I saw on an old Casino Diaries episode that comps are computed by a percentage of your "expected loss," given your average bet, number of hands, and house advantage. Suppose three players walk up to a blackjack table, buy in for $10,000, and play $100 a hand for one hour. One goes broke, one wins $10,000, and one breaks even. Theoretically, all earn the same "comp value." However, in real life, wouldn't the casino give the standard comp to the breakeven player, a larger comp to the player who lost the $10,000, and the biggest comp to the player who won?

I now live in Las Vegas and have updated my address with all the slot clubs. I’ve noticed that I never get advertisements for free rooms or discounted rates anymore. Was I better off leaving my previous address (where I still get mail), so it would look like I was a visitor and not a local?

Which casinos have free pull machines in them? I know Bally's used to have one, but I don't think it is still there.

Do casinos rate all table games (for comps) in the same way?

Which casino had the first slot club?

How do I use my comp dollars? I belong to many slot clubs and have built up comp dollars, but I don't know how to use them toward my hotel room or my meals when I visit Las Vegas.

How much does a person have to bet to be classified as a high roller?

We come to Vegas once a year (five-day stay). I usually run about $500 through on video poker a day. I follow your good-machine advice and play several hours. Is it really worth my while to remember to use a slot club card at all casinos?

I’ve been assigned to a casino host who often calls with comp offers for rooms, show tickets, etc. Is it ever expected that I should tip this host and if so, how much and when? I’m not a huge player, but I did hit some royal flushes at this casino.

I will be arriving in Las Vegas on my birthday this year. Do any of the casinos or restaurants give out good birthday specials?
