?? How Progressive Jackpot Slots Work

Slot games are the cornerstone of every online casino, and progressive jackpot games are some of the most popular slots with British players.

Progressive jackpot games are played exactly like regular real-money online slots – you spin the reels and earn bonus spins or a bonus round. You win the jackpot if you hit a certain winning combination or finish the bonus rounds.

The progressive prize pool for a jackpot slot increases every time someone plays any of the games that are part of this jackpot, and then resets to a base minimum once it has been won. Most progressive games will have a series of different sized jackpot, and the size of your win will depend on which jackpot you hit.

There used to be a relatively limited number of online slot games with an online progressive jackpot, but in 2024 you can spin the reels and play for mighty jackpot prizes at most of the best UK casino sites.

?? Best Jackpot Slot Games: Top 10 in 2024

There are hundreds of slot games that have a progressive jackpot you can win at British casino sites. These games are played the same as regular online slot games, with the main difference being the size of the potential payout.

These are the best jackpot slots you can play in the UK:

  1. Mega Moolah by Microgaming
  2. Age of the Gods by PlayTech
  3. Mega Fortune by NetEnt
  4. Divine Fortune by NetEnt
  5. Hall of Gods by NetEnt
  6. Joker Millions by Yggdrasil
  7. Leprechaun’s Luck by Playtech
  8. Book of Atem by Microgaming
  9. Arabian Nights by NetEnt
  10. African Legends by Microgaming
Top progressive jackpot slots UK

The biggest progressive slots can have jackpot prizes worth several million pounds!

1. Mega Moolah – 88.12% RTP

The Guiness World record for the biggest jackpot slot online payout of all time is held by a British man who won £13,209,300 on the Mega Moolah jackpot on 6 October 2015. This is one reason that this title is the most popular jackpot game in the UK today, and the best progressive slot of all time.

The original slot game has an African Savannah theme, and a 5×3 grid leading to 25 paylines in the base game. A cut of every spin goes into the progressive jackpot, and the kitty can grow to a nice six figure sum! Although the base return to player is under 90%, each bet will put you in with a chance to bag one of four jackpots: the mini, minor, major or MEGA!

If you want to play Mega Moolah and be in with a chance of becoming a millionaire then head to Zodiac Casino where just £1 will get you 80 free spins!

BonusFinder Tip

You can get 80 chances to win the Mega Moolah jackpot for just £1 at Zodiac Casino

2. Age of the Gods – 95.02% RTP

There are dozens of different Age of God slots in PlayTech’s progressive network. Land all five jackpot symbols on one payline to win 200x your bet, or trigger the bonus mini-game to be in with a chance for the jackpot prizes. These come in four tiers: Power jackpot, Extra Power, Super Power, or Ultimate Power! This is one of the best jackpot slots around, with surprisingly wide range of themes in the pantheon.

The welcome bonus at BetFred Casino will get you up to 200 wager-free spins to enjoy on selected Age of the Gods games, when you deposit and playthrough just £10.

3. Mega Fortune – 96.6% RTP

NetEnt’s Mega Fortune has long been after Mega Moolah’s crown for most popular jackpot slot game. It also has 5 reels and 25 paylines, with an up-market luxury theme, giving you a taste of the finer things the jackpot could unlock!

4. Divine Fortune – 96.59% RTP

Divine Fortune is another winner from NetEnt, with 20 paylines, and medium volatility. Divine Fortune has Ancient Greek imagery and lots of bonus features including respins, multiplying wilds, free spins, and a bonus game where you can potentially win one of two fixed jackpots or the progressive Mega Jackpot. The progressive jackpot for the Divine Fortune slot regularly reaches six figures.

5. Hall of Gods – 95.30% RTP

Hall of Gods is NetEnt’s Viking themed Jackpot slot game where you can sail the seas to find a progressive jackpot that starts from £500,000. This jackpot has not paid out as often as the more famous Mega Fortune, but the average £5.3 million drop is considerably higher.

6. Joker Millions – 94.30% RTP

Joker Millions, by Yggdrasil, has 25 paylines that pay from left to right. Each joker you encounter has a Mystery Win of up to 1000 coins, and collect all 15 jokers in a jackpot spin to win the jackpot! Joker Millions is a perfect blend of classic slots play with exciting progressive jackpots!

7. Leprechaun’s Luck – 95.38% RTP

This charming slots game is our favourite Irish themed jackpot, with simple gameplay and bright graphics. There are 5 reels, and 20 paylines, and you need to find three correct symbols to unlock a bonus round of up to 20 free spins. Will you have the luck to find the pot of gold at the end of the rainbow?

8. Book of Atem – 96.45% RTP

This Microgaming progressive jackpot slot transports you to ancient Egypt and the original grandeur of the pyramids. Find the Book of Atem Wild Scatter jackpot symbols and get the chance to spin the WowPot jackpot wheel and collect one of four progressive cash prizes.

