Random Number Generator Determines the Outcome

A sophisticated software algorithm called a Random Number Generator (RNG) lies at the heart of all online slot games, ensuring fairness and totally random outcomes.

This type of technology guarantees that every spin of the reels is entirely independent, giving players a fair chance to land a win.

Licensed online casinos in the US are regulated by local gambling authorities (different for every state), overseeing the RNG system’s implementation. This plays a significant role in helping players feel safe and trust the casino.

The RNG is a kind of engine behind the scenes, generating thousands of random numbers per second to ensure that outcomes are unpredictable and devoid of any patterns, stopping every attempt of manipulation and ensuring a level playing field for all gambling enthusiasts.

We should also demystify the theory of “cold” and “hot” streaks, as the player has an equal chance of landing a big win on every spin, despite the outcomes in the recent past.

To ensure their RNG numbers are correct and fair, licensed online casinos in the US undergo rigorous testing and certification processes. This sense of fairness and the thrill of unknown outcomes make online slots the most popular choice for new and seasoned casino players.

Understanding RTP (Return To Player) in Online Slots

Return To Player (RTP) is a term with significant importance in the world of online slots. It’s a crucial factor in determining a player’s potential payouts and chances to win in slot games.

It is a number that always allows the house to maintain a certain edge over players while ensuring transparency and fairness.

The most simplified explanation of RTP is a percentage of wagered money that a specific slot game is programmed to pay back to players over time. The info you can find online about the RTP of specific slot games is based on a calculation over a large number of spins, and it might vary slightly.

Online casinos rarely publicly announce their games’ RTP, but a simple Google search can help you find the desired numbers.

Every online slot has a different RTP, usually 92% to 97%. The ones with lower percentages probably have high potential jackpots and a lower frequency of wins, while higher RTP slots offer more frequent wins and lower jackpots.

Let us take an example to illustrate how RTP works. If a slot game has an RTP of 95%, players can expect to receive $95 back on average for every $100 they wager in the long run.

Of course, this is not an excellent indicator to calculate how much you can win and lose short term, as the outcome deviates significantly from the expected average.

Volatility Is Another Important Factor

When exploring online slots, another critical aspect is volatility. Volatility, also known as variance and refers to the frequency and magnitude of potential wins.

Low volatility slots offer more frequent but smaller wins, providing a steady gameplay experience. On the other hand, high volatility slots are characterized by less frequent wins but with the potential for larger payouts.

The choice between low or high-volatility slots depends on individual preferences and playing style. Players seeking excitement and the possibility of hitting substantial jackpots might opt for high-volatility slots, while those who prefer more consistent, smaller wins might lean toward low-volatility options.

Understanding the volatility of online slot games allows players to tailor their gaming experience according to their tolerance and desired level of excitement.


Hopefully, this article helped you better understand how online slot games work. We explored the role of the RNG in ensuring fair outcomes, the significance of RTP in determining potential payouts, and the impact of volatility on the gaming experience.
