Progressive Jackpot Slots

(editor) | Updated:

Offering mind-blowing jackpots of millions of dollars, progressive slots are among the most popular casino games on the market today. Although experienced players know there are plenty of games with a much lower house edge, such as blackjack and poker, they still flock to popular networked progressives. Their motivation is obvious: no other game can provide such high payouts.

Progressive jackpots started appearing in some slot machines across Las Vegas several decades ago, but their jackpots were fed only by bets on specific machines, and the payouts rarely went beyond $10,000. This type of slot machine is still widely spread in brick-and-mortar casinos all over the world, but its popularity has slightly declined since the rise of web-based casinos. Today, progressive video slots attract thousands of online players each day and often accumulate jackpots of more than $10 million. Meanwhile, players know that with a little bit of luck, they can collect life-changing winnings with a single bet worth only a few dollars.

How Progressive Jackpots Work

Unlike most slot games where the jackpot is fixed, progressive slots have incrementally increasing jackpots that grow with every bet placed on them. The idea is quite simple: a small percentage of every wager feeds the pool of money until one lucky player hits the winning combination that triggers a jackpot payout. Logically, the highest jackpots can be won on games with the highest bets and the most players. Several interesting things should be taken into consideration before investing your time and money into a progressive game.

Qualifying

One of the essential things players need to learn is how to qualify for the jackpot, because not every bet on a progressive slot can lead to winning this attractive payout.

Jackpot Meter

There is another important component in these games. Once the jackpot is won, the amount of the highest payout resets to the level at which it started.

Odds and Expected Return

The odds of hitting a progressive jackpot on a slot game are extremely small, often smaller than winning the lottery, and if we remove the jackpot from the calculation, the house edge becomes much higher.

Most of the largest casino game developers have added slots with progressive jackpots attached to them. Yet, the majority of slots in any given online casino do not fall into this category, so to find a good progressive game, you may have to do proper research and check more sites than you would like to. Still, there are several progressive games that are just as lucrative as they are fun to play. Designed by some of the most respected companies in the gaming software development industry, they attract huge crowds with the promise of once-in-a-lifetime winnings.

mega moolah logoWith a jackpot starting at $1 million, Mega Moolah is among the most generous and popular slot games around. It is developed by Microgaming, one of the giants in this industry, widely known for the many progressive jackpot games it has in its impressive portfolio. Interestingly, Mega Moolah is considered a penny slot, because the minimum bet starts from $0.01 per line and reaches $0.05, while the max bet is only $6.25. Mega Moolah is linked with other games and is part of Microgaming’s large Progressive Jackpot Network. This is the reason why the payouts are often above $5 million.

Absolootly Mad: Mega Moolah logoWith Microgaming’s Mega Moolah becoming a favorite title for players chasing progressive wins, the company decided to expand the number of games linked to the Mega Moolah prize pool. That is why players have received the chance to play a cool game such as Absolootly Mad: Mega Moolah and compete for the same generous progressive jackpot, which has turned numerous players into millionaires.

Leprechaun’s Luck

Leprechaun's Luck logoThose who believe in lucky charms will most likely appreciate Playtech’s slot Leprechaun’s Luck, which offers players the chance to sweep a generous progressive jackpot prize. The slot, which was originally released by Ash Gaming, spreads across five reels, while winning formations can land on 20 fixed paylines. The design of the game is rather simple, inspired by the traditions of Irish luck.

While Leprechaun’s Luck gives its players the chance to win a generous progressive prize, the slot can also be very rewarding through its additional bonus features. When it comes to the size of your bets, you are able to wager between $0.20 and $20 per spin. That said, increasing your stake can positively affect your chances of winning the jackpot.

Funky Fruits

Funky Fruits logoThe next progressive slot we recommend is Funky Fruits by Playtech. Despite being rather simple, this progressive title can be very entertaining and rewarding. As the name suggests, it has a fruity theme, with various delicious fruits appearing on the five reels of the slot. However, instead of paylines or multiple ways to win, Funky Fruits offers payouts for clusters of five or more identical symbols on adjacent reels.

Depending on the number of symbols forming a cluster, different fruits pay different amounts. While there are no special symbols or bonus features, Funky Fruits offers a generous progressive prize that can be won thanks to the cherry symbol. The game has a rather small bet range, but that is because the bet size determines the percentage of the jackpot prize you can receive if you get extra lucky. The lowest amount you can bet is $1, while the maximum is $10.

Aztec's Millions logoThis progressive slot by Realtime Gaming (RTG) is a rather interesting jackpot title, as it offers a generous progressive win, with the seed starting at $1,000,000 when the jackpot is won by a lucky player. For many years, players believed there was no point in playing the slot, as it would not release the big prize for several years. In 2021, however, the major prize, which was exceeding $4 million at that time, was finally won, proving there is indeed a chance to sweep the jackpot pot of Aztec’s Millions.

The slot spreads across five reels, with symbols including Aztec idols, amulets, the Aztec king, and the Aztec queen. The game has 25 fixed paylines, with most symbols awarding a payout when matched three or more times on a winning line. Several high-paying icons can grant a payout even when landing only twice on a payline, while the queen can offer a cash reward even for a single symbol at the beginning of a winning line. As for the bet size, players have no choice, as the game has an obligatory bet per line of $0.20, making the total bet on every spin $5.

Choosing a Casino to Play Progressives

jackpot casino imageAlmost all online and land-based casinos offer their customers attractive progressive jackpots. At most sites, you will find at least five different progressive slots, while at some casinos, you can choose from over 30 titles by different providers. There is a great variety of progressives that cater to all types of players, and if you are looking for a good casino where you can play for the jackpot, stick to sites with larger and more diverse collections.

