What are High Volatility Slots?

Slot volatility or variance refers to the risk involved in a game. High-volatility slot machines involve three main factors: high risk, low win frequency, and high payout value. They are the reverse of low volatility slots that involve low risk and pay more often, albeit the small returns.

With high variance slots, the returns are enormous and sometimes have progressive jackpots. But it calls for your patience since hitting the winning combination might take time, explaining the high risk involved.

Guide to Slots Volatility: The 3 Basic Types

As mentioned, slot variance can be defined in three main aspects: the risk taken in a slot game, hit frequency, and value of payouts. You will find three main slot game volatility levels, and the table below summarizes them:

VolatilityRiskHit FrequencyPayout Value

High Volatility Slots

High-volatility games are packaged with high-level risk, thrill, and excitement. They are perfect for experienced players with a huge budget or those motivated to grab large wins and are willing to go through the rough patches before they win big on the prizes. You expect a low hit frequency whenever you play high volatility slots, but a huge win awaits when you line up the winning symbols on a payline. Most Megaways and progressive jackpot slots fall into this category.

Medium Volatility Slots

Medium variance slots give the best of both worlds. There is no high risk or low risk involved, and as you would expect in such, the hit frequency is average, with decent winnings. You can expect games with moderate jackpots, with others having plenty of bonus features on their base games. The medium variance slots are further subdivided into two: low-medium and high-medium.

Low Volatility Slots

Low-variance slot games are the opposite of high-volatility slots. There is low risk involved, and as a result, the payout value is low. But the highlight is that the hit frequency is high, making them perfect options for beginners or players looking to have fun and longer gaming sessions with a tight budget. Some low variance slot games may have jackpots, but the grand prizes are prized lowly, averaging 100x your bet.

High vs Low Volatility Slot Machines

Having provided a review on each type above, we provide a table that helps you distinguish a high and low volatility slot:

Involve high riskInvolve low risk
Payout occasionallyPayout frequently
Big winsLow wins
Require a big budgetRequire any budget
Perfect for experienced bettorsPerfect for beginners

Who Should Stick with High-Volatility Online Slots?

As we have stated in our slots guide, not every slot player can play a high-variance game. These games will require high risk and have a low hit frequency. Therefore, these high-volatility games are perfect for experienced players who understand the risk involved in games and are willing to go through with it at the expense of a massive payout, sometimes a jackpot.

Another group of players perfect for playing high volatility slots is those with a large bankroll that can sustain them during long dry spells. Like the first group, these players should be willing to take the high risk for a big reward.

Should I Still Consider the Slots RTP?

Besides volatility, the return to player (RTP) percentage is another common aspect to consider while playing a slot game. RTP refers to the amount the casino game pays back as profit to a player. The metric is expressed in percentages. For example, the Big Bass Bonanza slot machine has an RTP of 96.71%. It means a $100 bet returns $96.71 in profits. A slot with an RTP above 96% is generally a high RTP slot machine.

To answer the question, you should still consider RTP while playing high-volatility slots. A combination of high RTP and high volatility slots is a perfect recipe for big and profitable wins.

How You Can Discover Your Slots Volatility

You can use a few ways to discover your game’s volatility. They are:

  • Checking the paytable: Some slot developers and online casino sites are generous with information on their games, allowing you to find information like volatility on the paytable.
  • Trying the game: You can launch the game in the free-play mode and grade the hit frequencies and value of payouts to determine the volatility.
  • Research: You can also read reviews online to find the volatility before playing slots, like this guide.


  • Is high volatility in slot games good?

    Volatility will range from high to low. When you play high volatility slots, you will win less often but record big wins on the prizes.

  • Which slots have high volatility?
    Most slot developers, like Pragmatic Play, NetEnt, Big Time Gaming, and Relax Gaming, have high-volatility slots. They include Big Bass Bonanza, Immortal Romance, Mercy of the Gods, and Raging Rhino Megaways.
  • What does volatility mean in slots?
    Volatility refers to the risk involved in slot games. While you can lose a bet on all games, some are more predictable. You risk losing more as you play high-volatility slots than slots with low volatility.
  • Do high variance slots pay more?
    You are likely to have a big win on a high volatility slot, albeit less often. It contrasts with low volatility slots that pay out frequently, albeit the small wins.
