AD 3 and How to Use Tenhou

Another Dream Issue 3 has been released! Please check it out in Gensokyo.org’s gallery!

Yes, I do have a page in the issue as a guest art request from Wong. It could have been better even after 3 years of inactivity, but that just means I need to do better next time, right?. Well, here’s the uncleaned version for curiosity’s sake:

Depending on whether or not the script works out will determine if I try to make an entry for AD 4 which is slated for an August release. Maybe in time for C74!

I don’t know if there’s a tutorial anywhere that says how to use Tenhou, but you can click the link below to read how that’s done.

First thing’s first, Tenhou is an online mahjong program that uses Japanese style rules. If you’ve seen/read Akagi, this is one place you can try those rules out. Let’s walk through how you can get started then.

Site Link: http://tenhou.net/

Once you get to the site, scroll down until you see two buttons, one with kanji in it and the other with the word “Play” as shown below and click “Play”:

A new window will pop up and start loading the game. Once it’s done loading, click the link below, and it’ll take you to another screen:

What we have here next is the log-in screen. You must enter something in the name field to continue to the lobby where the rooms are. If you want to so that you can keep track of your performance in the main lobby, you can register your name. Make sure to save the ID that they give you because they will not give it to you again, and failing to remember your registered ID causes the name that was registered to be permanently unusable without the ID.

Here, we have the main lobby which is divided into 5 tabs. The first 3 tabs are where you can play games, but the 2nd and 3rd tab are only available to players of a certain rank. The 4th tab allows you to spectate other games. Keep in mind games are delayed by at least 1 round in the spectator room.

As you can see from the image below, you can play half games (4 rounds) or full games (8 rounds). To enter any room, just click on the button of the room you want to play in and wait until there are enough people to make a game. You’ll see numbers to the side of the button such as 3:52 or 3:8 which follows the pattern players_waiting:players_in_a_game.

Basically there are 5 types of games that you can play with slightly different rules in each. The top three rooms are the 4-player games and the bottom two are the 3-player games. Game room #3 and #5 replace one five-tile with a red tile which acts like an extra dora.

Unlike games in a live setting, there’s a time limit to each round. Normally, each player is allowed 5 seconds + 10 bonus seconds for each turn. The 10 bonus seconds are per round. What this means is that if a player uses up those 10 seconds for the round, that player only has 5 seconds per turn to make a decision. Just to give you an idea of how long games can take, it’s roughly 60-min per han chan.

The nice thing about Tenhou is that it tells you when you can chi, pon, kan, declare a riichi, and even call ron/tsumo. Of course, you can pass if you don’t feel like calling tiles. The one thing that may hamper learning the game properly is that Tenhou doesn’t allow you to call a win during furiten (which will be shown as フリテン at the bottom of your hand) thus preventing a player to ever commit chombo.

Tenhou is not limited to only main lobby games. If you have some friends that you want to play privately with, you can enter the following format in your browser to set up a private lobby: http://tenhou.net/0/?xxxx where “xxxx” is any 4-digit number such as 4567 or 7664. When you enter the url, you should see something like the image below. Just click the first main link to open the pop up:

And that’s it! For more mahjong help, I suggest these two links:

    I like tenhou but there are some rules which might upset some people like myself. For example the tanyao hand cannot be an open hand.

    I believe that open tanyao is possible in some kind of games in tenhou. What I’m sad about is that I can’t do open riichi ;

    The only problem with tenhou is that there is a handicap for players who leave games before finishing or are not from a japanese ip. gather some statistics and you will see the difference.
