📜 How to Play & SubMilli Duel Protocols
Official match rules, InstaBrackets tournament pacing, and zero-trust SHA-256 cryptographic verification.
✂️ 1. Rock Paper Scissors (1v1 Duel)
Classic competitive 1v1: Rock 🪨 crushes Scissors, Scissors ✂️ cuts Paper, and Paper 📄 covers Rock. Identical throws result in a draw and an immediate re-throw.
• Practice solo against BOT SubMilli or click INVITE FRIEND to generate a private SM-XXXXX P2P room link.
• Keyboard hotkeys: 1 Rock, 2 Paper, 3 Scissors.
☝️✌️ 2. Odds or Evens (1-2 Shoot)
Fast binary mind-game: one player is assigned ODDS and the other EVENS. Both players simultaneously throw 1 Finger ☝️ or 2 Fingers ✌️.
• Total = 3 (1 + 2) → ODDS
WINS.
• Total = 2 (1 + 1) or 4 (2 + 2) →
EVENS WINS. Zero draws—every single throw scores a point.
🏆 3. InstaBrackets Party & Jumbotron Tournaments
4 & 8 PLAYER LIVE BRACKETSHost an instant couch, LAN, or stream tournament on a primary PC/TV Jumbotron while players join from their phones (or extra browser tabs) with zero downloads:
Open the InstaBrackets tab on your main screen. Players scan the QR code or open the join URL and enter their tag.
Pick 4 or 8 Players, RPS or Odds/Evens, and First to 3 or 5. Any open seats auto-fill with BOT SubMilli.
Every bracket match starts with a 3-second ready countdown. With the 5 SEC Shot Clock active, failing to throw before the stadium horn BUZZZZZ! forfeits the round.
🔐 4. Anti-Peeking SHA-256 Commit-Reveal Protocol
Every 1v1 P2P throw generates a 128-bit cryptographic nonce
locally in your browser and transmits only SHA256(move + ":" + nonce + ":" + round) over Cloudflare Durable
Object WebSockets until both players lock in—making packet sniffing or mid-round peeking mathematically
impossible.
