Many people remember one-armed bandits standing in passages and small cafes, where you could toss a coin and try your luck. The principle of operation of old machines has changed significantly; new technologies have appeared.
Despite the existence of land casinos, players have flocked to the online space where various devices from the well-known game software developers are available. Slotegrator provides an overview of working principles of online slots, which each gamer should be aware of.
How a slot is organized
Well-known one-armed bandits were electromechanical. A player pulled the handle, the reel rotated pausing on certain characters. The reel rotated on a metal rod and was stopped through the brake system with a certain algorithm. Sensors analyzed the combination of symbols and gave out winnings in the case of characters match.
Later, the electromechanical slots were replaced with electric ones, where reels were driven by an electric motor; eventually, electronic gaming machines supplanted them.
Modern emulators, standing in the casino gaming halls, have electronic stuffing - a processor with a random number generator (RNG). The work of slots in the casino is based on this principle. The generator produces random numbers; the combination of symbols on the reels should be different from the previous one.
Can you trust the RNG
The random number generator is cryptographically protected by 128-bit algorithm md5 to be recorded with 32 hexadecimal characters. This algorithm, developed by the professor at the Massachusetts Institute of Technology, is widely used in electronic security systems. In particular, personal computer passwords are protected by md5.
Despite the fact that the algorithm was developed a few decades ago, it is a difficult task to hack it, which occupies a considerable amount of time. The algorithm is constantly being improved; the newest add-ons are used to make it tamper-proof.
Game software developers eliminate the possibility of reprogramming the chips even at the stage of their release. Experts say that despite the theoretical possibility of hacking, any practical facts have not been registered yet.
The gaming machines use algorithm md5, thanks to which a casino is in no way able to influence the outcome of the game, ensuring the randomness of falling combinations.
Variety of slot machines
The modern industry produces a huge number of various gaming machines, which have different thematic design attracting bonuses and special game modes. However, the slot apparatus remains the same.
Manufacturers of gaming software release slot machines with three or five reels. The reels contain 20 to 25 different characters, the appearance of which depends on the slot themes. Depending on the number of reels and symbols, 8 thousand to 9.8 million combinations may fall during a game. By no means all of them are winning.
Many developers have introduced extra characters, enhancing the attractiveness of the machine - wild, scatter, bonus, and joker. These images bring large cash prizes, and provide an access to special bonus levels. Bonus rounds include free spins promising significant winnings.
Lines and payouts
The payout depends on the bet and the combination of symbols. There are machines accepting small bets (sometimes less than $ 1) and providing frequent prizes available to a wide range of gamers; there are also expensive spins starting from $ 5, which are primarily used by high rollers.
Each machine has built-in winning combinations - prize lines. They may have different configurations - horizontal / vertical / diagonal / zigzags match of images. The number of lines for payout varies from five to several dozen. The number of active lines, e.g. those that are involved in spins to form winning chains, can be adjusted starting from one and ending with the maximum number, stipulated in each specific slot.
Successful combinations start from three identical images appearing on the active lines. In some cases, a winning chain may be formed of two identical characters. A winning combination is highlighted, and the account is credited with hall chips or real money.
The game performance or slot payout percentages are important factors for gamblers. The US law requires the payout percentage to be not less than 90%. Manufacturers produce machines with 82 - 98% of pay-off. This means the casino, which has installed a slot on its resource, receive 2-18% commission from gaming machine users. The rest of the funds invested by gamers is used for winnings.
