Here in Tahoe this week, Bill's have the only machine. Not sure why I play, but can't resist even though I don't need the strikes. Still have a few red caps , looks like maybe one per tube. Just to show you on averages, won 3 first time thru on $160, later that night won 17 with $80, hit the triple bars with the strike symbol 4 times. Played again tonight, the other machine won 9 strikes (1 red ) with $20, hit the triple bars again twice....Guess so far average in my favor, now if only can find a good crap table.....
