RNG Technology – How Online Slots Work

Did you know that the spinning reels on an online slot are just for show? That’s right—the moment you click “spin,” the outcome is chosen instantly and completely at random. But that’s not the whole story. In fact, as soon as you load an online slot game, the system starts generating potential outcomes every millisecond, long before you even start playing. This ensures that no player can predict or influence the results.

The Myth of “Hot” and “Cold” Slot Games

At Play Some Slots, we’ve tested countless games, and we can confidently say that there’s no way to “crack” or predict the code behind a slot’s outcome. Random Number Generator (RNG) technology is so complex that it’s impossible for anyone, including us, to predict when a game is “due” for a win. So, if someone tries to tell you a slot is “hot” or “cold,” feel free to call that out as nonsense. The outcome is always random.

How RNG Technology Works

At the heart of online slot machines lies a sophisticated algorithm, a string of complex mathematical calculations that determine the outcome of each spin. This algorithm generates random results to ensure fair play. While most people won’t understand the intricacies of this technology (and you don’t need to), it’s important to know that it can be tested for accuracy by regulatory bodies.

Licensing authorities, such as Malta's Lotteries and Gaming Authority (LGA) and other regulatory bodies, regularly test these algorithms to ensure fairness. These tests ensure that the game results are truly random and that players are not being cheated.

Understanding RNG: A Simplified Explanation

To help you better understand how RNG technology works, imagine physically opening up a classic slot machine in a Vegas casino and laying out all the reels. On a physical slot, each reel typically has around 22 stops—some marked with symbols, others just blank spaces.

In an online slot, however, the process is a bit different. If you could “open up” an online slot, you’d find 100 or more virtual stops per reel. This doesn’t mean your chances of winning are lower, though. It just means there are more possibilities for the RNG to choose from, especially to accommodate for features like wild symbols and bonus icons, which aren’t typically found on physical slots.

Why RNG Technology Matters

The random nature of RNG technology ensures that:

  • Every spin is independent and not influenced by previous results.
  • The game remains fair and unbiased for all players.
  • Patterns or predictability are impossible, keeping the game purely based on chance.

For players, this means that no strategy, trick, or timing will influence the outcome. Your best bet is to enjoy the game responsibly and understand that luck plays the only role in determining your results.


FAQs About RNG Technology in Online Slots

What is RNG technology?
RNG (Random Number Generator) is a software algorithm used in online slots to generate random outcomes for every spin, ensuring fairness and unpredictability.

Can RNG be manipulated?
No, RNG technology is designed to be unpredictable and secure. It is tested regularly by independent authorities to ensure fairness, and no player or casino can influence the results.

Do online slots have patterns?
No, online slots do not have patterns. Every spin is independent, and RNG technology ensures that no player can predict or manipulate the outcome.

Is there a way to win by timing your spins?
No, since the results are generated randomly by the RNG the moment you click “spin,” timing your play will not affect the outcome.

Are online slots fair?
Yes, licensed online slots are tested regularly by regulatory authorities to ensure that the RNG is functioning correctly, providing fair and random results for all players.


By understanding how RNG technology works, you can better enjoy online slots knowing that every outcome is truly random and based on chance. Remember, there’s no way to predict or influence the results, so play responsibly and have fun!
