Foldlock

A puzzle box game made for iPhone Duo.

For iPhone Duo and iPhone 11 or later · US$4.99, one-time purchase

Foldlock on iPhone Duo: the title on the cover screen, and the music box open on the inside screen

Built for iPhone Duo

Your phone is the box.

Every box in Foldlock folds the way iPhone Duo folds. The cover screen is the lid, and the hinge is the hinge. Some clues only show when the box is shut. Some only show through a crack of light.

Folded: the inlaid lid of the jewelry box on the cover screen — **Fold it shut.**The cover screen becomes the lid, with its inlay and its locks.

Open a crack: numbers glow in the dark inside the surgeon's case — **Open it a crack.**In the dark inside, things show that never show in the light.

Lid standing up: lamplight through three bottles throws colored light — **Stand the lid up.**Open it flat, then fold it back like a laptop. Mirrors and lamps start to work.

Open flat: the music box laid out — **Open it flat.**Lay everything out: drawers, dials, wheels and keys.

No iPhone Duo? Foldlock also plays on iPhone 11 and later. An on-screen lever moves the lid between Shut, Peek, Half and Open.

Questions

How do I open the box?

On iPhone Duo, fold the phone shut to see the lid, open it a little to peek inside, and open it flat to lay everything out. On other iPhones, use the lever on screen: Shut, Peek, Half and Open. How to play is also in the pause menu.

The lid won't stand up on my iPhone Duo.

Open the phone all the way first, then fold it back until it stands like an open laptop. If you open it slowly from shut, iPhone Duo keeps using the cover screen until the phone is open quite wide. You can also turn on the On-screen lid lever in Settings.

Why is the ? button dim?

In the later boxes, hints take a while to come. The ring around the button fills up until the next hint is ready. Puzzles you have to hear never make you wait.

I can't hear anything.

Some boxes have to be heard. Check the ring/silent switch and the Sound slider in the game's Settings. Headphones help.

Can I play a box again?

Yes. Choose Boxes on the title screen or in the pause menu. Replaying a box never changes your progress.

Does my progress carry over to my other devices?

Yes, if you are signed in to iCloud. Your progress syncs through your own iCloud account.

Where are the leaderboard and achievements?

Tap Game Center on the title screen. You need to be signed in to Game Center on your iPhone.
