With my expected up and coming 4th visit to Vegas looming closer I have been practising my VP on a number of trainer apps. Getting better I have one on my iphone that has a "hand checker" where you can tap in which cards you have been dealt and it advises you which cards to hold and discard should you not be absolutely sure. Job only. What are the casinos policies on these devices? It's not a cheat it's just a percentage checker but don't want some "security dude" looking over my shoulder saying "you cant use that in here matey" One other thing, I have seen references to % 99.74 etc. and 9/6 on various threads. How do I work out what the machine is set at? does it display it on the machine, are there set rates for a particular game i.e. Job Db etc. is it a question of a quick math problem to calculate it myself? I have taken it that the 9/6 refers to the pay rate of 3 of a kind to 2 pair. Is this correct? never really gone this deep into playing the game, usually just for fun but if I can increase my %tage play by doing it the right way maybe my fun will increase because I might win or should I say lose at a more palatable rate.
