Box Push: Crate Puzzle

Box Push is a calm crate puzzle. Walk the worker around a small warehouse and push every crate onto a glowing goal. You can only push, one crate at a time, and you can never pull one back. That one rule is what makes each level a little knot to untie.

It plays like a classic sokoban game, the box push puzzle many of us first met on an old computer, but every level here is new. I wrote a generator and a solver for this app, and every level ships with the fewest pushes the solver could prove. When you finish, you'll see your moves and pushes next to the best possible count, as a gentle note and not a score to chase.

HOW TO PLAY
• Swipe anywhere on the board to take a step, and hold to keep walking
• Tap an empty floor cell and the worker walks there by the shortest way, without ever pushing a crate by surprise
• Prefer buttons? Turn on the direction pad
• Undo as often as you like, push by push, or restart the level

240 LEVELS IN FOUR PACKS
Warehouse starts with small rooms and two or three crates. Docks, Factory and Night shift grow to 12 by 12 rooms with up to six crates. Each 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 WARNING WHEN A CRATE IS STUCK
Push a crate into a corner it can never leave and the game tells you right away: this crate can't reach a goal anymore. One tap on Undo and you're back. No lives, no penalty, no timer.

EASY ON THE EYES
A dark 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 a reduced motion setting makes pieces jump instead.

ALSO INCLUDED
• Works offline, with no account and no sign in
• Your progress saves as you go, and a level you leave half done waits where you left it
• A short three step tutorial for your first run
• Sound and vibration you can switch off

If you enjoy a push box game, a warehouse puzzle or any logic puzzle where one careless move can trap you, this one's for you.
