Hi Pete,

The combination that won me six strikes on one spin at Luxor was on one of the machines with the three bars and doubler symbol.

The top line had:
Triple Bar-Triple Bar-Doubler = 2-strike winner

Center Line:
No winning combination

Bottom Line:
Doubler-Doubler-Triple Bars = 4-strike winner

If I had only played one coin I would have gotten nothing -- wouldn't that have been a real bummer!!
