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
| Riichi | Chii | Pon | Kan | Ron | Tsumo |
|---|---|---|---|---|---|
| リーチ | チー | ポン | カン | ロン | ツモ |
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.
Individual player statistics
Players with registered IDs have various statistics tracked by Tenhou.net. These numbers can be read on the right side of the lobby window.
Replays
Every replay is accessible via a "replay game link". It is accessible via the drop down menu labled: 「メニュー」 (menu). The first item is labled 「牌譜の管理」. A sub-window, as shown on the right, pops up. The replay links are available here. While they're stored under three tabs, the latter two display the exact game links.
Only a certain number of links are available at the time. Usually, the most recent 30 games played are accessible, as they are stored within a queue. It is possible to save and retain older game links by copy-pasting them elsewhere. This Wiki itself is full of old replay links. Users of the Windows client do not need to worry about losing game links.
Spectating
Players may use the interface to spectate "live games". However, they're not exactly live games, as they are actually delayed by 3-5 minutes. This is to eliminate any sort of cheating via simultaneous replay viewing, while in game.
In the main 0000 lobby, players may spectate games from either the Houou lobby. As such, any player may be able to watch and see the game play of the highest ranked players, currently in-game.
