Today is 7-11-13 and there are some betting numbers for you.
7 and 11 are the "naturals" at craps -- the winning numbers on the pass line for come out rolls (the first roll of each game) and the winning numbers for come bets. The 11 or YO is a winning field and horn bet.
You double down on 11s in blackjack. 7 is a winning image on many slot machine games.
13 is an interesting number because in some cultures it's lucky... and according to some superstitions it's not.
So... how do you feel about making a trip to a casino on 7-11-13 ??
