Basic user's guide
Tenhou.net is a Japanese site. So, anyone, who is not familiar with navigating Japanense sites, may have some difficulty.
Game lobby
Game interface
During the game, most of the clickable options are near the bottom of the screen. The rest is dedicated towards other players' hands (unrevealed of course) and the discard piles in the center. Also in the center, a square display shows players' point standings, names, and rank. In addition, the current wind round is indicated in the center square as well as the number of honba as well as the number of riichi points on the table.
