- 📦Foldlock: Puzzle Box Mystery version 1.2Now in Japanese, Korean and Spanish. The game follows your device language; Settings → Language in the game switches it for Foldlock alone.
Now runs on iOS 18 and later, from iPhone XS and XR.
Easier to read: larger, brighter text for hints, letters and menus.
The jewelry box is clearer: its brass caps light up as they rise, Peek shows the carved code on iPad and on iPhone held sideways, and the lever glows when a lid comes free.
On iPad, and on iPhone held sideways, Shut now looks straight down at the top of every box, so the compass turns in any orientation.
The Ledger: the torn photograph can now be taken after leaving the close-up of the lock, and tapping the lock brings the close-up back.
New haptics on iPhone: the safe dial clicks through each number, drawers rumble out, the seal presses into the wax.
The Daily Box Challenge runs through November: finish the six-box story, then come back every day for a new shuffled box.… more - 🆕Foldlock: Puzzle Box Mystery released on the App Store

About Foldlock: Puzzle Box Mystery
Your mother left you seven folding puzzle boxes, and in each one a letter she never sent.
No ads, no in-app purchases, no accounts. Pay once, play offline.
Foldlock is a hand-made puzzle box mystery. A jewelry box, a locksmith's ledger, a ship surgeon's case, a child's music box, a folding chessboard and a lighthouse painting: six objects that fold, and six letters that tell why the Halcyon sank. The seventh, the writing slope she wrote her Sunday letters on, tells where Iris Vane went.
Close the lid to study the top of the box. Open it a crack and lamplight spills through the gap. Stand it up like a laptop and the lid becomes a mirror, a lantern, a lens. Lay it flat to see everything inside. On iPhone and iPad, a brass lever on the screen opens and closes the lid. On iPhone Duo, the hinge is the lid: close the phone and the outer screen becomes the top of the box.
• 55 puzzles across seven boxes, each built around the way its object folds
• Turn dials, slide tiles, read pinholes against the lamp, listen for the wrong note
• Carry what you find from one box into the next
• Gentle hints that wait a little before they give the answer away
Keep playing:
• Replay any box you have opened, with new answers: codes, orders and places change
• Finish all six for the daily box: everyone gets the same shuffled box each day, with its own Game Center leaderboard
• Six curios hidden in secret compartments, if you look closely
No data collected. Progress syncs through iCloud. Headphones recommended.
