The most popular casino game right now is slots. Since 1899, when Charles Fay built the first slot machine, the game’s basic rules have remained unchanged. A player places a wager and spins a set of symbols-filled reels. Each of these spinning reels comes to a halt in a different location. If the reels stop in such a way that they form a line of the same symbols, the player wins. The larger the size of the prize, the rarer the winning symbols are. The paytable specifies the magnitude of the prize for each winning combination.

How do slot machines work?
Reels are still used in the majority of online slots to show the outcome of each spin. The game arithmetic behind the hood still has 3 to 5 sets of symbols (virtual reels) that stop at random points, despite the fact that the reels are displayed by a computer. Why mess with something that has been working perfectly for years?

Modern online slots have a number of innovative features that mechanical reels couldn’t offer. Expanding wilds, scatter symbols, free spins, bonus rounds, and other features are available.

Generator of Random Numbers (RNG)
All fair slot games have one thing in common: the outcome of each round is solely determined by a random number generated by a Random Number Generator (RNG). The RNG generates a random number that “tells” the reels when to stop spinning and so determines the game’s outcome. That is, a game with the same random number must always provide the same result.

The bigger the stakes, the higher the RTP of your betting system (generally). We presume that the betting system’s other regulations stay unchanged.
In slot machines, how are random numbers generated and used?
RNG is a program that creates a random number.
The mathematics module of the game estimates where the reels should stop based on the random number.
The game calculates the outcome of the spin by stopping the reels at the predetermined positions.
The player who initiated the spin is subsequently shown the outcome of the spin.
Every round’s winner (or loser) is solely chosen by luck. The outcome is unaffected by previous wins/losses, other players’ wins/losses, or anything else predicted. In the RNG, it’s just you and electromagnetic noise – pure gambling.

The outcome of a game is unaffected by previous wins/losses, other players’ wins/losses, or anything else predicted.
This reminds me that I need to explain how random number generators work. RNGs are dedicated hardware devices that produce random numbers from electromagnetic noise and are utilized in online casinos. It looks like a signal-deficient old television with a lot of black and white dots. The value of a black pixel is 0 and a white pixel is 1. Take a picture of a tiny section of a TV screen, convert the pixels to 1s and 0s, and save the image as a text file to get a random number.

Every second, RNG hardware creates thousands of random numbers. On the one hand, pressing the start button one second later will influence the outcome of the next round. On the other hand, you have no way of knowing whether the conclusion will be favorable to you or not. As a result, the fair randomness persists.

There is no need to keep track of the amount of money in a slot machine because modern slot machines are connected to a central server and all wins are paid out by casino workers. This notion is false because random numbers operate quite well.
Different sets of abilities are required to run a casino and create good games. Furthermore, gamers enjoy repeating the same games. Those are most likely the motivations behind the establishment of specialized companies dedicated entirely to the development of casino games. It’s also why the Starburst slot is available at so many casinos. NetEnt (the firm that created Starburst) is a self-contained entity.

This is how it works in a nutshell:

Your gaming session is started by the casino.
Your browser talks with the game provider’s servers, not the casino’s.
An independent company also generates the random number and round outcome (the game provider).
The casino only acknowledges your bets and receives notification of your winnings from the game provider.
One major implication of this is that if you’re losing a lot of money while playing a game from a respectable game provider, you can be confident it’s just bad luck. Even if you play your favorite game at an unknown casino, you will be secure in terms of game fairness (though you may not be safe in terms of receiving your money – utilize our casino reviews to discover a trustworthy casino that pays out even when you win large). In the past, I’ve experienced gaming sessions with an RTP of less than 50%.

