Hi! I'm a former tenhou 7th dan (highest was about 2400/2800 to 8th dan, but I fell to 6th dan recently), and I'm still trying to figure out both what I know that let me get there, and what I don't know that might be keeping me from going higher. If you want any advice from me, you can just ask and I'll tell you what I can.


I play some other games as well, and I might take long breaks from mahjong occasionally, but I think I'll always enjoy the game.
