Since the existence of the slot machines in 1891, they have remained the first choice of the players in a casino. Today, these games haven’t stopped to improve with more options and various themes to choose from. Moreover, with the development of the internet, slots are also available to anyone who has internet access. The main reason for their success is that they are easy to play as you just spin the reels in hope to hit randomly a series of items on the pay-line. Sometimes, many believe that there are secrets to increase the players’ chance of winning. To answer these questions, understand how slot machines whether physical or on a video screen programmed?

What is the Random Number Generator?

Random Number Generator or RNG is the brain of the slot machine which is a mathematical algorithm that determines the scores of the slot machine. The player’s chance to win even in online slots is, hence, decided by this mathematical algorithm. In fact, when you spin the reel, the RNG generates several thousand random numbers each second. So, be sure that the result of every spin that you make doesn’t depend on the previous outcomes meaning that the machines are fair.

The technical process of the slot machine

Slot machines are typically programmed whether they are virtual or state-owned casinos. It is also the case of the theoretical payout percentage or RTP (Return to Player) to pay out as gains between 82 to 98 percent. Therefore, the players are able to play slots on since most of their games come with high RTP. To make you understand how the operators programmed their slots, here are the technical processes of some types of these games.

3-reels slots

As stated above, the slot machine is programmed to produce a percentage of the money it takes in randomly. Since there are different types of slots, we are going to explain the most played in the casino. The first one is 3-reels slot that is considered to be the classic version as it has the same layout to the original. If this game has 3 symbols, 27 states are possible because of a total of 3x3x3=27. Thus, the statistical probability to hit the winning combination is 1 to 27 meaning that the winning combination will trigger on every 27 spins. The profit paid out to the gamblers in this winning combination must be less than £ 27 (the 27x bet) if the operators want to get the benefit.

The slot machine is programmed each time a player pushes the button “start”. The last three numbers are taken from the number generator. So, this means one number per reel randomly. For example, the operators have to divide the numbers by 3 because their random numbers are very long but the reels only have 3 items each. As for the rest, it can only be between 0 and 2.

8375823985: 3 = 2791941328 remainder 1

3849348303: 3 = 1283116101 remainder 0

6839028421: 3 = 2279676140 remainder 1

As a result, the reels would stop on Shamrock, X, Shamrock appears on the pay-line meaning a losing round in this spin.

Slot machine with extra reels

One of the operator’s tactics to have benefits is to reduce the payout ratio and the probability of winning. There are two options to reach these strategies. The first one is to reduce the profit that the gamblers get in the winning combination. And the second way is to extend the rolls by a loss icon. So, when they add an “X-item” to each reel, the game would have 4 x 4 x 4 = 64 states. Thus, instead of 1 to 27, the probability that the winning combination will appear would be 1 to 64. So, the player has to bet around £64 in the goal to gain £26. This means that the payout ratio has fallen from 96.3% to 40.6%.
