branded artwork is copied. Routes are not claimed to be shortest, and level numbers are not calibrated difficulty ratings.
