I was taught the basics of mahjong last year, and I've been trying to use Tenhou to get more of a grip on the rules.There are still a few things I'm confused on.
What is the significance of the dora?
There are times when I can't declare tsumo or ron, even though I have 4 sets (pon/chi/kan) and 1 eye. My 4 sets have all been declared but my eye apparently aren't valid for tsumo/ron (like 2
).
And what happens when you disconnect from Tenhou in the middle of a session? There are times when I've had to leave abruptly.
