Types of Slot Variances

Here’s a quick look at the main differences between low, medium and high variance slots. It should give you a clearer idea of the type of slot that’s right for you.

Low Variance Slots

Unlike high variance online slots, low variance slots are games where wins come in very regularly, but at the same time, big wins are unlikely. This is why low variance slot games are best suited to beginner slot players. You can read more about them in our article – just click the low variance slots link at the beginning of this paragraph. 

The low variance slot Starburst

Medium Variance Slots

Medium variance slots are, you guessed it, a compromise between low and high variance slots. These slots produce plenty of low and mid-sized wins throughout and there is even a chance of a big win as well. Playing medium variance slots are a good way for you to still win a big sum without having to risk too much of your bankroll. The question is, how big of a risk do you want to take?

The medium variance slot Rainbow Riches Pots of Gold

High Variance Slots

At the other end of the spectrum are high variance slots. In order to win on these slots you need to play for a pretty long time before a win comes. But when a win does hit, the sum is usually much bigger. These slots tend to appeal to ‘high rollers’ and those players who are looking for big wins. For example, almost all Megaways Slots are high in variance. It’s important to remember that high variance is not the same as a high return to player (RTP). While high variance slots might be described as more ‘risky’, the RTP (return-to-player percentage over time) can be the same as a low variance slot – so always look out for the RTP on a slot game before playing.

Many new slot sites will look to host high variance slot games due to their popularity.

High Variance Slots FAQs

High variance slots are perfect for players who wish to win the big jackpots. The high variance aspect means that for each 'pull' of the slot machine it is unlikely that you will have lots of wins but rather, when you do win, you win big. There is lots of money to be won.
Book of Dead, Game of Thrones and Immortal Romance are three high variance slots that offer the highest return to player (RTP) percentage. Book of Dead players also get the chance to win 50,000x their bet - the highest if any slot game. Basically, you will win more money by playing these three slots. Each of these games can be found in our top 15 list below.
The clue is in the name. High variance slot games are high in variance so the number of wins on these games are less likely, however the rewards for winning make up for this. On the other hand, the number of wins on low variance slot games are extremely high but with that being said, the rewards for winning are therefore quite low. As you can imagine, medium variance slot games are somewhere in between - an average number of wins with a decent payout for each win.
