But what makes it possible to play online? The merit of the existence of this new pastime virtual, everything is to be given to software programs designed to reproduce perfectly the various games, and especially re-create the conditions for the performance of each hand are assigned to the case just like in the real casino.

To achieve this goal, namely a complete unpredictability of dealing cards, or for example the speed of the roulette wheel, the software is provided with a program for generating random numbers, called the RNG, which stands for Random Number Generator, this program takes different numbers all the time, and each is completely independent of each other, each number is then associated with a particular result, which is then shown to a player from computer graphics.
