Rinshan, Chankan, Haitei, and Houtei - Riichi Mahjong Guide

- In this episode of Riichi Mahjong Guide, we cover four rare yaku: rinshan kaihou, chankan, haitei, and houtei. These yaku have little to do with the composition of you hand, and instead are dependent on the tile on which you win.
Feel free to leave comments and questions below.
Have you watched Akagi?
I have watched Akagi. That's actually part of what got me into riichi mahjong.
Noice, me too kinda. I started to have interest in it when I read Kaiji part 3 with the minefield mahjong, then I started Akagi and wanted to play it.
@Light Grunty Would it be possible then to discuss Washizu Mahjong by chance?
@@LightGrunty I bet like half the people here are because of Akagi, including me
Awesome videos, they really help with specific situations!
Came across this video trying to figure out if Dora is turned over with rinshan Kaihou and if it depends on if the KAN is open or closed. I saw you turn the dora indicator over before drawing from the dead wall with a closed KAN and thought this answered my question, but then you also turned it over first with an open KAN. This was not what I expected. Do you turn the dora indicator over before discard for all KANs whether closed or open? Sorry to post on an old video, but the answer to this eludes me.
That depends entirely on the rule set. In general, all online rule sets will have the kan dora reveal timing depend on the type of kan, and in-person rule sets will always flip the new dora before drawing the rinshan tile.
Regarding last tile from live wall: if last player draws last tile, then discards tile A, can a player X pung or chi tile A to attain tenpai? But player X must now discard a tile, say tile B. Can another player pung or chi tile B to attain tenpai?
No, players cannot call chii, pon, or kan on the houtei tile (very last discard when only the dead wall remains).
@@LightGrunty Thanks
If you call something that overrides another call (like pon over chi or ron over pon) and it’s not for chankan, do you get the call if you said it after the other person called?
If declared at the same time, pon or kan will take priority over chi, and ron will take priority over any other call. However, if the call that would normally take priority is declared late, then the rule set determines how this is handled.
In most, if not all, competition rule sets, the late call is void. That is because these sorts of calls are expected to take place at the appropriate time. For example, a player is not supposed to wait and see if another player will call chi before they call pon, or worse, maliciously call pon because another played called chi. Even if there were no ill intention and the player simply made their call late, then they should have been paying attention and ready to call at the appropriate time. For clarity, in these competition rule sets, players are expected to call ron, pon, or kan immediately when the tile is discarded, but they should wait a moment before declaring chi to comfirm that no other players call the discarded tile for a ron, pon, or kan. That way, there should be no late calls.
I'm confused about Haitei. I understand that you can win with it, but if the yaku is built around winning with the last draw, and you won with the example hand, is it just about matching everything? Because that hand wasn't otherwise a win. Is it creating a hand with all pairs, sequences, Tris, and quads with no tiles unmatched with the last tile in the live wall?
I'm not really sure what you mean by "matching", but perhaps this explanation will help:
In riichi mahjong, you need two things to be able to win a hand: yaku and tenpai (having a hand that just needs one more tile to win). The shape of a winning hand is usually four sets of three tiles (either sequences, triplets, or quads), and one pair. If your hand is in tenpai, but you don't have any yaku, you would normally be unable to win that hand. However, with the yaku described in this video, like haitei, you could win a hand that would otherwise have no yaku.
I hope that helped. Feel free to ask if you have any more questions.
What I meant by matching was: filling your entire hand with pairs, sequences, tris, or quads. I was confused about haitei because I was wondering how you could win a hand by winning with the last tile drawn if you didn't win, because you had no other yaku. Essentially I don't know why haitei doesn't require other yaku to work. @@LightGrunty
Unless "Winning by the last tile in the live wall" doesn't mean that Haitei requires that you win by the last tile, it means you literally win by the last tile as long as you're in tenpai. @@LightGrunty
Haitei does not require another yaku because it is a yaku by itself. The four yaku shown in this video have little to do with how you build the hand, and are really just little bonuses if you happen to win by these specific methods. However, because they are all yaku on their own, you could win a hand with haitei as your only yaku, for instance.
But if the yaku requires you to win with the last tile then the requirements for it wouldn't be met by claiming a winning hand structure without a yaku. I'm sorry to be so specific xD. Thank you for the replies. Also, I wonder what your opinion would be on the gameplay of this idea I had: If you only have two players each could play two hands , and at the end of the game the score for each of the two seats are tallied and the one with the higher score wins.@@LightGrunty
What about if you get hoitei or the orher one, and you had that north triplet, dont you get yakuhai
If north is your yakuhai, then that would count as a yaku as well. I was mainly using this as an example for when you had no other yaku in these situations, if north were not your yakuhai.
