Sokoban is the leanest logic puzzle ever designed: shove crates around a warehouse until every one sits on a target. You can push a crate but never pull it, and you can never push two at once. That single restriction is the whole game — the difficulty lives entirely in the order you choose.
Two packs ship with it. Starter is a twelve-puzzle ramp that introduces one idea at a time. Microban is the classic 155-puzzle set by David W. Skinner — small boards, one clean idea each, running from a single push all the way to The Dungeon. Arrow keys, WASD, an on-screen D-pad, and swipe all work. Undo is unlimited, Reset is one tap, and your best move count is saved per pack and level in localStorage.
