At one of the casinos here in Southern California they play "card craps" this way:

There are two automatic shufflers on either side of the dealer. One shuffler is loaded with six "red cards" and the second shuffler is loaded with six "green cards." Each card is numbered Ace through 6 to simulate the six sides of a die.

The shuffled red cards and shuffled green cards are then placed on the table lay-out in positions numbered 1 through 6. If the 5 card happens to be placed in the 5-spot, it's random chance.

A player at the table is given two dice to roll -- one red and one green. The faces on the two dice choose which of the two cards that the dealer will "flip over."

For example, the dice might show 2 and 2, and when the two 2-spots are turned over, they might show a 3 and 5 for an "8."

At this one casino, I noticed that there are two sets of red cards, and two sets of green cards in each automatic shuffler. While one hand is being played, the shuffler is shuffling the cards for the next hand.

And this got me to wonder if players ever ask to check the cards to make sure the sets never get "mixed up"?

Accidents happen. A couple of years ago I was playing in a poker tournament when two players in the same hand turned over the Ace of Hearts. In this case, a new deck was being used and the dealer failed to notice that an Ace of Hearts was in the place of the Ace of Diamonds.

Can you ask the dealers to check the cards? I think asking after every hand would be a problem. But perhaps once a half hour or once an hour just to keep the game "safe"?
