This mahjong games list is really great. Maybe I'll play all Mahjong games from the list.

In the movie "Kaiji 2: Jinsei dakkai gêmu" they also play Mahjong. I do not know exactly what minutes, but after about an hour's time. Personally, I find the Mahjong scene very well represented. It was estimated, however, not more than 20 seconds the play Mahjong.
