Progressive Jackpot Slots

Progressive jackpot slots are different to normal slot games because they offer prizes that are progressive rather than fixed. This means that the jackpot increases in size every time a player makes a bet. Unlike regular slots, many progressive jackpots regularly rise to be worth millions of dollars a time.

When a jackpot slot is won, the prize is paid out and returns to its standard, default level. Then it will build up again over time as more players wager on the game. 

Some progressive slots are pooled over a network of casinos, which means that several casinos can offer the same jackpot slot and every wager placed on the slot at each casino contributes to the jackpot. In these instances, someone not playing at your chosen casino could win the top prize on the game you are also playing.

This payout exceeded the previous record, which was also set by Mega Moolah. The slot paid out That figure was €17,879,645 EUR ($30,265,645 NZD) in 2015 to a player called Jon Heywood, from Cardiff, Wales, who was playing on the Betway website. He won with just a 25 pence bet. The payout earned Microgaming a Guinness World Record title for ‘Largest jackpot payout in an online slot machine game’.

How progressive jackpots work

Progressive jackpot slots offer some of the biggest payouts across the entire online casino landscape as their value increases until one lucky player wins the top prize. These are different to fixed jackpots, which pay out a set amount when a player lands the required combination.

Progressive slots can either by local, which means the only players playing at that casino contribute to the jackpot, or they can be pooled, also known as linked jackpots, which means players across a network of different casinos contribute to the jackpot.

Progressive jackpots begin as a set minimum amount, and then each time the reels of a jackpot slot are spun, a percentage of the wager used to play the game is added to the prize. Once the prize is won, it returns to the base value and begins building up again as players stake their bets.

Aside from the progressive element, jackpot slots are pretty much the same as standard slot games. It’s always a good idea to familiarise yourself with a specific game’s rules before starting play, looking at return to player (RTP) percentages and the paytable.


What is RTP?

Return to player (RTP) is the expected payback percentage of online slot games, based on how much the slot pays out on average. For example, if a progressive slots game has an RTP of 96%, on average you could expect to win back £96 for every £100, though bear in mind you can easily win more or less than this amount ay any one time.

How do I know progressive slots are fair?

All online slots at licensed casinos use random number generator technology to determine which symbols land on the reels every time you spin. This ensures the game is completely random and not rigged. Progressive slots at licensed casinos are also tested by independent testing agencies to ensure fairness.
