My boyfriend and I play riichi mahjong via phone app (just called Richii Mahjong on the Play Store on Android) and it’s solid. I know that’s not exactly what you’re looking for, but hope it works in a pinch!
I think there’s “sexy” versions in the same way you can find porn poker or shape matching games, if that makes sense.
I think the joke goes:
Why is camping considered an extreme sport?
Because it’s always in tents!
