High Variance Slots: Our Ultimate Guide With Tips, Recommendations, Reviews And More!

High Variance Slots

For adventurous players and thrill-seekers, high variance slots are an ideal choice. Slots tend to come in 3 key types: low variance slots, medium variance slots and high variance slots.

Variance, also known as volatility, is the average measure of how often you'll win when playing slots.

So, some slot machine games will have low variance, which means they're more likely to pay out, while others are medium and some are high variance slots.

For beginner slot players, you might want to consider exploring low variance slots to learn the rules before advancing to a high variance game.

If you're eager to jump right in and get the potential to win the maximum payout on some big money games, then find out more about playing high variance slots.

What defines high variance slots?

A high variance slot is a slot machine game with high volatility. That means that the game pays out less frequently than low volatility slots, but that when it does, the maximum bonus is higher.

So, you can get a major windfall from playing high variance online slot games, but you also run more of a risk.

When you play high variance slots, you have more of a risk of losing your money but also a better chance of getting big wins and earning the max cash available on the game.

The risk needs to be weighed up against the reward, so you can work out whether you're willing to try your luck and, potentially, win big.

Usually, high variance slot games don't offer many small prizes, so you can get big wins, but you take a major risk.

You'll need to place a larger bet when you play a high volatility slot machine online, but you have the potential to win more money, hit more high-paying symbols and get better returns from the winning combinations you land on.

It's always important to play responsibly when you're online gambling in any form. So, if you're new to slot games or don't want to take a risk, you might want to avoid high variance slots and consider choosing low variance slots instead.

You can start with the lowest variance options, then move onto higher variance slots and slowly progress as you play slots more often.

When you're looking for your new favourite high variance slots, you need to check the return to player, or RTP, as this score is what determines the amount of money paid back to players.

The higher the percentage of money paid back, the lower the volatility of the slot game. So, high volatility slots have a lower RTP.

How to play games on high volatility slot casinos

Now you've chosen the ideal high variance slot platform and taken every precaution necessary, it's time for the fun part: playing!

To get started, you'll need to:

  • Sign up for the site and prove your identity

  • Verify your account

  • Put some money on your account to play with

  • Choose the best high variance slots on the site and start playing!

It's as easy as that! 

Bonuses to watch out for on high variance casino sites

 Many online gaming platforms offer casino bonuses to entice players and keep you playing on their site. 

Some of the most common bonus features to watch out for when playing high volatility slots are: 

  • Free spins: Many casinos give free spins to players, so you effectively get another go without having to place another bet. There are sometimes ways to get further free spins, such as by leaving a review on social media, so check out all the ways you can get free spins on every casino you try out

  • Welcome Bonuses: Some casinos give welcome bonuses to new players, so it's worth shopping around to see what you can get. These bonuses only come along when you create a new account, and because you have to prove your identity, it's not an option to make multiple accounts! 

  • No Deposit Bonuses: While they are rare, some casinos offer no deposit bonuses, which means you don't even have to spend your own money to get free spins. Make sure you read the terms carefully, so you know what you're in for!

Many sites offer a range of bonuses to new and existing players, so make sure you explore all your options and take advantage of every bonus feature you're eligible for. 

In-game bonuses to look out for

As well as online casino bonuses, there are also bonuses in the games themselves that can help you make the most of your money. 

These include:

  • A Bonus game

  • Bonus spins 

  • Wild symbols

  • A free spins round 

  • Expanding wilds 

These bonus features aren't guaranteed, but they're common in many slot games with high volatility, so look out for them and make the most of them if they're available. 

Common terms and conditions for high volatility slot games

Every online gaming platform has its own Terms and Conditions, which it is obliged to share clearly with players.

Some common T&Cs you might see on sites that offer high volatility slots are:

  • Max Bonus: You might be limited to a maximum bonus you can receive

  • Bonus Limitations: Bonus funds contribute to your winnings, but you might not be able to use them on certain things, such as to pay for a particular game or to buy extra spins

  • Betting Requirements: You might have to bet a specific amount of your own cash before you can play 

Before you start using a new online casino, you need to make sure that you check the T&Cs and are happy with them. 

Why choose a high variance slot game?

If you love taking risks and are an experienced slot machine player, then high variance slots can be the perfect solution for you.

They're fun, and you've got the potential to win big money that you don't have if you play less volatile slot machines online. 

As long as you play responsibly and stop when you've had enough, you can have great fun and potentially win big with high variance slots. 

Are high variance slots worth it?

High variance slots offer many benefits to players. The main one is that you can get massive wins and earn extra cash if you're lucky.

Some of the other benefits of high variance slots include:

  • There's a massive range of high RTP slots to choose from

  • Playing high variance slots gives you a rush

  • There are usually great features in high volatility slots like an exciting free spins bonus, a free spins bonus round, high value wild symbols and more

  • You can learn more about the casino mentality by playing high stakes slots and use this in your other investment ventures

These benefits mean that you can have fun playing online slots and potentially come away with a big win if you're willing to take the risk.

Low variance VS high variance slots: what’s best for me?

When you're deciding between high variance and low variance games, you should ask yourself the following questions: 

  • What's the minimum bet I'm willing to place?

  • What's the maximum bet I'm willing to place?

  • How much risk am I willing to take?

  • Do I get bonus features such as free spins?

  • Does this specific game look fun?

Once you know the answers, you can work out which option is best for you. If you're unsure, consider playing a demo version for free first to learn more about the game and feel more confident before you start gambling with real money. 

Deposit and withdrawal options at high variance slots sites

When you're playing high volatility slots online, there are many ways you can pay in your money and withdraw your winnings. 

As of 2020, the UK Gambling Commission banned credit card payments on online gaming sites, but there are still plenty of other ways to pay. 

The main deposit and withdrawal options for online casinos include:

If you're unsure about which method will work best for you, then check out the specific casino you're using. 

The site’s payment page will give you a clear indication of how you can pay and withdraw your winnings.
