Thank you Oliver for a fun, user-friendly platform for me to play mahjong with friends! We just finished a game. My friend and I were both waiting on a 二萬 to win. She won because she 吃 the tile even though I had two other 二萬 and could have 碰 it. Why did her 吃 take precedence over my 碰?

hi, 赢牌的时候是按照逆时针顺序算得，与是吃是碰无关。

If more than one player could win on a discarded tile, the first one from the discarder counterclock wise wins. It doesnt matter it is a sequence or triplet.
