I once saw a game played with 3 dice in a cup at Foxwoods. It had a large illuminated table top to lay bets on all the various outcomes that 3 dice could produce. It seemed to be popular among an Oriental crowd and I assumed it was an Asian game. I thought I might see it at Resorts World, but never came upon it while there. I have never seen it anywhere else but Foxwoods. Does it ring a bell to the point you know the name of the game? If you do know the game, do you know if it is anywhere in Vegas?
This sounds like sic bo to us.
According to WizardofOdds.com, sic bo is an ancient Chinese dice game that's very popular in Macau. The game uses three dice and a table, as you saw at Foxwoods, with a variety of betting options based on the various results of rolling the three dice. The WizardOfOdds page goes into minute detail about the different bets and their house edges and the varying rules by jurisdiction, covering Macau, Australia, and Atlantic City. Though the game used to be much more common here, Las Vegas isn't mentioned on the page.
As far as we know, the only casino that offers sic bo in Las Vegas is the Venetian. At least the last time we were there, they had one table. That makes sense, since before the pandemic curbed international travel, the Venetian hosted plenty of Asian players as a result of the cross-marketing with its Macau and Singapore casinos. Whether or not sic bo survives the sale of the property later this year is anyone's guess, but we tend to doubt it.
I don't mean to be stuffy or priggish or put anybody down, but I want to inject the fact that the proper name for game is Sic Bo (i.e., with initial capital letters). Oh, the clear majority of the references you'll see either in print or on the Web will be in all lower-case, but that doesn't mean anything. Especially on the Internet, ignorance and indifference and errors abound, so that fact that something is the majority occurrence means nothing. I saw a Sic Bo game at New York-New York in the early or mid-2000's, and it definitely did not have the label "sic bo"; it was either "Sic Bo" or "SIC BO". But let's get to the game itself. Outside of "even-money" bets ("Big" and "Small"), which have a house edge under 3%, the bets' house edges range from bad to horrendous. With its lights and its interesting and somewhat unusual table layout, the game can really draw you in and tempt you to make the more-intriguing "number" bets, but they're probably only going to clean out your wallet.
