Jackpot Slots

Winning a jackpot is the high point of casino gaming, and a plethora of slots ensures that you always have a good selection to choose from. Online jackpot slot machine games often have impressive intrinsic features and offer higher payouts than typical slots.

A jackpot slot is typically won by landing specific jackpot symbols, or the highest paying symbols of a game on the reels. There are several different kinds of jackpot slots available out there – some have fixed payouts, while others have progressive and increasing pots. We cover all of this and a whole lot more throughout this page.

What is a Jackpot Slot?

As briefly touched on above, jackpot slots are those that include a jackpot element in their list of features, meaning that they are some of the most profitable and desirable around. Depending on the game, monstrously big paydays are possible if your luck is in. Even if the bigger wins are decidedly rare, smaller payouts are still possible giving players something to aim for with every spin.

Online slots with jackpots commonly have a progressive element, which is a great way to try and win larger amounts – below is an explanation of these sought-after prizes.

Progressive Jackpots

Progressive jackpots are seen as the holy grail to casino players due to their incredible win potential. Here, the jackpot amount is determined by other players; each time a punter spins the reels and does not win, the prize pot grows. This can often get to huge amounts, especially in the case of networked progressive jackpots, where multiple real money casinos contribute to the fund.

Tips for Playing Progressive Slots

If the thought of playing progressive slots has piqued your interest, then you will be delighted to discover that there are a few things you can do to enhance your experience with these types of titles.

1Spin stake

Some big winners suggest betting the maximum coin amount on spins in order to enhance your chances of landing a progressive jackpot, but you should always play responsibly and keep to a strict budget as if your luck is in then you will be securing a big win regardless of your coin value.

2Luck

Remember that each and every win on a progressive slot is down to luck and you should not read into any other factors such as when the last win was and how big the jackpot is.

3Standalone games

Standalone progressive slots, in contrast to network pooled jackpots, may pay out more often as the prize is determined by that slot alone, but the jackpot is likely to be considerably smaller, so you have to decide which type you prefer.

4Famous wins

Progressive games such as Mega Moolah and Divine Fortune are some of the most iconic slots around and they have resulted in some truly gigantic wins in the past. Even if your odds of winning such a prize are incredibly low, these titles remain extremely popular with players seeking the largest jackpots so you may want to keep this in mind.

These days, jackpot slots are not at all rare, with many new casino game releases coming onto the market with a progressive element – and the list on this page is a testament to this. However, some titles stand out more than others, for either win potential, longevity, or both. Below are our top five picks of progressive slots to play.

How Do Progressive Jackpot Slots Work?

The system used with progressive jackpots is that each time a player places a wager the pot inflates. As players continually bet on the game the pot increases to incredibly high amounts, sometimes running into millions. Once the pot is claimed, it is reset to a base amount, and steadily starts to climb once again. The process keeps repeating itself. The longer the pot lies unclaimed, the higher it rises.

Most progressive slot games run across all mobile platforms, including iOS and Android. The mobile jackpot experience is every bit as good as on a PC. All the thrills and excitement are there, and the potential winnings can rival lottery payouts. Progressive jackpot games filter a tiny percentage of each bet which goes into the pot. These slot games serve the best chance of winning a life-changing payout.

PlayOJO, a Slotsia-recommended casino, has plenty of progressives for you to peruse with some tantalising jackpots.

How to Play Progressive Jackpot Slots

When it comes to progressive jackpots, you will need to wager on all the paylines to stand a chance of winning the jackpot. The higher the coin values wagered, the better the chances of winning the highest payout. Wagering low coin values will also stand a chance of winning a jackpot as long as you bet on all the paylines.

Even though the average payouts of progressives are lower than in some other games, jackpot slots still deliver on multiple fronts – and our list further up this page displays the best casino sites to play them at.

How to Win at Jackpot Slots?

At their simplest, jackpot slots are little different from ordinary slots – you will still need a large dose of luck in order to walk away with the game’s maximum win. However, the exact formula needed to win the biggest prize of them all is unsurprisingly likely to be more convoluted, so you will need to land multiple of the highest-paying symbols across the reels.

The paytable of each game will outline exactly what is required to win, but there are a few things to consider before playing a slot with jackpots to assess how likely a win is:

slotsia

RTP

The return to player rate is displayed as a percentage, and the closer to 100 it is, the better the chance of winning your stake back on any given spin – hypothetically, at least, as this is calculated over a large number of spins.

slotsia

Volatility

This refers to how often a slot pays out; highly volatile slots pay out infrequently but amounts tend to be larger, with low volatility doing the opposite. You should always look at this before playing but it is not enough on its own to decide on a game – Mega Moolah, for example, has low volatility.

So, in conclusion, there are multiple factors that determine whether you win on a jackpot slot. While you can have control over certain areas such as stake limits and paylines, the reality is that – particularly with progressives – it is often a matter of being in the right place at the right time.

Frequently Asked Questions

Jackpot slots are often complicated to understand, so we have compiled a list of popular questions and answers to help you get your head around them.

From a purely financial point of view, yes. There have been instances where players have won massive jackpots from small stakes. If you are happy playing titles that pay out amounts little and often, though, you may want to give jackpot slots a miss.

This varies from one jackpot slot to another, but you are nearly always going to have to land three or more of the highest value symbol in order to get the maximum win. This depends on the reel layout and game itself, so always familiarise yourself with the paytable before you start.

You will need a huge dose of luck in order to land the jackpot on a slot. Some titles require you to unlock a bonus game to be with any chance of getting a big win, but even those with more traditional mechanics need you to match symbols across the reels.

There have been multiple massive winners while playing online slots, with prizes well over a million pounds. These are decidedly rare and often come on network progressive games across multiple casinos but a player was recorded landing over €18m on Mega Moolah in 2018.