Here’s an illustration of how a single spin in a casino game works:

How are slots programmed?
In a browser-based slots game, a player pushes the spin button.
The game sends a “spin” message to the game provider’s server.
The required bet is calculated by the game provider’s server. The game provider’s server requests that the casino deduct the amount of money required for the spin.
The casino’s server confirms.
The game provider’s server asks the RNG for a random number.
RNG responds with a random number that is reasonable.
The game provider’s server spins virtual reels and calculates the game round’s outcome using the random number.
The game provider’s server requests that the casino’s server credit the player’s account with earnings.
The casino’s server confirms the win and adds it to the total.
The round’s result is returned to the game, which is played in the player’s browser.
The round’s outcome is animated and shown to the player.
And it all happens in less than 200 milliseconds on average:).

RTP and volatility/variance of slot machines
The two most essential mathematical properties of a slot game are the return on investment (RTI) and volatility. They essentially determine how much and how frequently you win. It is, however, a little more complicated, so I will attempt to explain it to you.

Back to the Player (RTP)
The long-term statistical rate of total money earned divided by total money risked is known as RTP (Return to Player, also known as payout ratio or payout percentage). Because the term “long-term statistical rate” can be confusing, here’s a more straightforward explanation:

The RTP of online slots is typically about 96 percent. Blood Suckers, for example, has an RTP of up to 98 percent.

“The average return on investment (ROI) for online slots is around 96 percent.”

Because it can be stated as a single number, RTP is a very common feature in online slots. It is simple to compare, because the RTP of each slot game is declared by the majority of famous game suppliers. Then posts like “Top 10 Best Paying Slots” are simple to write.

RTP can be used for a variety of simplified calculations, such as calculating how much you’ll lose from a bonus if you keep rolling it over.

These simple calculations will wow your pals while you’re drinking beer. However, you’ll need to account for volatility in more serious calculations (like the ones we made in our bonus hunting post).

Because slot volatility is a hard concept, I’ll start with an explanation of roulette volatility:

When betting on color, you have a chance to win twice as much as you bet, and you win pretty frequently (18 of 37 rounds).
When betting on numbers, you have a 36 percent chance of winning, but you only win 1 out of every 37 rounds.
Depending on the type of bet you make, the volatility of roulette can be readily stated in figures ranging from 2 to 36. Individual victories will be higher if the volatility is larger. You will, however, win less frequently and are more likely to lose your entire money more quickly.

Slots’ volatility
The volatility of a slot game can’t be stated in a single number because the numerous distinct winning combinations can result in thousands of different win values. I’ve discovered that a chart like this is the most accurate method to convey slot volatility:

Volatility of Slot Machines
Volatility of a particular slot machine
The percentage of total wins paid out as various multiples of the bet is shown in this graph. According to the figure above, 15% of total wins are paid out as individual wins with sizes ranging from 2x to 5x the wager, while 10% of total wins are paid out as greater individual wins with sizes ranging from 200x to 500x the bet.

What is the formula for calculating volatility?
Because volatility cannot be stated in a single figure, game providers normally simply categorize slots as “low,” “medium,” or “high.” These categories can’t be efficiently compared or used in computations, but they can give you a general impression of how volatile the game you’re about to play is.

Finding the true slot volatility (as depicted in the figure above) is a tricky undertaking. In essence, you must reverse-engineer a game’s reel set and accurately predict the possibilities of other special game elements. Even for me, this would take a day or more (depending on the complexity of the slot).

The paytable and reel configuration can be used to estimate slot volatility. Look for the winning combination with the most points. What are your chances of succeeding? How much will you be able to win?

I prefer high volatility games since you may win larger sums and enjoy the same excitement with lower stakes. And, because the stakes are lower, you’ll lose less money statistically. This effect is powerful enough to make up for a decreased RTP.

Slots are the most unpredictable sort of game you can play at a casino, with the exception of the lottery. The advantage of high volatility can outperform games with high RTP, such as Blackjack or Roulette. Read this article to discover more about volatility and RTP and how they affect your odds of winning.

How do you make a slot machine more volatile?
If you want to improve slot volatility, try the following strategies:

Use the black/red double-up button. The RTP remains constant, and you may easily raise the game’s volatility to desired levels by gambling until you win a large enough sum.
Increase the stake per line and reduce the number of paylines to one. There are less odds of hitting a win in that line, but you may expect more wins.
