ONLINE RIICHI MAHJONG
Play, improve, and understand every decision
Tenpai.gg brings together riichi mahjong games, an ELO ladder, nanikiru puzzles, a learning path, and AI-assisted game review.
A complete place to improve
Practice hand reading, shanten, ukeire, value, and safety without separating theory from play. Every tool uses the same riichi vocabulary and leads naturally from a first lesson to a detailed game analysis.
Competitive, readable, and fair
The server remains the source of truth for games. The client receives neither the wall nor opponents’ concealed hands. This separation protects table integrity and enables consistent replays.
