Hi Susan, triple trouble is indeed found on the Bally gamemaker machines, which are getting harder to find as they get older and get replaced with new games. In my travels, I've seen triple trouble mostly in northern Nevada along I-80....check the bars at the locals casinos, that's where most of the gamemakers are. I know the Red Lion in Elko had them last year, with the triple trouble on the menu. The Pioneer and the Golden Nugget in Laughlin may have some, and in Vegas you might want to check to LV Hilton way in the back where the Star trek stuff is, the Imperial Palace upstairs sports bar, the Riviera, Slots a Fun, Circus Circus, and the Tropicana, all still had gamemakers last year. I never saw any in Colorado but I have in New Mexico, if that helps. Good luck.
