That makes sense.
Offhand, I really don't know where exactly you would even find that game in Vegas today. Aria, Cosmo, and possibly Caesars. Those old style cabinets are not even found in a lot of places anymore. I would start by taking a look in Aria to see if they have it. Definitely not the M or South Point, or Silverton. Which are the 3 places he mentioned that he was staying.
