Based on Lucian’s criteria, Russian roullette is the game. Talk about concentrating the senses . . .
If you play a bit, they give you free rooms. For about five years, I would to go to casinos, in NJ and CT, and contribute/drop specific amounts of excess cash. It’s entertainment: like going to a Broadway play.
Only once in that time, did I saw a man who was so excited (I imagine he had lost the rent money) that he was beating the heck out of the men’s room wall.
