Also, Mahjong Soul's ruling for tenhou is that if you get kokushi, suuanko, and chuuren, they automatically upgrade to the double yakuman version, because for dealer, we cannot distinguish which tile is the "drawn tile". (even though internally mahjong soul does seem to distinguish it).
This applies to Mahjong Soul but not Tenhou.
