Morra — Outsmart the AI
Morra — Outsmart the AI. Verified Fair. Morra is the ancient hand game, reimagined for the digital age. Throw a number (0–5), guess the sum, and go head-to-head against an adaptive AI that learns your patterns in real time. But here's the twist: every single AI move is cryptographically committed before you play. Using a SHA-256 commit-reveal protocol, the AI locks in its choice before seeing yours. You can verify every round, every session — right in your browser. No trust required. HOW IT WORKS 1. The AI commits its move (a cryptographic hash is shown to you) 2. You pick your number and guess the total 3. The AI reveals its move + the secret nonce 4. You verify the hash matches — proof the AI didn't cheat ADAPTIVE AI ENGINE The AI uses a 6-model Bayesian ensemble that adapts to your playing style. It starts off easy, but the more you play, the more it learns. Think you've found a pattern? So has it. FEATURES • Real-time gameplay over WebSocket — instant rounds, no waiting • Full cryptographic audit trail for every session • Humanity score — prove you're not a bot • Global and per-player statistics • Session audit viewer — re-verify any past game • Dark, minimal interface designed for focus FAIRNESS YOU CAN PROVE Unlike other AI games, Morra doesn't ask you to trust it. The commit-reveal protocol is the same mechanism used in blockchain systems and cryptographic voting. Every commitment hash, every nonce, every reveal is logged and independently verifiable. THE ANCIENT GAME Morra has been played for thousands of years across the Mediterranean — from Roman soldiers to Italian taverns. It's pure psychology: read your opponent, mask your patterns, and strike. Now your opponent is a machine that never blinks. Play at coldmind.io
