Foldlock: Puzzle Box Mystery
Your phone is an escape room
$4.99
Six folding boxes and one lighthouse mystery. Close, crack, stand and open your phone to solve them, then come back for a new shuffled box every day.
Your phone is the box.
Foldlock is a hand-made puzzle box mystery. Six folding objects (a jewelry box, a locksmith's ledger, a ship surgeon's case, a child's music box, a folding chessboard and a lighthouse painting) each lock away a letter that was never sent.
On iPhone Duo, the hinge is the lid. Close the phone and the outer screen becomes 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 any other iPhone, a brass lever on the screen does the folding.
• 48 puzzles across six 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
• A story told in six letters: why the Halcyon sank, and where Iris Vane went
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
Pay once. No ads, no in-app purchases, no accounts, no data collected. Progress syncs through iCloud. Headphones recommended.
Built for iPhone Duo. Plays on every iPhone with iOS 26 or later.
