Many people would love to have their lives transformed by hitting a huge jackpot with a lucky spin of an online slot. Progressive jackpot slots offer you the chance to do just this, with potential prizes that are simply out of reach with even the highest paying regular slots.\u00a0<\/span><\/p>\n

Progressive slots take a portion of every stake made by players and add them to one or more jackpot prize pools. These build up as people play on the slot, until the jackpot is triggered.<\/span><\/p>\n

In this article, you\u2019ll see how progressive jackpot slots work, see some of the biggest jackpot wins, and find out how you can use progressive slots to your advantage by doing <\/span>casino offers<\/span><\/a>.\u00a0<\/span><\/p>\n

How Progressive Slots Work<\/span><\/h2>\n

Jackpot Accumulation<\/span><\/h2>\n

Progressive jackpot slots work a little differently to regular slots, by taking a portion of your stake and adding this to a jackpot fund. The screenshot below shows Mega Moolah, which is an example of a progressive jackpot slot:<\/span><\/p>\n

Not taking into account the jackpots, Mega Moolah has a very low <\/span>Return To Player<\/span><\/a> (RTP) of 88.12%. On top of this, there’s an additional jackpot contribution of 5.30% of your stake, meaning that for every \u00a3100 staked, \u00a35.30 is added to the jackpot fund.<\/span><\/p>\n

This fund is shared between the four jackpots – Mini (red), Minor (orange), Major (yellow), and Mega (white). In the screenshot, the value of the Mega Jackpot at the top left is \u00a33,620,256.83 at the time. Funded by the 5.3% jackpot contributions, this jackpot builds up until a lucky player eventually wins it.<\/span><\/p>\n

Networked and Standalone Progressive Jackpot Slots<\/span><\/h2>\n

There are two main types of progressive jackpot slot: standalone and networked. A standalone progressive slot accumulates the jackpot fund from just one machine or a single slot on an online site.\u00a0<\/span><\/p>\n

Networked progressive jackpot slots work a little differently. These link multiple machines or slots, sometimes across different casinos or casino sites, all of which share the same jackpots.\u00a0<\/span><\/p>\n

Because there\u2019s far more money being put into networked progressive slots, the jackpots grow much faster. You\u2019ll tend to find that online progressive jackpot slots are networked slots.\u00a0<\/span><\/p>\n

Jackpot Seed Money<\/span><\/h2>\n

When a player of any of these slots across all of the casinos that host them wins one of the jackpots, the jackpot amount drops to a minimum amount. The Mega Moolah Mega jackpot resets to \u00a31,000,000 after being won, for example.<\/span><\/p>\n

This minimum amount is known as the <\/span>seed<\/b> amount, and it’s guaranteed and provided by the casino or slot provider. After being re-seeded at this minimum amount, the jackpot starts to grow again, funded by players’ jackpot contributions as before.<\/span><\/p>\n

Random Number Generators (RNGs)<\/span><\/h2>\n

Like all online slots, progressive jackpot slots use Random Number Generators (RNGs) to generate their results and ensure fairness. Since each spin is independent from all other spins, RNGs make it impossible to predict when a jackpot will hit.<\/span><\/p>\n

How Are Jackpot Wins Triggered?<\/span><\/h2>\n

Online progressive jackpot payouts can be triggered in several ways:<\/span><\/p>\n
