by caxapexac

Riichi Mahjong puts a playable Riichi Mahjong table into Minecraft, for one to four players on Fabric, Forge and NeoForge.

FabricForgeNeoForgeClient and serverMIT LicenseOpen source1.20.1 – 1.21.1

What it does

The table plays a full Riichi Mahjong ruleset, including yaku-specific rules and chankan. Rule presets follow the Mahjong Soul, Tenhou and WRC styles, and empty seats can be filled by bots so a game starts with fewer than four people.

Because the mod runs on client and server, the server and every player need it. The server side handles the shared table state, so players join a multiplayer game from their own installs. Dependencies are listed by the project and must be installed alongside the mod.

Builds cover 1.20.1 – 1.21.1 across Fabric, Forge and NeoForge. The code is open source under the MIT License, and the issue tracker and source code are public.

Key features

  1. Multiplayer tables

    One to four players can sit at the same table, and empty seats are filled by bots.

  2. Rule presets

    Presets modeled on the Mahjong Soul, Tenhou and WRC rulesets set the scoring and play rules.

  3. Yaku generator

    A generator lists the yaku a hand qualifies for, which helps players check their scoring.

  4. Mahjong altar

    An altar block is used to craft items that can be scored and played at the table.

  5. FOV normalizer

    An option holds the field of view steady inside the table area so the tiles stay readable.
