LumenCrate

A depot runs on one steel schedule board. Half-hour slots across the top, a lane for every crew member down the side, and a night shift that will not sort itself out. LumenCrate is a pure deduction puzzle. Each board gives you a handful of job tags — one to three slots wide — and a rail of rule cards beside it. Hang every tag so that nothing in a lane overlaps and every card lights up. There is exactly one timetable that works, and it is always reachable by reasoning. No timer. No chance. No guessing. HOW IT PLAYS • Tap a tag on the lower rail to pick it up, then tap a lane to hang it. • Cards light amber the moment the board satisfies them, and turn signal red the moment it contradicts them — so you always know where you stand. • Lift a tag back off the rail whenever you want to rethink. Nothing is ever lost. EIGHT KINDS OF RULE CARD • Hand — names the crew member a job belongs to. • Order — one job must finish before another starts. • Handover — the next job starts the exact slot the last one ends. • Together — two jobs must share at least one slot. • Clash — two jobs may never share a slot. • Clock — pins a job to an exact start time. • Deadline — a job must be off the board by a stated time. • Interval — an exact wait between one job ending and the next starting. SIXTY BOARDS ACROSS FIVE DEPOTS Start in the Lamp Room with three lanes and a short morning. Work through the Graveyard Turn, the Harbour Siding and the Foundry Yard — where slots get closed off entirely — to the Signal Tower, where tags arrive already pinned and seven jobs have to settle around them. WHEN YOU ARE STUCK Reveal snaps one tag to its true slot. Undo takes back your last move. Narrow rules out every slot the lit cards have already eliminated. All three cost tokens, which you earn by settling boards and by collecting the daily crate — and the depot store sells permanent fittings that give you free charges, cheaper assists and better pay. COMPLETELY OFFLINE No account, no sign-up, no ads, no analytics, no network of any kind. LumenCrate works in airplane mode and keeps everything on your device. Play it on a train, on a plane, or anywhere the signal gives out. Built for anyone who likes a quiet puzzle with a single right answer and no clock running.
