101 Tips on How to NOT Lose in Riichi Mahjong

Some friendly advice from a friendly neighbourhood riichi player. Some of these tips on how to not lose in riichi mahjong are all based on mistakes or remarks I’ve done or heard or seen someone else do or thought up of. Of course, I can’t guarantee a win (and I can’t guarantee you won’t lose based on skill).

  1. Don’t deal into yakuman.

    Defence 101 - Yakuman
    Don’t even think about it….
  2. Tenpai doesn’t matter if you deal in.
  3. Be sure you can read all the man/character tiles properly.
  4. Make sure that yakuhai is actually your own/round wind.
  5. Make sure you aren’t in furiten.
  6. If you have a good hand, don’t deal the fourth wind and cause an abortive draw.
  7. Don’t discard a yakuman hand if you don’t need to.
  8. Don’t play with cheaters.
  9. Make sure you go to the washroom/won’t be busy before you play.
  10. Don’t deal the houtei dora unless you know a triple ron will happen (to abort the hand).

  13. Don’t decide to go for nagashi mangan based on your haipai.
  14. Know all your waits when you have a chinitsu.
  15. If you are playing with sticks, know the values of the point sticks.
  16. If you are playing offline, remember to check the ura dora if you win with riichi.
  17. Make sure you have a way of telling if a dora is red if you are colour-blind.
  18. Don’t go tsumogiri just because you’re in tenpai.
  19. Keep your winning tile separate from your hand.
  20. Remember to turn your next discard sideways if your riichi tile was claimed.
  21. When calculating points, make sure you remember the honba.
  22. If you are in last place in oorasu, don’t try to win a hand that would keep you in last.

    East 4 in tonpuusen, stayed last even after winning a hand.
  23. Make sure you have 1000 points before you choose riichi as your yaku (unless your ruleset allows otherwise).
  24. Remember that “menzen tsumo” the yaku is different than “tsumo” the call.
  25. Just because a tile isn’t in your discard pile doesn’t mean you didn’t discard it.
  26. Know how to calculate points so you can calculate how much you need to get into a better placement (whether out of last or into first).
  27. Don’t go for daisuushii if you already have shousuushii and both are worth the same.
  28. Don’t try to go for a standard yakuman if you already have a kazoe yakuman.
  29. Make sure you have the right number of tiles in hand.
  30. Don’t riichi a yakuman hand if it causes an abortive draw.

    Fine, the yakuman riichi was actually the second riichi, but you get the point. (Image courtesy of arcturus.su)
  31. Make sure you remember the order of winds and dragons.
  32. Just because there is an order of winds and dragons doesn’t mean you can chii them.
  33. Don’t go for suukantsu if someone else has already called kan.
  34. Don’t try to use the white dragon as a wild card/joker.
  35. Don’t give up a potential yakuman if renhou is worth nothing.
  36. Make sure you don’t call kyuushuu kyuuhai on a tenhou/chihou kokushi musou.
  37. Make sure you draw from the correct side of the wall.
  38. Even though it may look like a yakuman, it doesn’t mean you aren’t in furiten.

  39. As much as you think it is, the riichi button on Tenhou is not meant to be a tenpai indicator.
