And this thread shows the contrast about a good calculator and a bad (or unfinished) one. BTW, that other calculator, the good one, can it show yaku names in Japanese? (roumaji ok).

This hand is the closest I have been yet so far. 1-dot 1-dot 2-dot 3-dot 4-dot 5-dot 5-dot 6-dot 8-dot 9-dot 9-dot 9-dot :back With a copy of both terminals having discarded by the third go-around, I managed to draw the case 9 a few turns later. Late in the hand, the second ippin was thrown away and...

Are you playing Japanese Mahjong? Only the winner gets points, which come from other players points. (This is pretty standard, but some versions, like Traditional Chinese) do calculate for all players.

Clockwise.

This is like the fusion of Miyanaga Saki and Ikeda Kana.

Tora with Dora. Cute.

This has been almost 1.5 years silent... It's one of the easy three, but oh well, why not?

This has pretty much the Tenhou look, down to the gleaming dora... Main difference is the wall is not visible...

Maybe I should look into this game.

Shirluban gave you the reason why. Here the problem is the 1-2-3 meld, that stops the hand from being all-singles (Assuming this particular game allows open-hand all singles, which is quite common). Also the ones in your hand, but at least these could still be changed to something else, but the one ...

Manzu chinitsu, dora 13. Kazoe yakuman. No? Well, it was worth a try...

Hindsight is 20/20, and sometimes, the tiles play trickster, and you got a second ryanwan (2c) right away. That being said, I'm no expert by any stretch of imagination, so take my advice with as many salt as you need, but I think in that situation I would have gone with the honitsu, if only because ...

Any one have some info on the steam game called "Mahjong Riichi Multiplayer"? It's for 9.99, so I only have seen the screenshots. One thing I didn't like it's in the screenshot where you can see a partial list, you see they've gotten for the "Closed +1" route, which we know it's not really how thing...

Yeah, the penalty is big, but it's there to discourage intentional false riichi. Of course, I understand the situation with your fellow player was not an intentional false riichi, but an inadvertant one. In this case, as shirluban said, you took the best option. If this is a very friendly play group...

At this point I would discard and the other one next round, and hope for a last tile win. Unlikely, but I am still positive points in a draw.

You have no yaku. That is the risk of opening your hand.
