How to Stay Off Tilt and Climb in the Ranks

How to Stay Off Tilt and Climb in the Ranks

If you’ve played mahjong for long enough, you’ll know that have everyone has their ups and downs. Their flow and no flow. Their Tenhou and their double riichiing of said tenhou. Situations like going into orasu after a hard fought 16 hand+ game, only to fall into 4th to a 3rd turn oya mangan on a sole 8m wait. Stuff like this can leave a particularly bad taste and might be the start of your 5 4ths in a row streak. You could go ahead and just blame this phenomenon all on your “bad luck”, “dumb luck of my opponents”, and of course the ever powerful ‘flow’. Though always be aware that luck flows both ways.

‘Dumb Luck’ is one of the most common causes of going on tilt. When you feel like you’re playing a ‘perfect’ game, only to have it fall to some bullshit tanki wait with a dora ankou or an ipptasu tsumo in orasu… No matter how hard you try this ‘dumb luck’ will not go away, but you can decipher this luck to better understand when and how it can occur and what you can do to respond to it.

Mahjong News 20-01-2016

It’s been a while since the last news post (and post) so let’s jump straight in:

Message from Benjamin Boas
Benjamin wrote the following message to the Osamuko facebook group and asked if we could crosspost:

Recent efforts to spread riichi all over the world have been wonderful to see, particularly Daina Chiba’s book, the first publication for players who have advanced beyond an introductory level.
I’m posting this image to remind people that ever since the early days of international competition, major figures in the Japanese world have been supportive of efforts to spread the good word about riichi. The best example of this is Kyoichiro Noguchi, founder Takeshobo (publisher of Kindai Mahjong), who probably did more than any single person to promote serious competitive Mahjong at an international level. There are many others who donated significant time and resources in the “early” days, including Ichiro Tanioka, Hirokazu Baba, Ryan Morris, and Alban’s Chiyuki Funakoshi.
I encourage leaders of future projects similar to Daina’s to reach out to people like the above, if only to let them know of the community’s progress. They will appreciate the information and if they are in a position to help they probably will.

Daina Chiba’s Riichi Mahjong book

Daina Chiba has wrote an excellent free mahjong strategy book. I highly recommend everyone to read it!

Tournament in Rochester, New York and other American activities

There will be a mahjong tournament in Rochester in March. Deadline for registering is the 28th of February and it’s just $35 to register, which is really cheap for a mahjong tournament! Visit for more information.

PAX East:

The USPML will be running a booth for the 3rd year in a row at PAX east. Badges are sold out but if you already have one, make sure to check it out!


Yenpress had licensed Saki as a digital only release in July 2015. The first volume was released late Decemember. While the translation is shaky regarding mahjong terms, it’s a good idea to support it as this could lead to more mahjong manga being licensed! Volume one can be purchased on the various platforms listed at for $2.99/£2.49

A Step Forward (Mahjong Japan Series)

This month, the Japan Professional Mahjong League debuted a new tournament, the Mahjong Japan Series. This series gathers 12 players who have either won a major title in 2014, voted by the public during a live stream or were recommended by JPML. The 12 players are:

Fujita Susumu (Saikyosen)
Masayoshi Ara (Mahjong Grand Prix MAX)
Naoya Maeda (Hououi)
Hiroshi Yamai (World Riichi Championship)
Hideki Sakurai (10 Dan)
Jun Murakami (Saikoui)
Taro Suzuki (Janou)
Ooi Takaharu (RMU League)
Yuudai Maehara (JPML’s recommended pro)
Masayuki Katayama (JPML’s recommended celebrity)
Naoki Setokuma (1st Fan pick)
Satoshi Fujisaki (2nd Fan pick)

What’s fascinating about this is JPML don’t normally work with other pro leagues (with the only big exceptions being WRC and Saikyousen), and it’s the first time the WRC rules have been used in Japan by a professional league.

If you have niconico premium, you may watch the timeshift here:

Bots on Tenhou? More likely than you think!

Inspired by Shogi’s ‘Denousen’, a niconico sponsored AI vs professional tournament, Tsunoda has posted on Tenhou’s blog a few months ago that he wanted to hold similar tournaments.

While bots were previously banned from Tenhou, with permission from Tsunoda, programmers may now allow their bots to play in joukyuu, and must also wait for Tsunoda’s permission before letting it run loose in tokujou if it reaches that level.

Bots have a special prefix “ⓝ”, which stands for Nonplayer, to distinguish them from players. There’s currently one bot that I know of, ⓝ爆打. It peaked at around 5D R1850~ but has recently fell to 4D R1780~ and Tsunoda is still unsure if he should allow it to enter tokujou. Naoki Mizukami, The author of 爆打, has wrote a few papers (in Japanese) about Mahjong AI, these can be read on his site. All of the bots games can be viewed at
