Gaming commissions in Nevada are informing casinos that a new card counting program has made its way to the Apple iPhone, called Hi Lo. This program can be used in the Stealth Mode. When the program is used in the Stealth Mode the screen of the phone will remain shut off, and as long as the user knows where the keys are located the program can be run effortlessly without detection.
Randall Sayre, of the Nevada Gaming Commission says "Use of this type of program or possession of a device with this type of program on it (with the intent to use it), in a licensed gaming establishment, is a violation of NRS 465.075."
