Find out more about this type of online slot game below.

    What Are Progressive Slots?

    If you enjoy spinning the reels of slot games, you will no doubt have heard of progressive jackpot slot games. What sets this type of slot game apart from other slots is the type of jackpot up for grabs. Rather than having a fixed jackpot, the progressive jackpot will continue to grow until one lucky player wins the entire jackpot amount.

    Progressive jackpots are available both online and at land-based casinos. As the jackpots available can grow massively, there is a chance to win millions. This is something that is just not available with most other types of regular slots.

    How Do Progressive Slots Work?

    Progressive jackpots work by lots of players all contributing to the prize pool. Each time a bet is placed on that slot game, or other slots that it is networked with, a portion of that bet will be added to the progressive jackpot. For this reason, you may find demo slot games with this type of jackpot available to enjoy but you will not find free progressive slots where you will still be eligible for the jackpot prize.

    Different game providers will contribute different percentages to the jackpot pool. For example, with a software developer such as Red Tiger Gaming, around 3% of bets will be added to the jackpot fund when playing progressive slots. There is always a minimum amount of money that can be won with progressive jackpots and this is known as the ‘seed’.

    How to Win a Progressive Jackpot

    You can then spin the reels and enjoy the exciting bonus features that all the games have to offer. The way to win a progressive jackpot will vary depending on the slot game you are spinning. Some of the ways that you can get a progressive jackpot win include:

    •  Landing three or more special jackpot symbols on a single spin
    • Get a jackpot win via a bonus feature
    • Spin a bonus wheel or play a mini-game to be awarded one of multiple jackpots such as a mini, mega, major or grand jackpot
    • If it is a timed jackpot, the jackpot will be more likely to drop closer to the deadline

    Slot games that offer progressive jackpots are like all other slot games in that they use a random number generator. You are never guaranteed to win big jackpots when playing any type of online gambling game.

    Once the jackpot has been won, the progressive jackpot resets to its minimum level.

    How to Play Progressive Slots Games

    Spinning the reels of progressive jackpot games is easy and you can get started right here at JeffBet online casino in just a few minutes:

    1.   Sign in to your JeffBet account or make an account if you have not done so already
    2.   Visit the casino games lobby
    3.   Click on the ‘Jackpot’ section
    4.   Choose your favourite progressive slot machine
    5.   Set your bet per spin and paylines if required. In some progressive slot games, you must bet the max amount or there will be a minimum bet that must be placed to be in with a chance of winning the jackpot prize
    6. Start spinning the reels to potentially win big jackpots!

    If you are used to playing non jackpot slots, you will have no trouble playing a progressive slot machine game as they work in the same way. 

    The Different Types of Progressive Slots

    When playing at online casinos, you will find many different types of progressive slot machines. Each of the progressive casino games offers something a little bit different. This is why it is important to know the difference before you play progressive slots as it can potentially impact your gameplay.

    The three main types of progressive slots online are:

    Progressive Jackpot SlotWhat It Offers
    Standalone progressiveA standalone progressive jackpot slot will only pay out a progressive win from the wagers placed on that particular slot game. It is usually reserved for physical casinos such as those found in Las Vegas alongside some online casinos.
    Wide area network progressiveThis is one of the most popular types of progressive games available to play. Each time someone bets on this jackpot slot, they will contribute to the progressive jackpot win up for grabs. This means that multiple machines can all contribute to the prize pool. The same jackpot will be available at every casino. It does not matter if two players spin the game at the same casino or different casinos, as the progressive jackpot pays out the same prize. However, your odds of winning are low compared to other types of online slots and the progressive jackpot does not pay out frequently.
    Local progressive jackpotLocal jackpot online slot games are a little more exclusive than the wide area network games. The jackpot in these games is usually reserved for one online casino or multiple casinos with the same owners. This means you have better odds of winning as the player pool is smaller. However, the jackpot will not be as large.

    Advantages of Playing Progressive Slots

    There are many reasons why players opt to spin progressive jackpot slot games. Here are some of the advantages of playing a progressive slot machine:

    • Grand prize – of course, the top reason why players opt to spin progressive games is the large sums of money up for grabs. The jackpots in these games are normally always bigger than regular slots and there is a chance you could win a life-changing sum of money
    • Themes and graphics – progressive jackpot slots have the highest quality graphics and with so many to choose from, there is a theme that will appeal to every player
    • Bonus features – while some progressive jackpot slots are very simple, many offer a wide range of bonus features including wilds, free spins, multipliers, picking games, mini-games and more
    • Ease of use – progressive games play in the same way that regular slots do. You can set up your bet and get started spinning the reels in seconds

    Disadvantages

    Alongside all these advantages of progressive slot games, there are a few disadvantages too including:

    • Betting ranges – most progressive jackpot slots have a wide betting range to suit most players, however, to be eligible for the big jackpots, you may need to bet higher amounts
    • Lower RTP – progressive slot games normally have a lower RTP than regular slot games due to a percentage of the bet contributing to the jackpot pool

    As you can see, there are many more advantages when spinning the reels of progressive jackpot slot games. These are the perfect slots to spin for those who want to play a high-quality game that can potentially award a huge payout.
