An Introduction to Jackpot Slot Games

Over the last two decades, slot games have become some of the most-played games at online casinos and bingo sites. They offer a multitude of themes and special features, ranging from the humble three-reel slot (which is similar to a classic fruit machine) and five-reel 3D slots with dazzling graphics and animations.

But, software companies like Playtech, IGT, and Microsoft are well aware that seasoned players are often more interested in how much money they can win. And if, like them, you’re seeking games that have the potential to award huge cash prizes, you’re best off playing a jackpot slot.

Jackpot slots typically feature one or more progressive jackpots that grow in value until one lucky person triggers the winning combination to release the pot. Some of these games are more likely to pay out to those who wager with higher bets while others can randomly award their jackpot to anyone who plays the game.

Although there’s no secret formula to winning, you’ll have the upper hand if you understand more fully how jackpot slot games work. For this reason, we’ve created this guide which aims to tell you all you need to know about playing jackpot slots online.

Plus, our website shows you a constantly updated list of the best places to play your favourite slots and other games (such as bingo, scratch cards, table games, card games, video poker, and live dealer games).

We’ve sourced the UK’s most popular and ground-breaking new online casinos and bingo sites, and carried out full reviews so that our readers can quickly and easily find their perfect playing partner. And, as our reviews also cover what types of games are available at each site, it won’t take you long at all to find those that stock an excellent selection of jackpot slots!

What are Jackpot Slot Games?

As you may already be aware, there are many different types of online slots to choose from, and as technology is constantly advancing, so too are the types of games that are created by the world’s leading software manufacturers.

There are three-reel, five-reel, six-reel, mobile, 3D, and jackpot slots, as well as all of the other innovative games that fall somewhere in between.

Not even jackpot slot games belong to one particular game type as the way that their jackpots work can differ greatly.

The four types of jackpot slot that you’re most likely to encounter while playing at online bingo and casino sites are standalone, networked, multiple, in-house, and non-progressive. Below, you’ll find a brief overview of how each one works.

Standalone

Standalone progressive jackpot slots use one jackpot which is funded by a percentage of all wagers placed on it by players, and the jackpot is not linked to any other game. The value of the pot rises with each new bet that’s staked on it, and once it pays out, it resets to a minimum fixed amount. Although standalone games tend to offer smaller pots than networked and linked slots, they still have the potential to award generous sums of cash.

Networked

Networked progressive jackpot slots such as the world-famous Mega Moolah are available across a network of online casinos which use the same software platform (e.g. Playtech or Microgaming). Because such large numbers of casinos are involved, with each one having thousands of players, networked games frequently offer the biggest pay-outs due to the vast numbers of bets that are constantly being placed on them.

It’s not uncommon to see networked jackpot slots boasting pots that are worth £1m or more.

Multiple

Multiple progressive jackpot slot games do pretty much what they suggest. They offer more than one (and typically three) jackpots which vary in size.

In-House

In-house progressive jackpot slot games are games which are linked together either at one online casino or several casinos that belong to the same operator.

Non-Progressive

Some games are advertised as jackpot slots but they are not progressive, i.e. they do not grow in size. A good example is Cirque Du Soleil – Kooza by Bally Technologies. Kooza comes with four pots called Mini, Grand, Colossal, and Tres Magnifique, and their size is determined by how much a player bets. Pots of this type are commonly referred to as fixed jackpots.

Popular Jackpot Slot Games and How They Work

Mega Moolah and Mega Moolah Isis

Mega Moolah and Mega Moolah Isis are two of the most popular jackpot slots in the entire world. The only difference between them is the theme, with the former favouring an animal safari and the latter opting for an Egyptian goddess theme.

The jackpot is shared between the two games, and the way in which you can win it is identical too. There are four jackpots to play for – Mini, Minor, Major, and Mega – which you can see rising at the top of the screen. Each pot seeds (i.e. resets after being won) at a different amount. The Mini seeds at £10; the Minor seeds at £100; the Major seeds at £10,000, and the Mega seeds at £1m.

The pots can be won via the Mega Moolah jackpot game, which can be randomly awarded on any spin. You spin a wheel to find out which prize you’ve won, and as you might expect, there are more winning segments for the smaller pots than the larger ones.

As well as mega sums of cash, the Mega Moolah slot also offers players free spins and extra winning opportunities through wild substitutions.

Mega Fortune

Mega Fortune is a five-reel progressive slot with twenty-five paylines, and its theme revolves around a millionaire lifestyle with paytable symbols that include luxury yachts, gold watches, limousines, and bottles of champagne.

The game has a free spins feature plus a Wheel of Fortune Bonus in which you can earn instant cash prizes, access to other prize wheels, and one of three progressive jackpots (Rapid, Major, and Mini). The largest pot seeds at £250,000, and according to online jackpot trackers, the biggest pot pays out an average of £4m per win roughly every ten weeks.

Millionaire Genie

1,001 Arabian Nights and the story of Aladdin is the inspiration for Random Logic’s popular slot, Millionaire Genie. It comes with a free spins feature that includes extra wild symbols, and a Genie’s Palace Bonus which gives you a cash amount and a win multiplier.

The good news is that the progressive JP is awarded at random, so you don’t need to spin a particular symbol combination to win it. However, the higher your stakes, the better your chances of scooping it.

Major Millions

Major Millions is five-reel jackpot slot by Microgaming, and it commonly features at online casinos for UK players. It uses a humorous military theme, and lets you win cash prizes with symbols such as ammunition, binoculars, tanks, warships, fighter planes, and the army major’s cap.

Land five wild symbols on the fifteenth payline, and you’ll be taking home a minimum of £250,000!

Tunzamunni

Tunzamunni by Microgaming uses classic fruit machine symbols such as bars and 7s. It’s a three-reel game with just one payline and no special features, but you can still score a tasty progressive jackpot while playing it if you get a silver 7, a red 7, and a blue 7 from left-to-right. The only qualifying criteria for this particular progressive jackpot is that you must be playing with the maximum number of coins (N.B., five) which equates to a maximum stake of 25p.

Age of the Gods

Age of the Gods is the first in the series of Playtech’s Age of the Gods jackpot slots, and all of them share a progressive pot, although each one boasts individual special features such as Pantheon of Power.

Age of the Gods has four different jackpots – Power, Extra Power, Super Power, and Ultimate Power, and they can be randomly awarded on any given spin.

Gladiator Jackpot

Gladiator Jackpot is a Playtech game which is based on the famous film of 2000 starring Russell Crowe and Joaquin Phoenix. Wild symbols, scatters, and free spins, as well as video clips make it an exciting title to play on your desktop or mobile, but if you want to take home the biggest reward of all (the PJP), you’ll need to trigger the bonus game with three helmet symbols on Reels 2, 3, and 4. Find nine gold helmets in the bonus game, and the jackpot’s all yours!

Beach Life

Enjoy some fun in the sun with Playtech’s Beach Life jackpot slot, and you could be booking a dream holiday for real. To fly home with the game’s PJP, you’ll need to land five sun symbols on the twentieth payline.

The Odds of Winning

Your chances of winning with a jackpot slot are affected not only by chance, but also by the game’s volatility and RTP (Best Payout Slots). Volatile jackpot slots are higher risk than low-volatility slots as they tend to award larger pay-outs on a less frequent basis. The RTP is the Return to Player Rate, and it indicates how great the house edge is. The higher the RTP, the better for the player.
