Help me understand Fuuriten
I've started playing a while ago and before I start playing with other people I wanted to grasp a little bit more of the concepts of the game so I play a lot with bots. But this is an issue that keeps happening and I need some professional help to get better.
Help me understand why I was fuuriten here? I declared riichi in my 2 or 3 hand. Waiting for the 2-Man or the East tile . Then the player o the W seat discarded the East tile and I couldn't Ron? Then after this I my hand became furiten. I didnt skip his discard or anything that could justify my hand becoming temporary furiten (permanent since I declared riichi).
This has been happening for a few games and I always get frustrated because I tried my best to avoid getting furiten (not discarding a tile I needed or skipping a tile during riichi) but still keep getting this furiten for some reason and always end up drawing the game.
Please help this foolish beginner understand what he is doing wrong.
