Tombstone RIP High Variance Slot Game

If you have ever taken the time to look beyond the surface of any video slot game by reading one of the many game profiles published on review websites or on slot developer websites then you will more than likely have come across the term ‘variance’ or ‘volatility’, expressed as high or low.

Volatility is a key factor in affecting your experience when playing an online slot. But what does it mean and why is it important to understand when choosing your next slot game? In this guide we will explain what variance is and how it impacts the payouts as you spin the reels. Further down the page we will also pick 5 slot games with high variance and 5 with low variance to try next time you play at any real money casino in Canada.


Slot variance is a measure of deviation away from the expected payout rate or RTP of a game. A low variance slot will deviate from its advertised RTP to only a small degree whereas a high variance slot will deviate greatly.

In practice this means that low variance slots typically pay out more frequently but in smaller amounts. High variance slots pays out less frequently, but in bigger amounts. This makes high variance slots higher risk but with bigger rewards.

It’s important to remember that, as with all information relating to the maths model of a slot game (RTP, variance and win frequency), these are theoretical measurements that describe the average behaviour of a game. We don’t always get the same experience. Some of us get very lucky and some very unlucky!


The important thing to understand about variance is that it will have a big impact on your game experience. And you should take the time to decide which kind of slots player you are which kind of games you like. To help you, here is a rundown of the characteristics of each.

Low Variance Slot Characteristics 

  • Low deviation from the advertised RTP
  • Regular, smaller wins
  • Greater odds of hitting a winning spin each time
  • Lower risk gameplay
  • Even distribution of wins
  • Can be played with a small balance as the regular wins keep topping it up
