Woh! I was gonna say Mahjong Time's explanation is confusing and refer to the Green Book (official), but the GB is even worse! • After each hand , the winds rotate, but the players stay at the same place. The East player becomes North, South becomes East, W->S, N->E. (This is like other mahjong rule...

https://www.reddit.com/r/Mahjong/comments/cicql2/automatic_riichi_mahjong_calculator/ The payments for any valid hand are calculated, even if the hand is yaku nashi. This is a "feature" that ended up being a "design choice". How the calculator works is that it first tries to assemble a valid hand. A...

You can find all editions of MCR rules and some translations on my website (as well as EMA Riichi rules and WRC rules): https://ooyamaneko.net/mahjong/ You can find Zung Jung rules on its creator's website: http://www.zj-mahjong.info/#English Edit: It looks like this site have a few broken links. :c...

If by riverbed and seabed tiles you mean winning on the last tile from the wall and on the last discarded tile, then MCR have them.
As well as robbing a kong,

There's a video how-to guide on youtube, even if it might be a bit long:

Of course, I'll also point you to the World Riichi Championship rules:

Almost all mahjong rules have a very similar rulesets, the major difference being the scoring. Some have very distinctive features like dora or jokers; beside that, it's mostly fine-prints. Unfortunately, very few rules have an authoritative rulebook. Others, like Hong Kong, vary from one players' g...

I've updated the style. Spoilers are still KO. @or2az: The links are displayed correctly for me. Have you tried refreshing the page (Ctrl+F5)? What browser are you using ? I'm not sure why the forum doesn't display some images. It finds them when I access directly to the image URL, ... and then it s...

Thanks! The only thing I've noticed which is different is that the Reach Mahjong logo at the top now links back to the site's homepage, rather than the forum's main page. It's intentional, so I don't have to put back the links bar. :P I'll check how embedded images works, it seems a bit weird. I als...

I think it's all good now, or almost. - The spoiler tag doesn't work. :( Super hidden text. - I couldn't find how to change the forums' color on the main page, but it's not much of a problem. - No favicon? I don't remember if there was one. Please report if anything else looks odd or is missing. gre...

Well, it looks like the update fixed the problem!
... If you excuse the style.

I'm currently updating the forum to the last PHPBB version, and for that I need to turn-off extensions, like the recent topics on the main page, and the custom style. I will reinstall extensions later, if they're compatibles. The style don't seem do work on the new version, so I'll remake it, but I'...

That's what I assume.
But it seems the FTP access have changed too

I'll see what I can do tonight.

Some posts are shown blank too (might be related).

Tenpai status could be inferred by other info, like the time to discard, which tiles are draw-discarded, if the discard is dangerous/dora, ...
But on the 5th discard it's very far-fetched, and the winning tiles can be anything.
