Riichi Arise

Set up a wind-board table in Minecraft and play a full game of Riichi Mahjong (Japanese Mahjong) with friends or AI. From the dealing animation, calls (chi/pon/kan) to riichi, ura dora, yakuman, and the final scoring announcement, everything is completed within the match.

• Wind-board table: A 2×2 mahjong table block and a compact small wind-board 3×3 single-block version; the two table layouts switch automatically with the blocks.

• AI opponents: Built-in RiichiBot: combines tile efficiency and danger level to make decisions on discards, calls, and riichi.

• Diverse characters: Includes 6 offline built-in characters, each with their own play style and voice, plus about 100 online characters that can be downloaded and cached on demand.

• Paipu (game records): Each match generates a paipu record, which can be saved locally, viewed in a list, and replayed.

• Table snapshots are synchronized filtered by viewer, and you can set whether to display match content.

• Optional LAN access (disabled by default): You can enable an NDJSON over TCP interface on a local port to subscribe to table snapshots, sit down as an external player, and submit actions, making it convenient for scripts or external AI integration and debugging.

Notes

• Online character voices are downloaded on demand from third-party sites on first use and cached locally; only offline characters are distributed with the mod.
• When TLM / Patchouli is not installed, related features are automatically and silently disabled, without affecting normal matches.
