333OK

333OK is a sealed-chamber puzzle built around one uncommon rule: artifacts only leave a room when three of the same kind rest in a single well. Each chamber is a cabinet of columns. You take the nearest relic, park it in one of three gold wells or a single side niche, and wait for a trio to lock. A completed trio becomes a seal, frees the cell, and lets the next shelf drop forward. Six rooms wait behind chained columns. Early chambers teach two relics. Later halls add peacock eyes, tiger claws, conch tones, and moon shards. Pressure rises if wells fill without a trio. A lamp can restack a room once. Echo seals of the same relic in a row ease the pressure and mark the keep. A hanging gem collar moves you through Gate, Play, Rooms, Codex, Chronicle, and Rules. The Codex keeps the six relics and their river-port stories. Chronicle explains why keepers refuse pairs. Progress stays on the device. The game is the center of the app; everything else exists to send you back into the next vault.
