Bob Stupak, the former owner and builder of the Stratosphere casino in Las Vegas, gave some notable advice about playing slot machines. He is quoted as saying, “When we put 50 (slot) machines in, I consider them 50 more mousetraps. You have to have a mousetrap to catch a mouse.” That should give you some strong clarification about slot machines, plus some encouragement to learn to play another game when visiting casinos.
