Foldlock: Escape Games

Puzzle Box Mystery for Adults

$4.99

Your mother left you seven folding puzzle boxes. Open them in this escape game to find where she went. No ads, no in-app purchases. For iPhone and iPad. 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. For iPhone and iPad with iOS 18 or later. Built for iPhone Duo.
