My top 10 high volatility slots

There are hundreds of high volatility slots at the best online casinos. These games stand out, as they offer sharp graphics, strong return to player (RTP) rates, exciting bonus features, and the chance to win very large prizes.

What is a high volatility slot?

The volatility of an online slot tells you how frequently you’re likely to win. Slots fall into three broad categories:

  • Low volatility slots: These games tend to deliver small, regular wins.
  • Medium volatility slots: Games that offer reasonably frequent wins and the chance to win pretty substantial prizes.
  • High volatility slots: These slots typically deliver large, infrequent wins.

Volatility is also known as variance. High variance slots have a low payout frequency. You can spin the reels multiple times without receiving a payout. However, these games tend to offer large prizes.

If you like racking lots of small, steady wins during a session, it’s best to avoid high volatility slots. Meanwhile, if you like taking risks, and you’re happy to wait patiently for large payouts, high volatile slots can be very rewarding.

Just bear in mind that you’ll typically need a larger bankroll when playing online slots with high variance rates. That will help you ride out any potential losing streaks.

Can high variance slots still have high RTP?

Yes, high variance slots can still have high RTP rates. In fact, some of the slots with the highest RTP percentages are extremely volatile, including Book of 99, Mega Joker, and Codex of Fortune.

What is RTP? It stands for Return to Player. Every online slot has an RTP rate. It tells you the return that a player with average luck can expect from a slot over a prolonged period of time. For example, if the slot has a 95.8% RTP rate, you’ll expect $95.80 back from every $100 wagered if you have average luck. That equates to a 4.2% house edge.

The results are totally random, which means that some players will win, and others will lose. However, choosing a slot with a high RTP rate theoretically increases your chances of success. The average online slot has an RTP of approximately 96%, so try to find games with a higher rate than that. Those are considered higher-paying online slots.

Factors to consider when choosing a high volatility slot machine

The best online casinos offer a wide range of high volatility slots. You can consider five key factors when selecting the slot that’s right for you:

Find a high volatility slot that offers the chance to win huge payouts. You’ll often endure losing streaks when you play these highly volatile games, so you need a compelling incentive to keep spinning. The best high variance slots allow you to chase very large jackpots. For example, Dead or Alive 2 offers a max win 111,111x your bet. Don’t settle for a game that offers a low max win.

How to find an online slot’s volatility

There are a few ways to find an online slot’s volatility:

  • Open an online slot and select the information icon (usually a circled i). Many slot providers display the volatility of the game, along with the RTP rate and the rules, in this section.
  • Visit the provider’s website and search for the game. For example, NetEnt’s site tells you the volatility of every slot.
  • Some online casinos also allow you to filter slots by volatility. For example, you can tap the “Filter” button at bet365 Casino, scroll down to “Volatility,” and select “High.” You’ll then see all the high volatility slots in the portfolio.

Online slots are thoroughly tested to ensure that the displayed volatility rating is accurate. For example, slots from Pragmatic Play have been independently certified by Gaming Laboratories International, Quinel, and Gaming Associates. That guarantees fair, random results, which are in line with the stated RTP percentage and volatility rate.

Are online casino slots more volatile than a retail casino’s?

No. You can find a wide range of low, medium, and high volatility slots at both online casinos and retail casinos. However, online slots tend to have significantly higher RTP rates than physical slot machines.

For example, slot machines on the Las Vegas Strip had an average payout rate of 91.9% in 2024, according to the University of Las Vegas. By contrast, high volatility slots at online casinos have an average RTP of 96%, and some go up to 99%.

How to play high variance online slots for free

Most real money online casinos allow you to play high volatility online slots for free in demo mode. For example, you can tap the “Demo” button to play slots like Cash Eruption and Medusa Megaways for free at DraftKings Casino.

You can also play these slots for free at social and sweepstakes casinos. They give you free coins through various promos, including no-purchase welcome bonuses and daily login bonuses. You can then use your free Gold Coins and Sweeps Coins to play high variance slots.

Another option: you can play wide range of high volatility slots for free in demo mode at PlayUSA, with no need to sign up or download software. Just find a free online slot game and click “Play for Free.” You can find a full list of free slots A-Z.

Finally, you can often play high volatility slots for free by visiting the developer’s website.

Pros and cons of playing slots with high volatility

You can unlock a wide range of benefits by playing high volatility slots, but there are also a few potential drawbacks to consider. Here are both, as I see them:
