How Are Jackpot Slots Different to Regular Slots?

There are a few significant differences when comparing jackpot slots to regular online slots. First of all, as mentioned previously, you can typically win more on a jackpot slot. This is because these jackpots regularly reach the millions and are paid out to one fortunate player.

Secondly, the RTP is usually lower on a jackpot slot. In short, the RTP determines how much a slot pays back over the long term. So, the closer to 100% the RTP, the more likely it is to payout more frequently. If you’d like to know more, then read our article that covers slot RTPs now.

Another point to mention is that you will most likely come across extra features like Jackpot Bonus Games or Jackpot Wheels when playing a Jackpot slot.

Regular VS Jackpot Slots – Which is the Better Option?

When picking an online slot to play, it comes down to your personal preferences and what you’re looking for in your gaming session. So here are some key points to consider:

What Slots Suit Your Style Most?

Each online slot game ultimately has its own style, and that’s what makes them so great. So whether you like to play the classic pay line slots, Cluster slots or ever-popular Megaways slot games, there is a game waiting to suit you.

There are hundreds of themed slot games out there on the market. This can include things like your favourite TV show to your favourite holiday season. When you come across a game that you love, it will take your gambling experience up to a whole other level.

How Much Are You Hoping to Win?

It is essential to realise that not all online slots offer a jackpot prize. However, they all clearly state the maximum potential of the game, which allows you to see if the game is worth it to you. If you are looking for a win in the millions, then big money Jackpot slots are undoubtedly the ones for you. On the other hand, some regular online slots can still payout insane amounts of money with a lucky spin on the reels.

We recommend reading over our Top 10 Online Slots with the Biggest Win Potential article. This post gives you a rundown of the slots that offer the highest maximum win potential and where to play them.

What Features Do You Like Most?

You will quickly realise that every game offers something different. For example, some Jackpot slots don’t have free spins but may instead offer a pick and click bonus game. As always, we recommend you read the rules of the game and, if possible, play the game for free before spending your own money to see what games feel right for you.

Types of Jackpots

There isn’t only one type of jackpot on offer. Although games offer many different kinds, you’ll find the most popular types of jackpots below.


Progressive Jackpots are the most common prize pools that you think of when you think jackpots. These prize pools grow from a percentage of players bets every time they spin the reels or bet on their favourite game. This means that the more players gamble on a particular slot, the higher the reward will be. These Progressive Jackpots regularly reach over the £10 million mark and award one lucky player with a life-changing amount of money.

Another interesting fact about progressive jackpot games is there is commonly more than one jackpot to be won. These come in different sized packages.

  • Mini Progressive starts at £10
  • Minor Progressive starts at £100
  • Major progressive starts at £10,000
  • Mega Progressive starts at £1,000,000

Once a Progressive Jackpot has been won, the prize fund will automatically reset to the minimum amount.

One of the most popular slots series that offer progressive jackpots is the Mega Moolah series of games. For example, 7 out of the top 10 biggest online slots wins have come from Mega Moolah. One of the latest wins is a player who won £17.3 million on Absolootly Mad: Mega Moolah on 27th April 2021!


Hourly Jackpot Slots give players the chance to win a jackpot every single hour of every day! So, there is always a guaranteed winner within each hour. The hourly jackpots typically start at a lower amount. However, these progressive jackpots mount up until one lucky player walks away with the whole lot. Red Tiger is famous for its Hourly and Daily jackpots. We have a complete list of games that offer the hourly jackpot on our Hourly Jackpot Slots page. It’s important to note that the Hourly jackpots run across all Red Tiger games that offer them, so you can play many games and still be in with the chance to win!


Daily Jackpot Slots work similarly to Hourly Jackpot Slots. So be in for the chance to win a jackpot every single day! The great thing about Daily Jackpots is that they offer more significant amounts of money than their Hourly counterparts. In addition, someone is guaranteed to win this jackpot every single day.


Fixed Jackpots are precisely what they say on the tin. In short, Fixed Jackpots have a set value that payout, which does not change regardless of bet size or how many players are playing that game. Fixed Jackpots typically have a payout amount of between 1,000x to 10,000x of the players bet. Winning a Fixed Jackpot consists of landing the rarest symbol or jackpot symbol on the reels and then most likely entering a Jackpot Bonus Game.

