One thousand handcrafted Sokoban levels, ordered from first-push simple to late-game cruel. No energy timers. No paywalls. No daily quests. Just a warehouse, a goal, and a better move than the last one.
Start at 001, work forward at your pace. Unlimited undo, unlimited restart, progress saved locally without a sign-in. Difficulty is curved on purpose: the last two hundred actually fight back.
Random sequence, 60 seconds on the clock, +5 each time you solve one. Streaks rank on a global leaderboard. Optional rewarded-video revive if you want to chase the top.