9. Arabian Nights Jackpot – 95.60% RTP

This online slot is one of NetEnt’s oldest and most popular jackpot games of all-time, and it comes with both the mighty NetEnt Jackpot, which is contributed to by players from all over the world, AND as a local progressive jackpot for the casino you choose to play at.

10. African Legends Jackpot – 94.92% RTP

Microgaming’s African Legends jackpot slot is a 5 reel safari-themed game, with 243 ways to win. The Rolling Reels feature triggers every time you land on a winning combination, and if you get 4 or more Rolling Reels in a row you can win free spins with multipliers of between 5x and 10x. Trigger 8 Rolling Reels and you might hit the progressive jackpot!

mega moolah best slot jackpot

Mega Moolah is the best progressive jackpot slot in 2024 according to our casino experts.

?? New Jackpot Slot Game

The most exciting new progressive jackpot slot game is Mega Moolah Megaways by Gameburger Studios. This game hit UK casinos on 18 December 2023 and combines two of my favourite types of slot game: the legendary Mega Moolah jackpot experience and the thrill of the Megaways features. This game promises plenty of free spins, infinite escalating multipliers, rapid retriggers, and an extra horizontal reel, combined with the classic progressive jackpot wheel from Mega Moolah with the top prizes reading into the millions.

?? Types of Jackpot Slots

There are different types of progressive slots: standalone, wide area, and local area jackpots. Most casinos offer a combo of these, and you can choose an annual payment or a cash payout if you win the top jackpot.

  • Standalone Progressives
    These are not attached to other slot games, meaning the jackpot only increases as players play on this specific slot machine. The winnings tend not to be as high on local progressives, as there are fewer players playing. On the other hand, your chances to win might be better than on a wide area network jackpot game.
  • Local Area Progressives
    These types of jackpot slots are connected to others in the same area through a central server, often within the same online casino. The games have a shared progressive jackpot, which progresses as players play on any of the connected games.
  • Wide Area Network Jackpots
    These are the largest progressive jackpots you can find as the same prize pool is contributed to from many different casino sites. The Progressive Play Network Jackpot Slots are a good example of this kind of wide area system.
  • Must Fall or Daily Drop Jackpots
    You will also find time-limited jackpot slots at some casinos. Red Tiger first introduced the concept back in 2016 when Paddy Power wanted something special for slot players during the Euro Cup. The original Must Drop was a slots jackpot that had to be to be won by the end of the game, and the chance of winning increased the closer the time got to the full 90 minutes. Nowadays you can find a range of daily jackpots or hourly must-drop slots from different game providers at most online casinos.
BonusFinder Expert Pick

BetMGM Casino has their own local area Supersized jackpots that you can win when playing some of the most popular games on their site like Starburst or live roulette.

? Tips on How to Play Jackpot Slot Games

While there is no optimal strategy for playing online slot games, you can follow some general tips to improve your (very small) odds of winning the jackpot. Remember that jackpot slots work on random number generators, and even consistent gameplay won’t guarantee you hit the jackpot. Often you have to place a maximum bet and make it through a bonus feature.

  • Play When the Jackpot is Big:
    What’s the point of winning a few hundred dollars when you can win a few hundred thousand? Your chances of winning a progressive jackpot are slim at best, so why not go for it when the pot is actually significant. Also, some claim you’ll eventually reach the break-even point, and then each wager becomes a positive expectation bet.
  • Stick to Standalone Progressives:
    Your chance to win is marginally better with a standalone progressive slot. You probably won’t win a million dollars on these jackpot slots, but maybe enough for a new car.
  • Consider Which Game to Play First:
    You might only be eligible to win the jackpot if you place the max bet on some games, but other machines have a minimum amount one player has to play with. Second, the jackpot hits more often on some progressive slots. This might be related to the fact that more people play certain jackpot slots, but it never hurts to do some investigative work on multiple slot games.

Odds to Win

Unfortunately, you can’t calculate the odds of winning a progressive slot game, as online slots are coded to work randomly. There’s no way of knowing when a progressive jackpot will be more likely to drop, although you might be able to find the average time between jackpot wins for any game.

In addition, all games carry a return-to-player (RTP) percentage that’s less than 100%; this might also be referred to as the payback percentage. This means that in the long run, the casino will end up with profit due to the house edge; when someone wins the progressive jackpot, the losses have to be recouped from other players.

?Reasons to Play Jackpot Slots

You will find a great selection of the best jackpot slots at most UK casinos now, but are they worth playing? Many British players love the thrill of the progressive prizes and the small chance to bag a life changing win. However, they have higher volatility than other slots and you might lose more in the long run.

These are the main pros & cons of Jackpot Slots:

They are fun to play

You can pick and choose the jackpot slots that have highest real money prizes easily

The excitement of possibly winning the top prize can be exhilarating

There are lots of different themes so you'll find something to your taste

The chance to win the highest jackpots is minimal

You can run out of money fast if you are not lucky and get into the jackpot bonus rounds

Lower Return to Player (RTP) than other slot games

Some casino bonuses don't let you play jackpot slots

Not all, but most of them do. Some jackpots are fixed to a certain amount, and some of them are progressive jackpot pools.