Which Providers Host Jackpot Slots

Most jackpots are not exclusive to specific casinos. Slot developers also have their own jackpots that persist across their games! Some of these jackpots are tied to promotions that last for a certain period.

Can You Win Big Money on Jackpot Slots?

Yes, you can win massive amounts of money on Jackpot slots. As we have already mentioned, most online jackpot slots have prizes in the millions. Landing a win like that would be life-changing to anyone. Besides the jackpot funds, these volatile games also have high maximum win potential in the base game than many regular slot games on the internet.

As a side note, with the RTP being a smaller percentage on jackpot slots, they typically don’t payout as frequently. Unfortunately, this means your budget might not stretch as far as you would ideally like it to.

First-Ever Big Money Jackpot Game.

The first-ever Jackpot slot was Megabucks, released by IGT in 1986. Megabucks was the very first slot to offer a progressive jackpot and was revolutionary on launch. Megabucks is a typical 3 reel slot that starts its jackpot off at $10 million or roughly £7.4 million.

First Online Jackpot Game

Cash Splash Slot Image

Soon after the first land-based slot was released, the first online jackpot slot, Cash Splash from Microgaming, was created in 1998. Cash Splash provided medium to high payouts and came with massive jackpot prizes.

Microgaming has gone from strength to strength with its jackpot series of slots. Mega Moolah was released in 2012 and quickly became a fan favourite.

Do Casinos Host Their Own Jackpots

As a matter of fact, yes. LeoVegas have recently introduced four massive progressive jackpots known as LeoJackpot, worth over £4,500,000! You could win the jackpots by playing some super popular games.

To participate in the LeoJackpot, you must opt-in. By doing so, you will pay £0.09 on each spin, which will allow you to be in with a chance of spinning the Jackpot wheel.

Can Big Money Jackpot Slots Be Rigged?

If you are playing on a legitimate online casino, then the answer is never. To safeguard yourself and your money, check out our Are Online Casinos Rigged? This blog will give you hints, tips and tricks to know what casinos you can trust.

What Are the Odds of Winning a Jackpot?

The chances of you hitting any major jackpot start at 50 to 100 million to one. So, it’s not highly likely that you will hit the jackpot. However, a few things to look out for, like RTP and slot variance, as this can sway things your way very slightly. The 50 to 100 million to one is average odds. For some jackpot providers, this amount can reach heights of 600 million to one likelihood.

Can I Increase My Chances of Winning a Jackpot?

Yes! The best thing you can do to increase your chances of winning a jackpot is to bet higher. Progressive jackpots typically make you aware in their game rules that you are more likely to win the jackpot if your bet is higher. Therefore, higher bets increase your odds of winning.

Another way to increase your chances is to play the hourly or daily jackpots on offer. These games must payout on time, and if you are there playing, there is every chance it could be you.

Can You Win a jackpot Whilst Playing with Bonus Money?

Unfortunately, most online casinos do not allow you to play jackpot games with bonus money. This is because bonus money is technically the casino giving you money until you wager it. So always read the terms and conditions to see if you can play jackpot games with any bonus money.

In addition, you may notice that in games where you are not allowed to wager when you enter the game, the only balance you have is your real money balance and no bonus funds.

Do You Need to Bet the Maximum Amount to Win a Jackpot?

You do not need to bet the maximum amount in order to win a Jackpot, progressive or not. Betting higher does increase your chances of hitting a progressive jackpot. However, it is not necessary. Players have won millions before betting only £1.00. This is excellent news for jackpot hunters as you can spin for longer on lower bets and still have a chance at any jackpots on offer.

Can You Withdraw All Jackpot Winnings at Once?

Most online casinos have a maximum amount that you can withdraw per day, week and month. So, if you do hit a jackpot win, you may be withdrawing slow amounts over time. Some casinos have it in their terms and conditions to pay you the total amount in equal instalments. To avoid disappointment, it’s always advisable to read the casino’s terms and conditions surrounding jackpot games and withdraw money before playing.

Can Jackpots Only be Found on Slot Games?

No! Jackpots are found on a whole host of live casino games as well. That’s the great thing about online casinos. Jackpots can be spread across many games, regardless of category, and can be won by any player.

One example of this is LeoVegas’ Live Roulette, where they have their LeoJackpot on offer, which can see you walk away with over £7,000,000 in prizes!

When you enter the game, always check whether or not a jackpot is on offer, as it’s usually well advertised.
