You can also play on mahjongo.com It’s free and they have several versions (I play Chinese Mahjong so no passing tiles, no cards, no jokers.
I was playing 2x week at the Y and enjoyed it. We usually had two tables, one that played for points (not money) and for points you need 8 points (they aren’t called that but that’s all I can think of) and one table played to win, sort of like gin rummy with 4 groups of 3of a kind/run of 3 and then a pair to win, no matter how many points the hand totaled. I preferred to play the ‘no points’ table but if they needed someone to play at the other table I could be drafted. There were a few people I didn’t like but I let their comments go. Well, one day I had to play with a person I don’t like. She kept making ‘under her breath’ comments and I was getting sick of it. I got a call from a doctor’s office and I said “I have to take this.” It took 2 minutes. Really 2 minutes. When I looked up they said “it’s your turn” but they’d played a round without me and of course the tile I needed for mahjong had been played. The person I didn’t like said “You missed it, too bad.”
Last straw. I left (and then they didn’t have enough to play so too bad for them) and haven’t been back. I didn’t care about winning, I did care about the rudeness of not waiting for me when I HAD waited for the mean one to take a call just a few minutes earlier.
My daughter is now hooked on it and she’s been teaching her friends and I bet we are all playing wrong but who cares, we all are having fun. Even my non-math daughter liked it.
On Mahjongo.com, I do have to play for points and the computer won’t let you override it, but it is fun and you DO get points for hands I never would have thought of (something called a half flush, special hands with terminals, seated winds, prevailing winds, more points for kongs) but you do play fast so can play a lot. Also, since you are always playing bots, you lose a lot because the bots never play the wrong tiles (I do, by hitting the computer wrong), know which tiles have been played (I don’t), etc. Still fun.
So play to have fun. Play whatever style of Mahjong you like, let your friends take a phone call from their doctor, and DON’T mumble under your breath.
Oh, if you need a 4th (or even a 3rd) Finn the wonder dog is pretty good. He even won a game. His bed time is 8 pm so he can’t play all night.
