Four Keys Puzzle

Four Keys Puzzle is a logic vault game built around a dual-check cipher: four unique keys must sit in the correct slots and at the correct quarter-turn rotations before the bolt work releases.


Each vault is a self-contained locksmith challenge with limited attempts, clue-driven reasoning, and clear feedback lights that separate wrong identity from wrong torsion. Progression moves across twenty-four casino-floor cages, from training coffers to the Master Locksmith gate, with stars and score rewarding clean clears.


Around the core puzzle, Vault Codex explains lockcraft and key heraldry, achievements track milestone breaches, and locksmith stats keep your floor record. The experience is fully offline, tuned for small and large Android screens, and styled in deep forest green, crimson, and gold.
