Progressive Slots

Online slots are fun, exciting, and easy to play. They also present an opportunity to become a millionaire overnight, thanks to the exceptional payouts available in progressive jackpot slots.

So what exactly is a progressive jackpot?

All slot games offer a jackpot, which is the highest cash prize a player could win on any spin. Most slot games have a fixed jackpot; a calculated, fixed amount that is a multiplier of the player's bet. For example, 1000x jackpot will pay 1000x the player's wager.

A progressive jackpot, on the other hand, is a jackpot that increases in value each time a game is played (and the jackpot is not won). A small percentage of every wager is allocated towards the jackpot on every spin, therefore the jackpot 'progresses' and increases in value as long as players are betting and spinning the reels. The pot keeps rising in value until one lucky player wins it all!

There are generally three types of Progressive Jackpots available in both land-based and online casinos.

  • Standalone Progressive Slots are not linked to any other machines or networks and are usually found in land-based casinos. Only the bets placed on that particular machine will contribute towards the jackpot, which typically pays less than 10 000 coins.
  • A Local Progressive Jackpot is made up of a network of slot machines within the same casino. These slots offer higher value jackpots because more players are contributing towards the single pot, however, the chances of winning are slightly lower. The contributions to the jackpots can be made up of different slot titles across the casino, as they are all connected to the same progressive jackpot.
  • Networked Progressive Slots (also known as Wide Area Network Progressive Jackpots) are progressive slots that are linked across multiple casinos with one shared progressive jackpot. These are commonly found online and usually offer massive jackpots in the millions, because the same game is being played across hundreds of casinos, with a vast player-base contributing towards one potentially life-changing jackpot.


Bigger jackpots attract more players, which explains why Networked Progressive Slots are by far the most popular games online. In 2018 Microgaming's Mega Moolah paid out a record €18,915,872.81 jackpot, setting a new payout record for the popular online slot. This win exceeded the €17,879,645.12 payout that set the world record in 2015, which earned Microgaming a Guinness World Records title for the 'Largest jackpot payout in an online slot machine game.' In Jan 2013, one lucky player hit the EUR 17,861,800 jackpot playing NetEnts Mega Fortune online slot.


Progressive Jackpots can be won in a variety of ways, and it all depends on the game mechanics and rules of the slot itself. Some jackpots are won by landing the correct symbols in a particular combination across the reels. Other jackpots can only be won when the player triggers a Bonus Game. They may, for example, involved a jackpot wheel. Some progressive slots feature multiple 'tiered' jackpots with 3 or 4 ascending progressives in one game.

The Progressive Jackpot value is usually clearly and boldly displayed within the game, typically in the form of a progressive meter or 'ticker' that resembles the traditional LCD panels seen in land-based casinos.

When a player wins or ‘hits’ a jackpot, the value is reset to a pre-determined starting value (known as the seeding value). Progressive slot play action tends to 'cool down' when reset (in terms of the number of players) because players tend to wait until the jackpot starts to gain momentum and reach higher values. This is when players and casino marketers begin to buzz with the hype of potentially substantial progressive payouts.

Progressive Slots FAQ

Do online progressive jackpots really exist, and can they actually be won?

Absolutely! There is some speculation that progressive jackpots are a marketing ploy to attract players to casinos. This is completely false. There are many gambling websites and forums dedicated to progressive jackpot success stories. Some player's life-changing wins have been featured in news articles across the globe.

Is it safe to play Progressive Slots?

Yes. Online gaming is heavily regulated, and online casinos have to be licensed and compliant with the laws and regulations established by gaming authorities like eCOGRA, Canada's Kahnawake Gaming Commission (KGC), Malta Gaming Authority (MGA) and UK Gambling Commission (UKGC). Always play at an established, licensed, and reputable casino that partners with established providers like NetEnt, Play'n Go, Microgaming, Playtech, IGT, BluePrint Gaming, BTG, etc.

Can Progressive Jackpots be rigged or triggered by the casino?

No. The casino has no influence or control over the outcome of progressive slot games. All reel-spin results are determined by a sophisticated mathematical algorithm called a Random Number Generator (RNG). The RNG generates thousands of unique number sequences every second and ensures that the outcome of each spin of the reels is random and can not be 'fixed.' The RNG is owned and run by independent licensed and certified game providers and not the casino. Previous wins or losses will have no bearing on the next spin, and there is no way of predicting when a jackpot will hit.

Do I have to place a higher bet to qualify for a progressive Jackpot?

Yes and no. This depends on the game and the provider. Some games require players to place a premium bet (or play max bet) to stand a chance of hitting the top paying jackpot. We recommend reading the paytable rules of the slot you are playing to understand how the wagering works.
