Nevada Statute
NRS?465.075??Use or possession of device, software or hardware to obtain an advantage at playing a game is prohibited.?It is unlawful for any person to use, possess with the intent to use or assist another person in using or possessing with the intent to use any computerized, electronic, electrical or mechanical device, or any software or hardware, or any combination thereof, which is designed, constructed, altered or programmed to obtain an advantage at playing any game in a licensed gaming establishment or any game that is offered by a licensee or affiliate, including, without limitation, a device that:
1.??Projects the outcome of the game;
2.??Keeps track of cards played or cards prepared for play in the game;
3.??Analyzes the probability of the occurrence of an event relating to the game; or
4.??Analyzes the strategy for playing or betting to be used in the game
Point 4 ("Analyzes the strategy for playing the game") and would make it illegal to use "any type of computerized, electronic, electrical or mechanical device, or any software or hardware, or any combination thereof, which is designed, constructed, altered or programmed to obtain an advantage at playing any game in a licensed gaming establishment "
That being said no one has been able to cite an instance where anyone was arrested or denied payout for doing this with an I-pad-like device or smartphone, etc..
Still I'd hate to have my $25,000 Sequential Royal payout denied because I was using my cell phone that had a picture of a strategy card on it that I looked at while playing. If you use a paper strategy card, that is legal but looking at a picture of the same card on your cell phone or a program indicating optimal strategies while playing in a casino in NV is illegal.
Chances are it will never be enforced using a program or strategy card picture on your cell phone at a video poker machine, but it technically is against the law and could leave you open to be arrested and/or lose a big payout. Again little chance, but ask yourself, is it worth taking the chance before you do it?
