How Do Progressive Jackpots Work?

The system progressive jackpots use is a pot that inflates each time a player places a wager. Continual bets on the game drive the pool to increase to incredibly high amounts, sometimes even millions. Once a player claims the pot, it resets to its base amount and steadily climbs again. The process keeps repeating itself. The longer the pool remains unclaimed, the higher it rises. Most progressive slot games run across mobile platforms, including iOS, Windows, and Android. The mobile jackpot experience is as good as on a PC. The thrills and excitement are all there, and the potential to win can rival national lottery payouts. Progressive jackpot games filter a minor percentage of each bet which goes into the pot. Those types of slots serve up the best chance of winning an incredible payout.

Top Progressive Jackpot Slots UK 

The best jackpot slots in the UK tend to be in favour of those from Microgaming, Netent, Playtech, IGT, BTG and BluePrint. Below we've listed the top progressive slots boasting the biggest jackpots below. You will be able to find them at the most recommended casino sites here in the UK.

Mega Moolah

Mega Moolah jackpot slot has turned several players into millionaires. In addition, it holds the record of paying out the highest jackpot prize to date. Mega Moolah has a lively, festive safari theme and a straightforward layout, with five reels, 25 paylines, and vibrant animal symbols. They include monkeys, giraffes, elephants, and lions. A random jackpot appears during the bonus round; therefore, you can spin the wheel of fortune with four jackpots, the mini, minor, major or the mega. Mega Moolah is a classic progressive slot game that holds the world record for a jackpot payout of over £12 million! The game is top-rated, which is the primary reason the pot regularly inflates to such high amounts. 

Mega Fortune Dreams

Mega Fortune Dreams is a NetEnt release and sequel to the original Mega Fortune. The game has a 5-reel, 20 payline layout, with wild wins, free spins and no less than three progressive jackpots! The linking jackpot grows as players bet every single day. A minor percentage of each real money bet goes into the Mega Jackpot, and there will only be one winner walking away with that wealth. 

Major Millions 

Major Millions is a rather complex slot, which features both a 3-reel and 5-reel version, although the game most commonly played is the 5-reel version. Both games are linked to produce a combined jackpot. Major Millions has a military theme and features wilds and scatters that help trigger winning combinations but don't access any bonus games. The progressive jackpot is frequently around several hundred thousand pounds, although it recently superseded £1m. You win the big progressive by landing the five Major Millions symbols across the fifteenth payline. If you manage that, you'll win the top payout prize. Spins of this sort cost £3 per spin.

Divine Fortune 

Compared to Mega Moolah, Divine Fortune is more well-rounded; however, it's a progressive slot game that you can win hundreds of thousands playing. One of NetEnt's leading products, the game has a decent RTP rate of almost 97%. That comes with some drawbacks, however. You hardly ever see Divine Fortune's jackpot tracker reach the insane multi-millions of Mega Moolah slots. It rarely goes over a few hundred thousand pounds till someone claims the Mega Jackpot. Still, that's a satisfying sum. Besides, you can line your pockets with a tidy income whether you win the pot or not.

Sisters of Oz WowPot

Sisters of Oz Wowpot is a progressive jackpot game that sees a collaboration between progressive slot leaders Microgaming and Triple Edge Studios. The game boasts a “Wizard of Oz” theme but with sassy Witches conjuring up the magic and the wins. The main Wowpot progressive jackpot starts at a whopping £2 Million in this game, which is double what the aforementioned MegaMoolah starts at! There are also frequent free spins, wilds, scatters, jumbo symbols and stacked symbols to keep you enthralled during gameplay. Sisters of Oz WowPot looks amazing and is one of the most popular slot games in the WowPot series.

NetEnt

NetEnt is another major force and an innovative Scandinavian developer. The company from Sweden started in 1996 and is responsible for creating a vast range of online slot machines that feature dozens of online casinos. Licensed titles include gems like South Park and Aliens. In addition, NetEnt has created some of the most well-known slots like Gonzo's Quest and the famous Starburst. They both feature remarkably realistic visuals and highly dynamic gameplay.

Microgaming

Microgaming is a recognisable name in the industry, with hundreds of slots and casino games to its name. Microgaming holds the world record for a jackpot payout of over £13 million playing the progressive jackpot slot machine Mega Moolah. Microgaming also has the MPN poker network and produces multiplayer community games. Among the numerous releases by Microgaming, Mega Moolah stands out as a prime example of the quality and creativity of the developer's games. Major Millions slot comes in at a close second place and is another big hit. Microgaming's network of progressive jackpots has paid out more than £450 million over the years. 

IGT 

IGT has had a very successful past and built a solid reputation. One of the most impressive creations IGT offers allows players to adjust the graphics settings on games to better suit internet speed and the device itself. Subsequently, players enjoy a smoother, more fluid game without facing frustration, lag or disconnection. In addition, the slots have wide-ranging betting limits, with lower minimum limits and more massive maximum payouts per pay line.

Blueprint Gaming

While not as popular as Microgaming and NetEnt, Blueprint gaming is another developer creating a wide range of slot games, including progressives. So next time you think of playing jackpot slot games, don't forget to consider playing Buffalo Rising and Spinal Trap, two progressive slot titles.