Of course, players who are new to online gambling, or who so far have played at a limited number of gambling sites, will want a place with an impeccable reputation. Safety and reliability are extremely important, especially when it comes to betting on progressive games, because players tend to make larger deposits and higher bets than usual. In addition, you will need a trustworthy casino that will pay out the jackpot as quickly as possible, no matter how huge it is. Speaking of jackpot payouts, players should also check whether the casino limits withdrawals or makes an exception to the max cash-out limit when a progressive jackpot is won.

Progressive Jackpot Withdrawal

progressive jackpot withdrawalWinning the jackpot is undoubtedly an incredible experience. For most players, this is an unforgettable moment even if the amount they win is only $100. But it is the huge jackpot of several million that will blow your mind and change your life forever. It is an overwhelming experience for casinos, too. Often, they cannot afford to pay out such huge amounts of money. That is why jackpots, especially in online casinos, are usually paid out by the game developers.

The more important aspect of jackpot withdrawals, however, is how your winnings are paid. Many large brick-and-mortar casinos give players a choice: they can collect the entire prize at once, or they can receive annuities over the course of 10 or 20 years. The majority of online casinos, if not all, have fixed cash-out limits based on a weekly or monthly basis. In other words, you cannot withdraw more than $5,000 or $10,000 per week, for instance. While this is not a problem with small wins, it certainly becomes an issue when talking about jackpot withdrawals.

Retrieving a huge win from an online casino may take months or even years if the gambling operator maintains a strict withdrawal policy. Fortunately for jackpot hunters, many casinos make an exception to this rule and will pay you in full if it is a progressive jackpot win.

Bet Sizes

slots paylines imageThere are not many strategies or systems you can use to improve your winning chances in progressive slots. One of the most important things, however, is to check the amount of money you need to bet to qualify for the jackpot. Many progressives allow you to play for the big prize only when placing max bets or at least the maximum number of coins. Different games have different rules, so before putting your money in a particular slot, you should check its pay table and rules.

For instance, some jackpots can be unlocked only when playing with max bets, but others can be won during a randomly activated bonus game. Of course, the bet size is essential, as it may decide whether you end your play session as a millionaire or lose every penny you have. The best chance of winning the jackpot is if you are betting on all pay lines and, in most cases, the maximum number of coins.

To continue playing for longer without wagering your entire budget in five minutes, play with low-value coins. Another good strategy is to change the currency you play with if the jackpot remains the same amount after conversion. For instance, you can bet $10 per spin, and in Euro the qualifying bet will still be €10. However, while the jackpot in U.S. dollars is $1,000, in Euro it will be €700. This means that a bet in U.S. dollars has a lower real value, yet by placing it, you can win the same jackpot offered to Euro players.

The Biggest Progressive Jackpots Won

progressive slots imageThe highest progressive jackpot payout ever recorded is $39.7 million. It was hit in the Excalibur Casino in Las Vegas on one of the most famous slot games, IGT’s Megabucks. Until recently, Megabucks was available only as a physical slot machine across numerous gambling facilities around the world, but IGT has also added it to its portfolio of online games. Online slots, on the other hand, still have not reached such high payouts, but they are quickly gaining popularity and making more and more players instantly rich.

Mega Moolah, for instance, is known for the big payouts given quite regularly to players from all over the world. In 2015, the game often called “The Millionaire Maker” gave a British army soldier £13,213,838.68. This happened at Betway, and the soldier, J. Heywood, managed to get the jackpot by placing £0.25 bets. Mega Moolah has made many people rich – in 2016, Canadian Marcus Goodwin took home CA$11,633,898, while just a few months before that, a Maori man in New Zealand pocketed NZ$10,144,395.82.

Another mind-blowing payout was the unexpected win of €17,861,813 in January 2013 at Paf Casino. The lucky winner was an anonymous Finnish man who got the right combination of symbols while playing NetEnt’s Mega Fortune. Previously, in 2011, that same game paid out €11,736,228 to a Norwegian student who was trying his luck with free spins. Other slots from NetEnt have also been generous – on 23 November 2012, another unnamed Finn became richer by exactly €8,636,041.54 while playing Arabian Nights. One of the slots by the same developer that is known to be won regularly is Hall of Gods. The biggest payout registered from it is €7,820,888, but players are hitting the jackpot approximately twice a year.

The highest mobile jackpot payouts have been at Microgaming’s Mega Moolah slot. On 28 August 2016, a woman playing the popular game from her mobile phone managed to hit the jackpot, taking €7,968,311.26. At the time, this was the biggest mobile win ever recorded, but this changed in less than a year when in April 2017, a mobile player at Tipico Casino became an instant millionaire by claiming the incredible sum of €8,012,153.35.

Is there any strategy I can use for my progressive slot betting sessions?

Asked by: James | Asked on: 2023-06-12
Answered by: Dan | Answered on: 2023-06-14

Slots are games of pure chance, and there is no way to beat the house when luck is not on your side. This holds true for both non-progressive and progressive jackpot slots. Although no strategy can guarantee a big win, you can follow a few guidelines the next time you spin the reels of a progressive slot.

First, always bet the maximum amount if that is required to qualify for the progressive jackpot. If the jackpot prize is randomly triggered and does not depend on bet size, place reasonable wagers that let you play more rounds. Set a loss limit and stop once you reach it, even if you have not hit the jackpot. Also consider the current jackpot amount; avoid playing right after the top prize has been won, when the pool has barely grown beyond the seed value. Finally, check the RTP and variance of any progressive slot you are considering. A solid RTP and low-to-medium variance are preferable to a slot with low RTP and high variance.
