Mahjong Strategy: This is Tenhou

Mahjong Strategy

This article is a kind of “bad beat” story in Tenhou.

Hi all, thank you for checking this website! Today I was at very dissapointing situation on South 3.

What to discard ? If you see my hand only, there is single choice, 4s. But in Tenhou, you always have to watch the player on tentative 4th position.

This is South 3, so he must have high score hand, at least 8,000 or more. We don’t know if he got Tenpai (1 tile to win) or not. How 4s is dangerous ?


I thought there is large possibility that he is 1 shanten (2 tiles to win) and there is still many dangerous tile, so discarded 4s without such large concern, but the result was …

Disaster… With this choice I slipped to 3rd place and lost 90 points (8dan will get 90 points when 1st place at Tenho).

After I played, I checked this game record. I still think 4s is the best choice, but some Tenhou player may choose other tile like 9p. I am not sure which is better…


In every article, I express 1 circle as 1p, 1 banboo as 1s, and 1character as 1m.
