Hi LanaInVegas,
Paul from Angie's List here. We don't have slot machine repair as a category but I can make a few recommendations. We have an "Uncategorized services" category in which some members in other markets have submitted reports on slot machine repair, video game repair, etc. It's possible you can locate a service company that repairs slot machines there. You might also check our "Handymen" category for any highly rated handymen in Las Vegas who work on slot machines. Lastly, you can always call us at 1-888-944-LIST (5478) and ask to speak to one of our neighborhood specialists. We have local area research experts on staff who can help you find a quality company, even if they're not rated on the List.
I hope that helps. Good luck!
Paul from Angie's List
