Randomness Control guarantees that the online slot machine games at online casinos are not cheating. What it does is create a sequence of RNG numbers before you start playing the slot game which you can then check at the end of play to make sure the spins weren’t manipulated in any way to make you lose during play. A Random Number Generator (RNG) is a device that creates random numbers designating where the reels will stop on an online slot machine game. Few online casinos offer this randomness control. If you find one that does you can be assured that they are not cheating you. This does not mean that if they do not offer this they are cheating. And if they do offer randomness control it does not mean that they will pay you your winnings promptly. There are many aspects of finding a good casino. One should always start with a new casino slowly. First make a small deposit and test out their system. Withdraw a few times to see how fast they pay. Then you can deposit more play money once they have been tested out.

Randomness control is accomplished by creating a Hash Function. A hash function is a way to confirm that two parties both know the same thing without sharing what that thing actually is. This kind of control allows players to confirm the randomness of the spins in online slot machines. When playing slots, the player can check the randomness of where the reels stop.

The technique makes use of the SHA-256 algorithm (Secure Hash Algorithm family). The basis of the method is that the online casino player receives a “checksum” of the sequence that he is going to play before he begins the play. The checksum is computed with the help of the SHA-256 algorithm that consists of 64 symbol codes (256 Bits), for example:

SJ4NA7DM49C7SKJ34MNBB3233NHT4KA6H4NSH3K83665DF362HNDT39JSBE62NH3

The checksum for each sequence is absolutely different. There are no 2 sequences with identical checksums. The SHA-256 algorithm is applied for the confirmation of information and for forming digital signatures.

As soon as the game is finished, the player will have access to all the elements of the earlier formed sequence. First of all, he can check whether the game was held according to the plan indicated in the sequence. Next, he computes the total sum of sequence on the basis of the SHA-256. If this sum is identical to the one received before he began play, he can confirm that the elements’ sequence which had been formed prior to the beginning of the game was in fact the one used in the game.

A simpler explanation is as follows: before the reels spin and before you place your bets on the betlines a code (hash function) is created from the numbers of the RNG (Random Number Generator) and sent to you. After the spins are over you can open the code and place it in a decoder for the hash function to get the sequence of spins that were designated before the play. This does not guarantee that the random number generator is producing an acceptable payout of say 96%, but it does mean that the casino is not changing reel stops after you place your bets.
