What are High-Volatility Slots?

15 February 2023

You will hardly find a casino site in the United Kingdom without high volatility slots, and the reason is simple. Though punters enjoy playing for fun, no one would say “no” to a big win!

Most times, players believe progressive jackpots and prize pools have the highest payouts. However, these games lead to lower wins over time. With high-volatility online slots, you receive big wins by forming a combination of similar symbols rather than waiting for winnings accumulated over rounds.

The best gambling sites boast a variety of high-variance slots with mind-boggling payouts. This article highlights the best options to make playing slots truly exciting.

What is a High-Volatility slot?

Volatility, also referred to as variance, gives players an idea of the size of the winnings and their frequency at a slot game. In essence, this term refers to how much risk comes with playing online slots for real money.

It is crucial to understand the concept of volatility before attempting high variance slot machines. These thrilling casino games boast large jackpots and multipliers, guaranteeing players incredible winnings after landing similar symbols on the reels. However, the payouts are less frequent. If you love thrilling slot titles but don’t have time for small wins, go for those with high variance!

How to Determine an Online Slot’s Volatility

While many popular online slot machines display their volatility, there are still a few that hide this information. Therefore, it is crucial to understand how to determine the volatility of these games. You need a good knowledge of mathematics to calculate the exact value, which might be demanding. Instead, you can consider a few factors to ascertain a slot’s volatility.

Before choosing a slot game, you must check the paytable for the values of its symbols. By comparing the payout differences between the four and five-of-a-kind symbols, it is possible to predict a game’s volatility. For high-variance slots, the gap is usually quite significant. Also, you should assess the maximum bets, as these games allow affordable wagers despite the winnings sizes. This makes it an interesting prospect for new and seasoned players.

Rewards are an essential feature of the best high-volatility casino games, so punters must confirm the available bonus features and jackpot prizes. You will find several lucrative options at the latest variations by top software providers. Playing in the demo mode is a good way to explore various games for free while noting the frequency and size of their payouts. Now, you have all the information needed to determine a volatile online slot.

How to Choose the Right High-Volatility Slot Machines

Choosing the perfect high volatility slot can be quite a chore, especially for newbies. Therefore, UK gamblers must understand the criteria that determine the best options. Learn how to choose high-volatility slot games below:


RTP is the portion of a players’ wagers that a casino pays back as winnings over time. You must know the return-to-player percentage of a slot game before placing any wagers. Titles with values above 97% are considered high RTP slots, which also guarantees a low house edge.
