From an email I received today: In regards to room comps, we typically look for an average bet of at least $400 per hand with approximately 4-6 hours of play a day on craps and/or baccarat. Because the odds are high on both of those games, they give you a low rating. That’s not just here at Hard Rock, that’s at every casino. Roulette actually gives you the best ratings in tables, and of course, the reel slots do as well. I hope this answers your question. Please feel free to reach out to me with anything you may need. I would be happy to help.
