Each shuffle-Rng starts with a seed: a beginning number produced by a certain procedure. Many online casinos seed their shuffles using the casino servers clock and date / time.
Generally online casinos shuffle cards using a pseudo-random generator. True randomness does not exist with computers – they make their decisions upon triggers or past estimations. So one shuffle made by the computer is likely based on the last pseudo-random shuffle it performed. There are millions of possible seed RNG (random number generator) combinations that the computer can choose – making it hard to predict – but not as hard as you might think.
Each shuffle-Rng starts with a seed: a beginning number produced by a certain procedure. Many online casinos seed their shuffles using the casino server’s clock and date / time. So, if a programmer can decipher the casino server’s main clock timing, he can figure out the shuffle-Rng seed used. And if he can figure out the seed, he can work out in what order the cards will fall… and thus, his software can tell you whether to hit or stick on the cards you have based upon forward evaluation of the card order. This is potentially a HUGE advantage.
The good news is that these types of programs ARE currently available online. Most of them charge money to you to purchase – from $50 to $250 is average. Their performance is unpredictable, and some are better than others. There are also a few charlatans out there. Do your research well. It truly sucks to get tricked by a programmer when you’re attempting to trick the online casinos at blackjack! I suggest only purchasing such systems after you’ve had a free trial of them and are convinced that the full versions will work and make you money in the long term. Happy cheating!
