Lobbies

Tenhou is split up into lobbies, which are simply waiting rooms for games. Players can only play with other players in the same lobby, and can only watch games from the lobby they were created in. Lobbies are identified by numbers, usually prefixed with an L (i.e. L7447, L8000, etc.).

Tournament Lobbies

Games

There are 6 types of game available to play on Tenhou:

Name	Description
喰断ナシ	Nashi	No open tanyao
喰断アリ	Ari	Open tanyao allowed
喰アリ赤	Ari red	Ari with red fives
喰アリ赤速	Ari red fast	Ari with red fives and half time on turns
三喰アリ赤	3-man Ari red	Ari with red fives and only 3 players
三喰赤速	3-man Ari red fast	3-man Ari with red fives and half time on turns

The two round types (the columns) are tonpuusen (東風戦) -- East only round; and tonnansen (東南戦) -- East and South rounds.

Once upon a time there was also a highlighted mode that would grey out tiles that were immediately discarded after drawing them, in players' ponds. It was removed because people complained about it, though.

Joining games is done by clicking which mode you wish to play in the above table. The pushed down buttons indicate which games you are waiting for, or queued for. Games start when there are three other people (or two, in the case of 3-man) queued. To leave the queue(s), click the ｷｬﾝｾﾙ (cancel) button in the bottom right of the box. The x:y numbers next to each game type show players queued:players in-game.

Lobby Stats

At the top of the lobby window there are three figures. From left to right: total players connected (globally, not just per lobby); total idle/waiting players (per lobby); players in their last round (per lobby).

Game Ranks

You can be selective in who you play, too. On the lobby window there's tabs for three game ranks. Different game ranks require different user ranks to play. Choose by the tabs.

From left to right, the tabs are:
General room (all players of all ranks), Dan room (registered players with dan rank), Upperdan room (registered players with, at least, dan rank of 4 and rate of 1800), Upperdan spectate, Past game spectate, Help.

On the lobby window there's also a menu with assorted things in it. They are listed below.

Minigames

Tenhou also has various minigames that you can play from the minigame droplist:

1. Puzzle 1

   

   This is your classic Mahjong solitaire game. You slide off matching tiles to the left or right until you clear the field. There's up to 5 levels and also a level editor:

   

   It gives you a small text editor to make a field. The syntax is:

   • . for a blank space
   • o for a tile (randomly generated)
   • Maximum of 136 tiles
   • Number of used tiles must be a multiple of four (4)
   • The bottom layer goes first, the next layer after that, and so on
   • Layers are delimited by two new lines
   An error will come up if there is something wrong with what you've made.

2. Puzzle 2

   This game involved matching tiles together that have clear paths between them. Paths can have up to two turns in them.

   

3. Practice Mahjong

   Given a set of tiles, make a hand out of them as fast as possible. This game has a Time Attack mode and a limitless mode, which you select in the menu. You can also pick how many tiles you get at the start.

   

Test Play

You can also play against computers if you want to practise. Although they have no difficulty setting you can pick 3 types of game:

1. Ari Red Fast
2. Ari Red
3. 3-Man
