The Technology Behind Online Slot Games

Online slots are one of the most entertaining and easiest games to play in online casinos. All you have to do is wager an amount of money and spin the reels to potentially land a combination of matching symbols that will reward you with massive prizes. As the number of slot players increases, so does the number of slots available online. Go behind the scenes as to how online slots work:

Random Number Generator (RNG)

RNG stands for Random Number Generator, and it is the software that generates random combinations of symbols in a slot game. The RNG ensures that the probability of any symbols turning up is random, keeping the gameplay fair and giving all players a chance to win prizes. This software continues to generate random numbers even if the slot is not in use.


Providers use a series of coding protocols to develop their games. Some of the most common programs used to develop slot games are C, C++, JavaScript, and Python.

RTP, Hit Frequency, And Volatility

RTP means Return to Player, and this is the percentage of the player’s wagered money that the game will return over time. in a game. Most online slots you can find offer an RTP above 90%. Keep in mind that RTP is not an indication of how often a player can win.

Instead, it’s the Hit Frequency that determines how often the game can land a winning combination. In other words, if the game’s hit frequency is 10%, then the slot can generate winning combinations 10% of the time.

The Volatility pertains to the frequency of wins and the number of payouts you can receive in a game. If a game has low volatility, it will frequently give out small payouts. Medium volatility has a moderate amount of wins and payouts. Meanwhile, with high volatility, players can expect large payouts. However, winning isn’t as frequent unlike with low and medium volatility slots.

Graphics And Illustrations

Most slots that you’ll find today contain impressive illustrations of its characters and background using modern graphics, unlike older slots that only have hand-drawn designs. Slot game providers these days use 3D modeling to create realistic characters and settings.

With themes and narratives included in the gameplay, slot games offer a more immersive gaming experience for players and an entertainment value that goes beyond just spinning the reels and winning.

The layout for the animations and illustrations of slot games are conceptualized and developed by each providers’ team of animators and programmers who work together to create innovative slots that will stand out from the hundreds of games available today.
