Basic user guide
Tenhou.net is a Japanese site, with limited English support. There are translation add-ons (for English and French) available for Chrome and Firefox, which translate the interfaces for game play, registration, preferences and statistics.
Game lobby
The game lobby gives players access to game rooms, with number of rulesets to play with. Here, players have access to the different game rooms and player statistics.
Game interface
| Riichi | Chii | Pon | Kan | Ron | Tsumo |
|---|---|---|---|---|---|
| リーチ | チー | ポン | カン | ロン | ツモ |
Most clickable options are near the bottom of the screen. The rest is dedicated to the discard piles, the wall, and other player's hands. In the center, a square display shows the round wind, seat winds, riichi bets/honba, # tiles left, and player names.
Replays
Replays can be accessed via the menu labelled LOG. In the website version, the most recent 30 games are automatically stored within the system, though it is possible to save logs permanently by copying the link and saving it elsewhere (in tenhou.net/3, right click the given log to save the link). In the downloadable client, the settings can be changed so that all replays are saved without limit.
Spectating
Players may use the interface to spectate games, though the games are delayed by 3-5 minutes (to eliminate cheating). Players may spectate Houou lobby games.
Interfaces
Tenhou.net is playable via various interfaces. All of them provide access to the main server, complete with access to the game's player base and statistics.
App
A mobile app is available for Android in Google Play and iOS via the App Store. The app is merely a browser frame that actually uses the /3/ web interface.
Client
The Tenhou client is a downloadable application provided by Tenhou.net. However, it cannot be used without paying a subscription fee. The client application uses the same menus as the browser version, but it also has added features not available on the browser version.
Web (Regular)
An HTML-5 based interface, available at https://tenhou.net/3/. Free for all users and rooms.
Web (4K HD)
A higher quality version of the /3/ interface, available at https://tenhou.net/4/. It provides HD textures, a 3D-like tile display, and official (albeit partial) localization into many languages. Similar to the Windows Client, it can only be used to play in the Ippan 「一般」room, unless one pays the premium subscription fee.
Flash
This interface no longer exists, but was the primary way to access Tenhou for many years before Flash became obsolete.
Game rooms
For Tenhou ranking, the game lobby is divided into four sub-rooms, with specific qualification standards.
- Ippan 「一般」
- General lobby area. Any player ranked below 4-dan and R1800 can play here, including new players and unranked players. The mix creates a somewhat chaotic game environment, where skilled and unskilled players alike play each other.
- Joukyuu 「上級」
- Lower "dan" lobby. Available to players ranked 1-kyuu or higher. Also available to anyone who has paid for a premium subscription.
- Tokujou 「特上」
- Upper "dan" lobby. Available to players ranked above 4-dan and R1800. The lobby consists mostly of 5-dan and 6-dan players all pushing to get into the highest lobby.
- Houou 「鳳凰」
- Reserved for only the highest ranked players in Tenhou.net of rank 7-dan and R2000.
Custom rooms
Tenhou.net offers users the ability to play in custom rooms. Here, players may play unranked casual games, without any worry about their Tenhou.net ranking.
