Support

A cabinet of one hundred puzzle boxes. Open a drawer, and the box inside is yours to work out.

How to play

• Travel the cabinet by dragging up and down. Each drawer is one box.
• Tap a drawer to pull it out and open the box inside.
• Drag on the box to turn it over — most catches are not on the face you start with.
• Tap a part to work it: dials turn, pins press, collars lift, drawers slide.
• A box may hold several mechanisms in sequence. Solve one and the next wakes up.

Hints

Every box gives you one hint free. Beyond that a hint costs one credit. Tap the brass token at the top right of the cabinet to see your balance or buy more. Hints describe what a mechanism wants — they never solve it for you.

If you get stuck

• Nothing responds to a tap. Only the live mechanism accepts input. If an earlier part has already been solved, look elsewhere on the box.
• You cannot find the mechanism. Turn the box fully over, including the underside. Some catches are only reachable from behind.
• You want out of a box. Tap Cabinet at the top left. If you have already opened something, it will ask first — leaving discards that box's progress, though the box itself stays open to replay.

Purchases

• One key opens every drawer — a single payment, not a subscription. No ads, ever.
• Restore a purchase on a new device: open the paywall from any sealed drawer and tap Restore purchase. Your unlock is tied to your Apple ID, not to this device.
• Manage or request a refund through Apple: support.apple.com/billing.

Progress and backups

Progress is stored on your device and included in your iPhone backup. There is no account, so it does not sync between devices — but your purchase does, through your Apple ID.