Playtech

Playtech is well known for its range of licensed casino games. Playtech's catalogue includes games based on Monty Python's Spamalot, Gladiator, The Mummy, and Marvel-branded slot games. The smash-hit movies have led Playtech to develop more high-quality slot titles based on iconic heroes like The Avengers, Iron Man, Wolverine, The Hulk and Thor. The games are integral in attracting the younger crowd to play slots online.

Must Fall / Daily Drop Jackpots

Must Drop and Daily Drop jackpots are essentially progressive jackpot slots that payout before a specific time each day. As the deadline approaches, the jackpot gets more significant, as do the chance it will drop and deliver a prize to a lucky player. Must Drop and Daily Drop jackpots work similarly to other progressive jackpot slots. A percentage of every player's bet at every participating online casino that offers the game adds to the jackpot prize pool. The more stakes, the more the jackpot prize increases until someone wins it. Once that occurs, the jackpot resets, and the process starts over. Must Drop and Daily Drop jackpots guarantee the prize pool pays out before a particular time each day.

Jackpot King Network Progressive Slots

Jackpot King games are a series of linked games from Blueprint Gaming that share a jackpot prize. You need to trigger the jackpot round by landing 5  of the Jackpot King symbols on the same spin. Then, play the mini-game to try and land the big prize pools! Jackpot King progressive slots include popular Deal or No Deal, Slots O’ Gold, Reel King, Ted, Fishin’ Frenzy and many, many more. Jackpot King slots are available at the most reputable, UKGC licensed casinos, so you won't find them hard to find. All casinos we recommend on this page offer a large choice of Jackpot Kin slot games.

Progressive Vs. Fixed Jackpots - What's The Difference?

Fixed jackpots generally pay out frequently and randomly with any bet amount. Progressive jackpot slots work differently. You need to wager on all the pay lines to stand a chance of winning the jackpot. The higher the coin values you wager, the better the chances of winning the highest jackpot payout. Conversely, wagering low coin values will also stand a chance of winning a jackpot as long as you bet on all the paylines. The latter earns a lower jackpot payout; nevertheless, it is always welcome!

On the other hand, playing with minimum coin values on a progressive jackpot slot is less favourable, and the possibility of winning increases. The average payouts are marginally lower than fixed jackpots; however, the excitement increases and the anticipation of winning is always there. Comparing progressive jackpot slots to fixed ones is like comparing a sports car to a city car; both have their place, and both are useful. 

Players looking for higher stakes should opt for progressives, and those in search of better probabilities should choose the flat top jackpot slot. The average payouts of progressives are much lower than that of regular jackpot slots since a portion of the takings goes into the pot. Fixed jackpots have a higher return to player percentage, which translates into better chances of winning the jackpot.

Making The Most of Progressive Slots - Our Top Playing Tips

Progressive jackpots are some of the most exciting games UK online gambling sites have to offer. below are some tips that we recommend taking into consideration when playing this type of game:

  • Choose Your Casino Carefully: Only play at UKGC licensed casinos - especially the ones we recommend that have been heavily vetted to ensure they have the friendliest player terms. Before you start at a new casino, check to ensure that it pays the jackpot amount in one lump sum and not in long instalments.
  • Play Higher RTP Slots: It’s a good idea to check a game RTP % and variance below you start. Our Slot reviews will help you with that or you can find this information in the paytable of the game. Sometimes, progressive jackpot games have a lower-than-average RTP % it’s worth playing those with the highest RTP.  There’s more information about RTPs and jackpot slots on our best RTP slots page.
  • Do Your Homework: Before you go all guns blazing, check the games for a few rounds to see if you like it. Always read how to play a game to have a better chance of winning. It’s worth noting here that sometimes, players must play with the maximum bet to be eligible for the highest paying prize
  • Jackpot Trackers: Keep an eye on progressive jackpot trackers and do a quick calculation. If a jackpot has just been won, the chances are you won’t be winning anything substantial any time soon on that game, therefore look for games that haven’t been won in a while / have a juicier jackpot that might be ripe for dropping!
  • Play With A Cool Head: Remember that all casino games and slots are a game of chance and luck. There are no strategies or a miracle formula that will help you win the jackpot (unfortunately). If it was easy to win, there would be no point in these games at all! Also, remember to stick to your budget only play with money you can afford to lose.
  • Explore New Games: don’t get preoccupied with just the one jackpot because there are so many out there. We recommend regularly discovering new games to try. Progressive jackpots regularly appear in new formats and variations which can offer a new, fun twist on an older game but interestingly, they can be found in other casino games, such as Live Casino games as well!

Biggest Progressive Jackpot Slot Winners

Companies such as eCogra and iTechLabs check every game regularly to ensure the game's payout is fair and square (according to the games stated RTP %) and randomly. All games are built with what's known as a "Random Number Generator" which is what these companies check. RNG's ensure all games payout entirely at random. Games can't be tampered with or rigged - not by casinos' employees or by players with any software. Online casino games are highly sophisticated yet highly regulated - so you know they are fair!
