There is a world of entertainment that awaits anyone who enters an online casino today. This includes different types of games from the latest online slots to classic table games. And then there is a player favourite known as jackpot slots, which are in a game category of their own.

In this guide, we take a look at how frequently jackpot slots pay out and how to read the winning frequency of Jackpot Slots or Games.

What are jackpot slots?

These are a form of online casino games that award bigger wins than your average slots. With each game, you have the opportunity to win 500x or more of your stake. Meanwhile, with standard games, you can win less than 100x your total bet as a fixed jackpot amount.

There are three different jackpot variants to keep in mind:

Fixed/standalone jackpots – not linked to other games or machines;
In-house progressive jackpots – jackpot games that are generated by linking the same game to itself within the online casino;
Network progressives – the same game is linked across a number of online casinos, increasing the jackpot potential.

It’s not a "one size fits all" when it comes to jackpot games

When it comes to jackpot games, you will quickly come to understand that there are many options for all types of players. The main reason is that there is a wide range of jackpot and progressive jackpot games (learn more with our progressive jackpot guide) and none of them is the same.

There are many things to take into consideration when choosing each of these games. This includes the Random Number Generator, hit frequency and volatility. One thing to keep in mind is that winning is always random and a matter of chance. Whether you’re playing a jackpot slot or a table game with a generous jackpot attached, the Random Number Generator determines the outcome.

While there are some tips and tricks to help increase your winning odds, there’s no surefire way of beating the odds. Winning a jackpot is all about luck.

Key stats behind jackpot games payouts

There are a few factors that contribute to the frequency with which a Jackpot Game will payout. This includes the RTP, volatility and hit rate. Let's get a closer look and get a better understanding.

Pick the right volatility

It’s easy to confuse the hit frequency with the volatility or variance of a game. The volatility is the likelihood that the slot or game will payout and the size of these rewards.

Generally, games will have low, medium, or high volatility, and each class has different payout opportunities.

Low volatility: This means there is a chance for small, frequent payouts.
Medium volatility: This means the wins are about average in terms of size and frequency.
High volatility: Wins don’t come around too often, but they can be quite sizeable.

In essence, the slot volatility will give you a sneak preview of how the slot will pay, while the hit frequency will give you more insight into the overall average payouts. These stats need to be combined as low volatility slots will have a high hit rate, but the payouts will be smaller.

Which, in essence, won’t be what you’ll be looking for if you’re trying to hit jackpot wins.

How frequently do wins occur?

As stated, the hit frequency also significantly determines how often a slot or jackpot game pays out. It will indicate how often you will win, even if it is a small win in a single spin. If a slot has a 23% win frequency, then it shows that it is bound to award one or more payouts on about 23% of the spins.

This figure isn’t always made available, which means there will be times when you have to guess the percentage. You can guess based on the average slope,t, which tends to feature a hit frequency of between 20% and 25%. This essentially means you can win 1 in 5 times or 1 in 4 times.

Keep in mind that this is not always the same for mobile slots or jackpot games, as mobile variants often have a 15% or lower hit rate. Then you will always have slots that feature a hit rate of 30% or higher.

Understanding Return to Player (RTP)

The Return to Player Percentage or RTP is a theoretical percentage of returns you can expect when playing a game. However, if a game has an RTP of 96.9%, that means you can expect to lose nearly $3 for every $100 you play.

With RTP, you also need to keep in mind that the RTP is based on the overall lifespan of the game instead of singular gameplay. Meaning you can play 100 spins and not win once, while another player might take one spin and win instantly. The RTP is tailored to the game and not individual sessions.

It’s always best to choose a game with a higher RTP as it increases the winning odds and decreases the house edge.

Hot and cold fallacy

One thing many eager jackpot players tend to believe in is the “hot and cold” prediction of Slots and Other Games, including Jackpot Games.

This hot-and-cold fallacy is, in essence, a ‘tell-tale’ of when a game is likely to produce wins and when it is best to be avoided.

The idea behind this fallacy is simple: a game is “cold” if it’s been giving mostly losses, and “hot” if it’s about to hit a big win after a dry spell. But these are just guesses, not facts. There’s no reliable way to predict outcomes based on this.

You might get lucky, but the priority would be to place your focus on RTP, Volatility and Hit Frequency when choosing your game instead of whether or not it is considered a hot or cold slot at the moment.

Tips to play like a pro

Playing jackpot games successfully isn’t just about luck; it’s also about making smart choices and developing good habits. Here are some essential tips to help you play like a pro and maximise your chances of winning:

Choose the right casino by reading thorough online casino reviews!
Take advantage of the free play/ demo mode and practice without risk.
Bet enough to be eligible for jackpot wins.
Pick your games carefully, based on RTP, volatility and your preferences.
Stick to your budget to keep your gameplay responsible.
Watch the RTP to find games with better odds.
Read reviews on the game you choose.

Play responsibly

With jackpot games, it can be quite alluring to burn through your bankroll as you spin for potentially life-changing wins. However, as you often have to bet the maximum on the winning paylines in order to stand a chance of winning, it’s important to remain in control.

Before you start playing, you need to decide how you want to play, how long you want to play and how much you are willing to lose. Top recommended online casinos have a range of responsible gambling tools available to assist in responsible gameplay in this manner. Stick to your budget and never chase your losses!

This ensures you can enjoy the game at the moment and helps you rein it back in when needed. This includes setting up deposit limits, loss limits, and session limits. These account limits can be especially helpful when you’re playing big-win games such as Progressive Jackpot Slots and Table Games.
