20+ years ago, I went through a stage of playing lots of strip mahjong games on MAME, mostly because there weren't (or I didn't know) other ways to play actual mahjong on PC (native PC games that claimed to be mahjong typically were solitaires).

Many of those strip mahjong games are interesting in terms of aesthetics and could be potentially very fun, but they are very blatantly rigged. They typically let you win the first match by giving you a highly improbably good hand, and then do the opposite in the second or third. This quite detracts from the fun, and I pity the people who put many actual coins in them.

I liked to play the ones that had at least one or two matches that felt more or less fair (typically the second and third, or so). I vaguely remember Mahjong Erotica Golf (yes, a mahjong game that drives a golf game that in turn drives porn) as being one of the best in terms of giving a fair challenge.
