Progressive slots offer the chance to win some of the biggest casino payouts, often from a single spin. They’re built around a jackpot that grows with every bet placed across the linked network, and it keeps rising until someone hits the top prize. In popular wide-area progressive jackpot slots like Mega Moolah, the payout can easily pass £10 million.

Mega Moolah is the gold standard and the “king” of other progressive slots online, and with good reason. The African Safari-themed progressive slot has churned out some of the biggest jackpot wins, including a record £13.2 million payout in the UK at Betway and €19,430,723 (about £16.9m) overall.
It sports four jackpot tiers, with the Mega pot typically dropping every 8-10 weeks. With £1,000,000+ seed, you can bet from 25p to £5, with a better shot at the Free Spins feature than the progressive jackpot. In the bonus round that gives 15 free spins, the Lion Wild 2x your payout and all wins are tripled.

What are progressive slots?
A progressive jackpot slot is a casino game in which a portion of every bet is added to a shared jackpot pool. These games can link across many casinos, sometimes hundreds worldwide. Because of this, the jackpot can reach millions before it resets to its seed amount when someone wins it. Mega Moolah and Mega Fortune, for example, both reset to £1 million. Unlike classic slots with fixed payouts, the full jackpot goes to the player who triggers it.
In the UK, all progressive slots are licensed by the UKGC and must use RNG systems certified as fair by independent testing labs such as eCOGRA, iTech Labs, and GLI.
How do progressive jackpot slots work?
When you place a bet on progressive slots online, a small part of your stake goes into the jackpot pool. This amount is usually between 1% and 5% of each spin. The rest of your bet covers the base game payouts and the house edge. These small contributions add up quickly because thousands of players use the same network of casinos.
Progressive slots RTP and volatility explained
Progressive slot games tend to sit at the higher end of volatility because a large share of their overall returns is tied to the jackpot. This means wins can be less frequent, but the payouts, especially the jackpot tiers, can be huge, often reaching £100k or more.
The base progressive slots RTP ranges from 88% to 90%, and they rarely crack past 92%. That’s because a portion of the RTP is allocated to building the jackpot. When the jackpot grows, the overall RTP can rise significantly, sometimes pushing past 95%, as seen with Mega Fortune at 96.5%.
Types of progressive jackpot slots
Players will find many types of progressive jackpots, from stand-alone jackpots that grow only on that machine to wide-area jackpots linked across thousands of sites.
Standalone progressive jackpot slots
Here, the jackpot grows solely from wagers placed on that specific game, and the top prize increases more gradually than in network versions. The most popular standalone progressive titles include Mega Moolah Isis, and Book of Ra Deluxe.
Local progressive jackpot slots
Also called in-house progressives, these link multiple games within a single casino or operator. Because several titles feed into the same pool, the jackpot builds faster than in standalone slots. Think Divine Fortune and the Age of the Gods series.
Wide-area progressive jackpot slots
Wide-area networks wire the same progressive jackpot game across dozens or hundreds of casinos in different countries. For example, every player who spins Mega Moolah at any linked site contributes a little to the shared top prize, and they can land the £10+ million. Other wide-area progressives include Mega Fortune, WowPot, and King Millions.
Must-drop jackpots
Must‑drop jackpots have a guaranteed payout window. Daily drops must pay within 24 hours, while hourly drops must land within 60 minutes. In most Jackpot King network slots, the countdown triggers a must-drop prize.
Progressive slot games vs classic fixed-jackpot slots: How are they different?
Fixed-jackpot slots offer a maximum win that’s x your stake, such as 1,000x or 5,000x. This amount never changes, no matter how many players spin or how long it’s been since the last win.
Progressive slots, on the other hand, have a jackpot that grows with every bet placed. Here’s a side‑by‑side comparison:
| Feature | Progressive Slot Games | Regular Slots |
|---|---|---|
| Jackpot Size | Massive and increases with each bet | Smaller and fixed |
| RTP | Lower (88% to 92%) | Higher (95% to 98%) |
| Volatility | Mostly high | Mostly low to medium |
| Win Frequency | Lower to rare hit rates | Higher hit rates |
| Bet Requirements | Must play max bet in most | Flexible bet size |
| Jackpot Trigger | Often triggered randomly | Mostly triggered by landing scatter symbols |
How to win on progressive jackpot slots
As with any slot, winning on progressive jackpots is mostly down to luck, but these tips can help you play smarter and get more out of the experience.
1. Study how the jackpot is triggered
Each progressive slot has its own way of activating the jackpot feature. Check the paytable before you start so you know exactly what triggers the bonus round.
2. Manage your bankroll properly
Set a clear budget and break it into session limits. Progressive slots are high‑variance, so poor bankroll management can drain your balance quickly.
3. Check the minimum bet needed for jackpot eligibility
Many progressive slot games require a minimum bet (or even a max bet) to qualify for the top jackpot. Always check the game’s rules first.
4. Know the RTP and volatility of the game
Higher RTP (around 96% or above) generally gives better long‑term value, and volatility tells you how often you can expect wins.
