How Do Online Slots Decide Who Wins?

Online slots are some of the most popular casino games, usually because they can be relatively easy to play!

You simply place your bet, hit Spin, and wait for the reels to stop. If you land a winning combination, you can receive a possible payout according to the game’s paytable.

The process may sound straightforward, but there’s a lot going on behind the reels to determine the slot’s spin outcomes. Continue reading this Wizard Slots blog post to discover how online slots decide who wins!

Can You Actually Win On Online Slots?

Yes, it is possible to win on online slots. 

However, slots are random games of chance, and any winnings can never be guaranteed. 

Slots can offer players a theoretical payout percentage, also known as the Return to Player (RTP rate). This percentage can differ between each game and may help players determine which slot game could be a good fit for them. There are also some other factors players may consider, such as volatility, but we’ll discuss these in more detail below.


The RTP is a theoretical value that can be used to indicate how much a slot game is likely to reward players after playing for a long time. 

The average RTP typically ranges from 95% to 97%. However, you might find games with RTPs of 90% or lower. For instance, a slot that offers a 93% RTP means that, theoretically, it could pay back £93 for every £100 wagered.

But remember, slots are random, and a higher RTP doesn’t always mean better possible returns. You could win more than the indicated RTP, less, or nothing at all.

RTP rates can potentially be a useful tool when deciding which slot games to play. Some players may prefer a high-potential RTP game, while others may look for slots that offer a lower RTP rate. It all comes down to the player’s preference.

Consider The Volatility

RTP and volatility usually go hand in hand. Volatility is a theoretical measure of the frequency and size of possible winnings in a slot game. So, developers can typically classify slots as low, medium, or high volatility.

High-volatility slots have the potential to trigger a sizable payout after a long period of playing time. Conversely, low-volatility slots might trigger small possible wins more regularly. 

Some players may prefer high volatility slots because of the max win potential. Others might prefer medium or low-volatility slots. Like RTP, volatility does not offer any guarantees. Instead, both volatility and RTP can act as a guide to help you choose a game you think might best suit you.

How Do Online Slots Decide Who Wins?

Online slots decide who wins through a complex mathematical algorithm called the Random Number Generator (RNG). Generally, RNGs use a seed number to generate millions of values each second. These random number sequences are then used to determine the slots’ outcomes. As a result, they are completely unpredictable and can make slot games fair for all players.

Is There An Algorithm For Winning Online Slots?

No, there is no algorithm for winning online slots. Online slots are games of chance, so every outcome is unpredictable. They can achieve their randomness via the Random Number Generator.

RNGs are great because they ensure every outcome is fair and unpredictable. In addition, it’s impossible to beat RNGs since they can generate millions of sequences every second, even when a slot isn’t being played!

There is no algorithm for winning online slots because they’re games of chance. Slots are designed as an outlet for fun and not to make a potential profit. Remember to always gamble responsibly.

Can You Tell When A Slot Machine Will Hit?

You cannot tell when a slot machine will hit because it’s a random game of chance. Slots produce random outcomes because they use a Random Number Generator. RNGs use their complex mathematical algorithm to produce unknown results every time.

Some spins might appear to produce the same results or patterns, but remember that the values constantly change. Therefore, there is no discernible pattern but, instead, a mere coincidence.

Does It Matter What Time Of The Day You Play Slots?

No, slots always produce random results, so it doesn’t matter what time of the day you play slots. Some believe that slots produce more wins in the morning and at night. However, they most likely fail to account for the fact that slots are random games of chance - they’re unpredictable.


Online slots are always random due to the RNG, and any winnings can never be guaranteed. If you enjoy playing online slot games, we have a vast collection of online slots worth browsing at Wizard Slots!
