    What are Progressive Jackpot Slots

    Progressive jackpot slots are a special type of online slot game characterised by its ever-increasing jackpot prize. Unlike online slot games with fixed jackpots, progressive jackpot slots feature a jackpot that keeps on growing with each bet placed by players.

    Amongst some of the most popular and well-known progressive jackpot slots, there is Mega Moolah by Microgaming, Arabian Nights and Hall of Gods by NetEnt and the Age of the Gods game series by Playtech.

    How Progressive Jackpots Work?

    Progressive jackpots keep on growing with each wager placed by players until the jackpot drops and is won. When players place bets on a progressive jackpot slot, a small percentage of each wager contributes to the jackpot pool.

    The jackpot can be triggered in several ways, depending on the jackpot slot. Some progressive jackpot slots have a random jackpot feature, where the jackpot can be snapped up on any spin, while others may require a number of specific symbols or a bonus round to activate it.

    How Are Progressive Jackpots Calculated in Slots?

    Progressive jackpot games are calculated on many factors, including the starting seed amount, the contribution rate and the game’s rules as follows:

    💰 Contribution rate: This refers to the small percentage of each bet placed by players. The common contribution rates range from 1% to 5% of each bet.

    🌱 Starting seed amount: The starting seed amount refers to the initial jackpot value funded by the online casino. When the jackpot is won, it resets to this seed amount before beginning to accumulate again.

    📈 Accumulation progress: The accumulation process keeps on going until the jackpot is won.

    Understanding Jackpot Triggering Mechanisms

    Knowing and understanding the various jackpot triggering mechanisms is important not only to boost your chances of winning the jackpot but also for generating regular wins. Here are 5 of the most prominent mechanisms:

    1. Random jackpot: Some progressive jackpot slots come with a prize that is triggered at random. Essentially, the jackpot can be won on any spin.
    2. Bonus round: Many jackpot slots require players to enter a bonus round for the chance to win the jackpot. The bonus round is generally triggered by landing a number of bonus symbols on a single spin.
    3. Symbol Combo: In some games, the jackpot can only be won by landing a specific combination of symbols on the reels.
    4. Progressive jackpot wheel: In some games, there is a special wheel that must be spun to win a jackpot.
    5. Jackpot drop: A jackpot drop mechanism refers to a jackpot that can be won randomly at any time during gameplay.

    Tips for Playing Progressive Jackpot Slots

    Online slot games are games of chance, and while they are luck-based there are some methods you can apply to maximise your chances of winning:

    • Bet Max Coins: Many players swear that you should bet the maximum number of coins in a bid to win the jackpot. While we don’t condone this, opting for the full number of paylines when playing a jackpot, gives you better chances.
    • Bankroll: Progressive jackpot slots can be highly volatile and generally come with a lower payout percentage. Manage your bankroll wisely to make your gaming session stretch out.
    • Casino bonuses: Take advantage of casino bonuses and promotions, but be mindful of wagering requirements.
    • Licensed casinos: Play at licensed and regulated casino sites for a fair gaming session. UKGC and the MGA are some of the most reputable gaming authorities.
    • Play for fun: Before you wager on real-money games, take the time to explore the games by playing in free demo mode. This way you can figure out if a game is to your liking.

    Difference between local and networked progressive jackpots

    Local and networked progressive jackpot slots are two different types of progressive systems. Local progressive jackpots are limited to a single casino, while networked progressive jackpots are linked to several casinos.

    The jackpot size of local jackpots is also significantly small since they are limited to the bets placed within the casino. Local progressive jackpots tend to grow comparatively slower as well.

    That said, the chances of winning a local progressive jackpot may be slightly higher since the player pool is smaller.

    How to Choose the Best Progressive Jackpot Slot Machine?

    When choosing the best progressive jackpot slot game to play, you should look for several factors, including the following:

    🕹️ Game developers: You should opt for reputable software game developers, who are known for their quality. Game developers, such as NetEnt, Microgaming and Playtech have a good track record.

    💸 Payout percentage: Look for slots with a high payout percentage. Games such as Mega Moolah are fun, but they come with a lower payout percentage, meaning that you won’t achieve that many wins.

    🏆 Jackpot size: Some players might prefer games with a large jackpot, while others may prefer smaller ones.

    ⚡ Volatility: Be mindful of the variance of the jackpot slot, so you can figure out how often a game will play

    ⚙️ Jackpot mechanism: Familiar yourself with the workings of a game and what is required to trigger a jackpot.

    Record-Breaking Progressive Jackpots

    Record-breaking progressive jackpot slots have captured the attention of online casino players all over the world.

    Mega Moolah holds the Guinness World Record for the largest online slot jackpot ever won. In October 2015, a British soldier named Jon Heywood won an astonishing £17,879,645 playing Mega Moolah at Betway.

    Mega Fortune is another progressive jackpot slot known for its massive payouts. In January 2013, a Finnish player won £17.8 million playing Mega Fortune at Paf Casino, setting a new world record for the largest online slot jackpot at the time.

    In April 2015, a Norwegian player struck gold by winning £7.8 million playing Hall of Gods at Betsson Casino.


    Progressive Jackpot Slots offer players the excitement of spinning the reels and the chance of winning life-changing sums. Players are drawn to these games for their entertainment value, the appeal of their progressive jackpots, and the chance to become part of online casino history with just a single spin.

    You should always keep in mind that online slot games, and more explicitly progressive jackpot slots are games of luck. As mentioned earlier, knowing the game rules and the triggering mechanisms can help you figure out if a game is to your liking.

    Even more so, playing high RTP progressive jackpot slots with an optimal variance level could bode well. Bear in mind, that highly volatile online slot games pay out substantially albeit infrequently.

    Don’t set off playing progressive jackpot slots with the aim of winning a jackpot. Have fun and manage your bankroll properly. Taking advantage of casino bonuses and promotions can help extend your gaming session.
