120 warehouse puzzle levels. Push every crate onto its target. Simple rules — deep strategy.
Free to start · One-time unlock for all 120 levels
Every level is filtered for "interestingness" — crates block each other, order matters, and the optimal path is never obvious.
60 classic levels run natively on Apple Watch — no iPhone required nearby. Swipe on the board to play.
Made a wrong move? Undo it. Experiment freely and learn the puzzle without restarting every time.
Crates glow red when pushed into an unsolvable corner — instant feedback so you know when to undo.
Full interface in English, Simplified Chinese, and Traditional Chinese — automatically chosen by your device.
No account. No tracking. No ads. Progress saves locally on your device and nowhere else.
iPhone and iPad get 60 high-difficulty levels (4–6 crates, 20–34 minimum pushes). Apple Watch gets its own 60-level track. All 120 levels are verified solvable by an A* algorithm solver.
