LAS VEGAS - Nevada gambling regulators have warned casinos in the state about a card-counting program that works on Apple Inc.'s iPhone and iPod Touch that illegally helps players beat the house in blackjack.
Card counting itself is not illegal under Nevada gambling laws, but it is considered a felony to use devices to help count cards.
The Nevada Gaming Control Board sent a memo to casinos last week warning them of the program.
In blackjack, certain card counting techniques help players determine when they are likely to win a hand and adjust their bets accordingly.
Nevada learned of the program from gambling regulators in California, where officials at an Indian casino found customers using it and tipped state authorities.
