Many people remember one-armed bandits standing in passages and small coffee shops, where you could toss a coin and try your luck. Since then, the algorithm of slot machines has changed significantly, which was caused by the transition to new technologies.
Despite the prosperity of land-based casinos, many players have flocked to the online space that offers a variety of slot machines from well-known gaming software developers. In this article, Slotegrator team invites the online casino operators to look into the working principles of online casino slot machines.
How Slot Machines Are Built?
The well-known one-armed bandits were based on electromechanical principle. Once the player pulled the lever, it made the reels spin and then stop on the symbols according to a certain algorithm. The sensors analyzed the combination of symbols and gave out winnings if the characters matched. Later, the electromechanical slots were replaced with electric ones. Their reels were driven by an electric motor; eventually, electronic gaming machines supplanted their predecessors.
Modern slot machines have electronic filling - a processor with a built-in random number generator (RNG). Thus, it becomes clear how a slot machine work — RNG generates random numbers that are impossible to predict.
Can we trust RNG?
The random number generator is encrypted by 128-bit MD5 algorithm. Particularly this algorithm developed by the professor at the Massachusetts Institute of Technology is widely used in electronic security systems.
Although the code was invented a few decades ago, it is still a difficult task to hack it. Besides, the algorithm is being constantly improved: the newest add-ons are used to make it tamper-proof.
Game software developers exclude the possibility of reprogramming the chips at the time of their release. They say that despite the theoretical possibility of hacking, any practical facts have not been registered yet. Thus, thanks to the MD5 algorithm online casino cannot influence the game outcome, providing the randomness of the landing combinations. guarantees the players’ trust to the online gambling resource and protects the casino against unfair players.
Types Of Slot Machines
Modern industry produces a huge quantity of slot machines with different themes and bonus features.
