We’ll even show you which great casinos offer big prizes, especially on daily jackpot titles.

Mega Moolah progressive slot

Regular online slots usually carry a fixed jackpot which you can win through hitting 5-of-a-kind or a bonus feature. Progressive slots are different – they carry a jackpot which keeps climbing until one player takes it down.

Progressive real money slots are normally linked across multiple online casinos. Every time you play, a tiny fraction of your stake is added to the jackpot pool. The remainder goes towards playing the slot itself. The more casinos that share a game, the bigger the jackpot gets. Plus, some progressive jackpot slots share the same prizepool.

  • Standalone Progressive Slots: A standalone progressive is a single slot that offers an exclusive jackpot. You’ll have to play that slot at a particular casino for a chance of winning the big one.
  • Progressive Slots Series: Some developers offer a series of progressive slots that all share a single jackpot. In games like Playtech’s Age of the Gods series, you can win one of four separate jackpots depending on how the bonus game pans out.
  • Age of the Gods Mystery Jackpot (Playtech)
    Games include: Age of the Gods, Age of the Gods Medusa & Monsters, Age of the Gods Epic Troy
  • PowerPlay Jackpot (Playtech)
    Slots include: Book of Kings PowerPlay Jackpot, Blazing Bells PowerPlay Jackpot, Storms of Ice PowerPlay Jackpot
  • DC Super Heroes (Playtech)
    Games include: Justice League, Batman and Catwoman Cash, Superman

How to Win Progressive Games

Progressive slots award jackpots in different ways. Typically, you’ll have to trigger a bonus feature first in order to take down one of the game’s jackpots. A tiny percentage of each spin goes towards building the jackpot. This is normally around 0.99-1% of the total stake. To start playing slots, sign p for an account first:

  • Go to William Hill Casino site to register
  • Use promo code to claim sign-up bonus
  • Deposit, go to jackpot slots section to start playing

The bonus feature is usually triggered at random during any base game spin. Alternatively, you may have to land scatter symbols in certain positions. As long as you are playing for real money, you’ll be able to activate the jackpot game. However, some games require you to bet at the maximum stake in order to qualify.

The bonus feature differs from game to game. It might involve a pick’em style game where you have to match symbols on the screen. Simply reveal matching symbols to win the corresponding progressive jackpot. Games like Microgaming’s record-breaking Mega Moolah use a wheel bonus where you have to line up arrows to win one of the game’s jackpots.

Slots with jackpots are hugely popular at UK online casinos. In fact, British gamblers have been winning 5 and 6-figure jackpots for the past few years. Here are some of the largest online progressive jackpots ever taken down.


As a slots player, you can claim some great casino bonuses. A gambling bonus gives you an opportunity to earn free spins on big-name slots or claim free cash from the casino. All you need to do is complete your registration form and make a first deposit. You’ll be awarded free spins to use on selected slots. However, some casino apps also award no-deposit bonuses where you can play progressive slots with zero risk. As long as you meet the wagering requirements, you’ll have a chance to unlock free money.

Due to their volatile nature and massive jackpots, not all progressives will be eligible for a casino bonus. Always check the casino’s terms and conditions page first to see which online slots are exempt from the bonus.
