Here´s a new and very effective version of the old "Spill The Drink Card Marking Scam."
The scam has a player sitting on a blackjack game with the dealer dealing the first card. The player receiving the card in first position sees the card is an Ace and proceeds to spill a drink on the card. The card is quickly changed out by the table games staff and replaced with a new Ace. Little does the staff realize but the cards were in play for almost an entire shift. The player involved in the unknown scam will simply look for the bright white edge of the new Ace when the deck is presented after the new shuffle for the cut. He will cut one card in front of the Ace and have a double digit edge over the house when he receives the Ace.
This scam is very easy to pull off. If you take several decks of used cards and place a new Ace of Diamonds into the mix, the newer white border easily stands out and presents the perfect cut and steer target.
