av66

av66 is a path-laying logic game set inside a sealed crystal vault. Each chamber asks you to draw a single amber filament across the floor, collect numbered crystals in lock order, and step onto the chest before the move limit runs out.

The av66 unique rule is the combination path: crystals behave like tumbler pins. Take them out of order and that pin never turns, because the filament cannot recross itself. Resin tiles cost extra steps, arrow tiles admit only one direction, and sealed gates stay shut until the current lock sequence is complete.

Ten handcrafted halls sit on four wings, with undo, best leftover-step records, a Burmese vault ledger about Hukawng amber, and a reliquary that stores every opened chest. The whole experience runs as a self-contained vault inside the app, designed for small and large phone screens without cluttered chrome.
