Every time a player moves up in rank, the points in Tenhou default to the value indicated at '''base points''' {{kana|初期pt}} column. If those base points fall below zero, then the player drops a rank. If the player attains enough points to surpass the '''target points''' {{kana|昇段pt}}, then a rank promotion occurs. | Every time a player moves up in rank, the points in Tenhou default to the value indicated at '''base points''' {{kana|初期pt}} column.

At the very beginning, every player begins with a base ELO rank of 1500. That number increases or decreases based on wins or losses, as well as the relative ELO rating of the other players. To access the higher two lobbies, both '''tokujou''' {{kana|特上}} and '''houou''' {{kana|鳳凰 }} also require minimum ELO rankings. For tokujou, a 4-dan {{kana|四段}} may access the lobby with a minimum of 1800. Houou players are required to retain an ELO of 2000 or greater. | |||
The change in rating after each game is applied as follows:<ref>http://arcturus.su/tenhou/ids-ranks.html</ref> | |||
Rating_change = Adjustment*(Base+(Average_table_rate - Own_rate)/40) | |||
Adjustment = 1-(Games_played*0.002); if games played < 400, 0.2 if games played >=400 | |||
