Mega Moolah

Mega Moolah is probably the most well-known progressive jackpot slot in the world. In 2015, Mega Moolah made headlines when a UK Betway player won the massive jackpot prize of over £15 million. The game comes with a cool safari theme, and it’s played on a simple grid with five reels and 25 paylines.

There are four progressive jackpot prizes, and they can be triggered at any time during gameplay. The special bonus wheel will appear on screen, and you’ll simply need to spin it to see if you’ve bagged one of the progressive jackpot prizes. Mega Moolah is available at lots of top online casinos including LeoVegas.

Joker Millions

Joker Millions takes inspiration from retro-style slot games, and you’ll be looking out for symbols like cherries and bells to land small wins. But if you want to stand a chance at the biggest prize, you’ll have to wait for a Joker symbol to land on the grid. The Joker awards the respins feature, and the reels will continue to respin until no more Jokers land. If you fill up the entire grid, you’ll be awarded the progressive jackpot prize.

During normal gameplay, you can win by matching symbols on one of the 25 paylines, plus there are chances to get multipliers on your wins. UK casinos with no deposit bonuses often exclude this game from being played with bonus funds, but it's worth checking out if it's available to you.

Mega Fortune

Mega Fortune is a five-reel slot with 25 fixed paylines and an impressive RTP of 96.4%. To win the jackpot, you’ll have to get three or more of the special scatter symbols on a payline, and then the bonus game will open up. You’ll see three fortune wheels, and if you land on an arrow on all three of the wheels, you’ll bag the biggest jackpot amount.

There are also other chances to win by matching at least two of the standard symbols on one of the 25 paylines. This game is available at all top NetEnt casinos in the UK, such as Pub Casino.

Book of Atem WOWpot!

The top jackpot prizes on the WOWpot! games can be just as big as the Mega Moolah slots. Book of Atem comes with a jungle theme, and you’ll have to visit the ancient ruins to hunt for wins. There are four jackpot prizes, and to get into the jackpot round, you need to collect the bonus symbols. Once you have enough of them, the prize wheel will display on the screen, and you can spin to see if you’ve won the jackpot.

Lots of the best UK online casinos offer Book of Atem WOWpot!. For example, you can play at BetMGM UK.

Mega Moolah Isis

Ancient Egypt is one of the most popular slot game themes, so it’s no surprise that there’s a Mega Moolah game based on gods and pyramids. Mega Moolah Isis is one of the best progressive jackpot slots in this series, and just like the original slot, it can hold jackpot payouts of up to eight figures.

To win one of four jackpot prizes at the best online slots sites, you’ll have to wait until the money wheel triggers randomly, and spin to see where it lands. Even if you’re not lucky enough to win the big prizes, you can still look forward to generous payouts and features like free spins.

How Progressive Slots Work

There are two main types of jackpot slots that you’ll come across at online casinos: fixed jackpots and progressive jackpots. Fixed jackpots are exactly what they sound like - jackpot amounts that stay the same at all times. The maximum amount you can win on fixed jackpots is usually determined by your stake value. Progressive jackpots, on the other hand, increase all the time, so they can reach truly massive amounts of money,

On progressive jackpot slots, a small percentage of every losing bet contributes towards the prize pot, which is why you can sometimes see it increasing in front of your very eyes. These games are usually linked across multiple casinos that carry the game, meaning that thousands of people play progressive slots every day, leading to huge potential payouts.

The mechanism for triggering the jackpot win is slightly different on each slot game. We’ll go into more detail about this later, but for now it’s enough to understand that on some slots you can trigger the jackpot randomly on any spin (even if there are no winning combinations), while on others you’ll need to get a specific combination of special symbols.

Tips For How To Win Progressive Jackpots

The first thing you need to understand is that progressive jackpot slots at reputable online casinos all use Random Number Generator technology. This means that the games are fair, and there’s nothing you as a player can do to determine the outcome of the spins. That said, there are a few things you can do to give yourself a better chance of a jackpot win.

The first thing to do is check how much the progressive jackpot is standing at, before you play. If you’re aiming for a truly giant win, you might want to wait until the jackpot amount is very big. The other option is to choose a game with a smaller progressive jackpot prize (for example four figures rather than seven), as these tend to drop more often. Some new casino sites even have daily progressive jackpots, and even though these might not be huge, you’ll have a better chance of winning, as they have to drop every single day.

It’s also important to understand how the game works. Many progressive jackpots can trigger randomly on any spin, while others require you to land scatters and spin a prize wheel, or fill up the grid with special symbols to win the top prize.

If you’re comfortable doing so, you might want to increase your stake amount, as some slots link the jackpot prizes to your spin value, so by playing for bigger amounts, you stand a chance to win more money.

Finally, it’s important that you play responsibly at all times. You should set a personal limit and stick to it, or use the online casino’s built-in tools to set deposit, loss, or wagering limits. You can also set session time limits or a cooling off period to help you stay in control.

Best Payment Methods For Progressive Slots

Before you can play any online progressive jackpot slots, you’ll need to add money to your casino account. Most UK sites offer a wide variety of methods that you can use, and each of them has its own pros and cons.

The most common method that most UK players tend to use for online casino deposits and withdrawals is a standard bank card (Visa or Mastercard). This is probably the simplest and most convenient way to transact, and it’s extremely secure. Just keep in mind that withdrawals might take a few days to reach you. If you don’t want to use your card, you can use bank transfer casino payments to deposit and withdraw at most casino sites, but this method tends to have much longer timelines.

E-wallets are also popular at UK online casinos. For example, you might be able to use "Skrill casino Neteller casino, or PayPal casino UK payments. All of these support quick and secure payments, and don’t require you to share your bank details with the casino. One downside to e-wallets like Skrill casino deposits is that they’re not always accepted for claiming bonuses, so you might prefer to use your bank card when you’re claiming offers.

Some UK online casinos also offer mobile-specific payment methods like Google Pay or Apple Pay casino UK, which are only available when you use your mobile browser or the best casino apps.

Progressive Jackpot Casino Bonuses

A great way to kick off your online casino experience, and maybe even stand a chance at winning a progressive jackpot, is to claim an online casino bonus for new players. For example, as soon as you sign up and deposit, you might be eligible for a big deposit match, or some free spins to use on a popular game.

Bonuses aren’t just for new players, though, as regulars can also get offers like cashback, reloads, free spins no deposit bonuses, and entries into prize draws and tournaments. Your online casino of choice might even have a loyalty or VIP program, to award the top-tier players with bespoke bonuses.

One thing to keep in mind is that all online casino promotions come with terms and conditions, including rules about which games the bonus cash can be used on. Before you claim an offer, you might want to read the exclusions in detail, as in some cases you might not be able to use the bonus money on progressive jackpot slots.
