Turnfall

Turnfall is a Sokoban — the classic box-pushing puzzle — with one new move: turn the whole bay and let gravity push for you.

Guide a small freight unit through 54 hand-built levels across eight warehouses. Push containers into their ports, then tip the room on its side and watch everything fall. Ballast too heavy to push, buoyant freight that falls upward, cryo crates that won't stop sliding, magnets, detectors and doors — each warehouse adds one new idea.

No timers, no lives, no ads, no account. Every level is proven solvable, undo is unlimited, and your progress saves in your browser.
