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…
