Today’s real-money and skill-based game ecosystems, from OKRummy and classic Rummy 91 gaming tables to high-tempo Aviator sessions, still rely on opaque fairness, uneven matchmaking, and reactive integrity checks. The demonstrable advance described here is a cross-title, drop-in layer that makes these games provably fair, skill-balanced, and safer by design—while remaining fast enough for live play. It binds transparent randomness, explainable seating, and real-time integrity signals into a single, verifiable standard that players, operators, and regulators can independently check.

The system has three pillars: a provably fair engine for shuffles and crash curves, a Bayesian skill and seating service optimized for rummy variants, and a responsible-play console with cross-game controls. Each pillar exposes open artifacts—cryptographic proofs, auditable seating rationales, and machine-readable session logs—so claims are not just asserted but reproducible.

Provably fair, without compromises: For Rummy and OKRummy, every deck shuffle is produced from a public, pre-committed server seed combined with a client nonce. Before play begins, the server publishes a hash of its seed
