I recently visited Las Vegas with a friend from Massachusetts. He doesn't drive but he has a "Liquor ID," issued by the state of MA, which proves (in MA, at least!) that he's over 21. However, this was not accepted by Vegas casinos as proof of age, the stated reason being that this particular form of state-issued ID wasn't in "The Book". So, what is this "Book"? Is there a public listing of which IDs do qualify as proof-of-age in Nevada?

Which casinos still have live keno lounges? They seem to be disappearing...

It was announced that The Cromwell will open on May 21st, so I checked out their website today. I was surprised that their casino floor included a section called 'The Abbey,' which is described as a reserved area with three table games. The room can be curtained-off for privacy – perfect for high-profile guests. In light of a recent incident where the Nevada Gaming Control Board filed a complaint against Aria for blocking two state gaming agents from observing wagering activity in the casino's high-limit area, it appears that such a 'reserved' gaming area with curtains would be a violation of Nevada's law to ensure that the public has access to gaming. Do you expect the GCB would be concerned about gaming occurring behind a curtain? Do other casinos have similar 'private' gaming areas to appeal to their high-profile guests?

I have just spent many frustrating hours trying to co-ordinate my gambling log and the win-loss statements I’ve received from casinos where I played in 2013. I am so confused. None of the numbers on these statements match up with my own very detailed records. What figures should I use on my federal income tax return?

You addressed the Super Bowl and the props leading up to the game. Can you provide a little round-up of how some of the more interesting bets turned out?

Do you know which casinos will be selling the Chinese New Years chips ($8) like last year? I will be in Vegas next week and would very much like to purchase some. Thanks.

In reference to the "Today's News" item from 1/23/14 -- "Props Come Out Tonight" —- is there a website that shows what the prop bets are?

In today’s (1/23/14) QOD you refer to Vegas hyperboles including: "smallest video poker bar." Never heard of it; fill us in.

In researching slot articles, I read that "a new slot machine costs approximately $9,000 to $11,000. In Nevada it normally takes a casino about 100 days of operation to recoup the investment." One hundred days seems very long to recoup the cost of a slot machine. On average how much do Strip and downtown casinos make per day? Also, what slot machine is the most expensive slot machine to have ever been purchased?

A story from Bloomberg says that the LVH Superbook has 14 players holding tickets for Auburn to win the national championship at 1,000-1 odds. Can a player offer to sell the bet back to the casino (before the final game)? Are players allowed to sell bets to other players?
