Card counting is not illegal in Nevada casinos. However, using a device to aid in the counting of cards is considered a felony under Nevada laws governing cheating, control board member Randy Sayre said.
Gamblers using the iPhone card-counting program can be detained by casino operators and arrested by state gaming agents.
The program uses four different strategies for card counting. It also operates in the "stealth mode," in which the phone's screen is shut off. The program can be run effortlessly without detection as long as the user knows where the keys are.The Nevada gaming commission was tipped off to the existence of card-counting iPhone applications by the California Bureau of Gambling Control, and although the Nevada board has not received any reports from casinos about players using the applications, they decided to alert the state's casinos in order to raise awareness of the issue.
