I understand that 打牌 can mean playing mahjong or playing cards but I'm having trouble working out which one it is. I know nothing about cards or mahjong. The sentences related to 打牌 so far is: -洗牌 (shuffle) -Someone inviting another person the play by asking: 不玩两把? -轮到他摸牌的时候 (the words 摸牌 appear a lot) -快速的整理了一下牌，抽了一张扔了出去，出声：“三条。” Can anyone help work out whether they are playing mahjong or cards? And what is the meaning of 玩两把 and 三条 Thank you!
