Crypto Mahjong

CryptoMahjong offers standard mahjong gameplay, supporting 4-player battles, room creation, friend invitations, and ranked matches. The game preserves traditional winning rules and fan calculations while combining online competition with on-chain asset systems, suitable for both casual and competitive players.

1. Basic Rules​

  • Tiles and Players: Standard 4-player gameplay using 136 tiles (including Characters, Bamboos, Dots, Winds, and Dragons).
  • Game Flow: Drawing tiles, discarding tiles, claiming tiles (Chow, Pung, Kong), winning or draw.
  • Winning Conditions: Supports common winning methods like self-drawn win, winning by discard, and robbing a Kong according to room rules.

2. Fan Types and Scoring​

  • Fan Types: Supports common fan types (Basic Win, All Pungs, Seven Pairs, Pure Suit, Mixed Suit, etc.). Rooms can customize fan tables and limits.
  • Scoring Mechanism: When winning, first calculate the fan count, then calculate the score difference based on the base score and fan count. Supports penalty payment, consecutive dealer wins, and wind round bonus rules.

3. Rooms and Tournaments​

  • Quick Match / Custom Room: Quick matching or creating custom rooms (can set fan limits, payment methods, base scores, and detailed rules).
  • Ranked Match / League: Records player ranks using Elo/MMR, with token or item rewards distributed at season end.
  • Tournament: Supports entry-based tournaments using on-chain tickets or tokens for registration, with prize pools distributed by ranking.

4. On-Chain Elements​

  • Entry and Settlement: Paid rooms and tournaments can use on-chain assets (tokens or tickets) as entry fees. Settlement is executed through smart contracts or escrow relays and recorded on-chain for audit purposes.
  • Souvenirs and NFTs: Special event souvenirs, champion avatar frames, or replay rights can be minted as NFTs, which holders can trade or display.

5. Spectating and Replay​

  • Live Spectating: Supports spectator rooms and bullet comments, with key game states recorded on-chain for important tournaments to increase transparency.

6. Anti-Cheating and Fairness​

  • Cheat Detection: Combines client and server detection of abnormal behaviors (e.g., abnormal playing speed from cheats, same IP anomalies) and provides reporting and arbitration processes.
  • Game Verification: Maintains complete game records (action sequences, seeds, timestamps) for important matches for review purposes.

7. Frequently Asked Questions (FAQ)​

  • What if rules differ? Room creators must specify rules in room configuration, and the system displays a rule summary before starting.
  • How to participate in ranked matches? Select ranked mode in-game, and the system automatically matches opponents and records wins/losses and rank changes.

Beginner's Playing Strategy (Beginner's Guide)​

The following are practical playing strategies suitable for beginners, helping you progress from basic operations to game judgment and defensive awareness:

  • Priority Goal: Ready Hand First, High Score Second

    • Beginners should prioritize achieving a ready hand (entering "tenpai" state quickly) rather than blindly pursuing high-scoring complex patterns. Quick readiness reduces the risk of dealing into opponents' wins or timeouts.

  • Playing Safe Tiles Beats Risky Discards

    • Observe opponents' claiming behaviors and discard tendencies. When uncertain about safety, prioritize playing tiles that have already been discarded by multiple players (safe tiles) to reduce the probability of dealing into opponents' wins.

  • Judgment for Chow/Pung/Kong

    • Chow: Consider when it significantly accelerates your winning progress without exposing too much information. For beginners, excessive chowing may lead to unstable hand patterns.
    • Pung: Punging can quickly form sets but exposes hand information. Pung if you can still achieve a ready hand smoothly afterward, otherwise use cautiously.
    • Open Kong/Concealed Kong: Kongs increase scores and provide drawing opportunities but also give opponents more information. Use cautiously in tournaments/ranked matches based on the situation.

  • Discard Order and Tile Retention Strategy

    • Prioritize discarding isolated tiles (unconnected with other tiles, unable to quickly form pairs or sequences), keeping tiles that can form sequences or pairs.
    • Choose tiles based on "versatility": middle tiles (5, 6, 7) are generally easier to combine with other tiles and have higher value.

  • Tile Reading and Probability Awareness

    • Estimate remaining tiles from discarded tiles (e.g., if opponents frequently discard a suit, the safety of that suit increases).
    • When approaching a draw or opponents are about to win, switch to defensive mode, prioritizing safe tiles.

  • Game Pace and Position Awareness

    • When you're the dealer or sitting at the lower seat, you have more initiative and can moderately pursue offensive opportunities; if at upper or opposite seat, focus more on defense and avoiding dealing into wins.

  • Avoid Early Exposure of Ready Hand

    • If ready but the situation is unstable, avoid exposing to opponents through obvious discards or unreasonable passes; when necessary, choose more conservative plays for safety.

  • Proper Use of Auto-Play

    • For beginners, auto-play is suitable for brief interruptions, but long-term reliance hinders learning judgment; recommend using auto-play in training or teaching rooms.

Practice suggestions: Play more in practice rooms and watch replays, focusing on situations where you dealt into wins and made wrong decisions; as experience grows, gradually try more complex patterns and offensive strategies.
