The NSUD are still up and running at McCarran Airport near Starbucks.
As far as I know it is only available BEFORE you go through security.
On the "other side" is the typical airport rubbish.
Had played 50c NSUD in the past, sometimes winning and sometimes losing
$50-100 here and there before departing flights. Switched to $1
yesterday and got the four deuces (dealt 3) with a "wasted" ace that
would have only mattered in the 96% Deuces Bonus offered on the
adjacent machine. But it's nice to have more than made up for any
airport play in the past.
Besides the NSUD I could not find any other game worth your while.
Attendant hand pay of ticketed $1150 thought I had hit a 25c royal.
