Box Push: Crate Puzzle

How it plays

Swipe anywhere on the board to take a step, and hold to keep walking. Or tap an empty floor cell and the worker walks there by the shortest way, without ever pushing a crate by surprise. If you'd rather have buttons, turn on the direction pad.

If you played sokoban on an old computer, you already know the game. What's different is that every level here is new. I wrote a generator and a solver for this app, and the solver found the fewest pushes for each level before it shipped.

What's in the game

240 levels in four packs

Warehouse starts with two or three crates in a small room. Docks, Factory and Night shift add more, up to six crates in rooms as big as 12 by 12. A pack opens once you finish 20 levels of the one before it, and the levels inside a pack get harder as you go.

A daily puzzle

There's one daily puzzle, the same for everyone on the same date. Solve it each day to keep your streak going.

A note when a crate is stuck

Push a crate into a corner it can never leave and the game tells you right away. One tap on Undo and you're back. Undo is unlimited, push by push, and there are no lives and no timer.

Your pushes next to the best

When you finish a level you see your moves and pushes, and the best push count the solver found. It's a gentle note. Nobody's keeping score.

The night shift look

Blue walls, warm orange crates and cyan goal rings that close into a check when a crate lands. Moves slide smoothly, and with reduced motion on, pieces jump instead.
