The tournament format was designed and developed by a group of professional players who wanted to bring the excitement of poker tournaments to equally enthusiastic blackjack players. Get21 is the first online gaming website to offer state of the art, advanced multiplayer blackjack tournaments application 24 hours a day, 7 days a week. Get21 members can participate in a radically intense blackjack challenge at any time, around-the-clock.
We’ve opened a new door to a true-to-life gaming experience with combined cutting-edge technology and a superb visual graphic interface to deliver an authentic, blackjack table atmosphere.

Online Blackjack Tournaments - Fair Game

We take fair game play in earnest and would like to familiarize you with two critical elements in the development of any virtual card game: the use of unpredictable random numbers and an unpredictable ordering/shuffling of the deck.
Random Numbers

We use an entropy (1) based random number generator (RNG) available from the Linux operating system.

The random number generator gathers noise from the system, device drivers and other sources such as network activity and CPU utilization, into an entropy pool. From this entropy pool random numbers are created. Linux provides the /dev/random device. Reading this device from code provides random numbers.(2)

Our application was developed to take seeds from that entropy pool periodically. These seeds serve as the starting number for an elementary cellular automaton (3). Get21’s cellular automaton is an array of binary values. We use a complex rule (rule 30) for state transitions which creates new random numbers from the seed value. Rule 30 is known to produce randomness. It is of special interest because it is chaotic and is used as the random number generator for large integers in Mathematics. (4)

Once we have that seed, we produce random numbers through the state transitions of the cellular automaton. Our cellular automaton has 256 bits. We take the additional step of randomly selecting one (1) bit from each of the successive 255 rows (states) to produce absolute random numbers, hence a randomly distributed deck of cards.

Our random number generator passed two (2) standard tests: the Diehard(5) and the ENT (6) tests. More importantly, our code has been inspected and certified by an independent testing lab specializing in the analysis, review, and certification of software for gaming and cryptology
Shuffling

How the deck is shuffled is equally important. We have used an algorithm (process) that ensures a true randomized shuffle. The process does not favor any one card or any one position in the deck.

We then assign each card a 256 bit random number. This tremendous number is greater than 1 with 77 zeros after it. With each card given its own huge random number, we then sort the deck by those same random numbers, placing the cards in yet another random sequence. This algorithm reinforces the theoretical possibility that every conceivable card sequence is therefore likely to occur.
A note on Collusion

Collusion is when two or more players attempt to bet in a fashion which allows added gains. Collusion, simply stated, is cheating. The Get21 application was designed to detect collusive behavior. It will immediately detect collusive patterns and will thoroughly begin to monitor the various elements involved in the collusion attempt. The system will generate an incident alert, send the information through the appropriate channels and Get21’s security staff will effectively halt the activity within minutes. Get21’s anti-collusion detection system has proven to be effective against individual cheating. In cases of collusion, the publics' help can assist us in putting a swift end to these incidents. If you believe you have been the victim of collusion, we ask that you notify one of our hosts by email. Please note the ‘hand’ number at the top of the screen. Our security division will be able to correlate the information to the system generated incident alerts.

Collusion affects ALL players. It is unfair to everyone and will not be tolerated. Those members who are caught, will be barred from playing at Get21 forever.
