What is a progressive jackpot slot machine?

Charles Fey invented slot machines in 1895. It’s almost 100 years later, in 1986, that IGT (International Gaming Technology) rolled out the first slot machines with progressive jackpots in land-based casinos around the world. This feature pleases many players thanks to the huge winning potential it holds. But what does it consist of exactly?

Madness Bonus answers the most common questions about progressive jackpot slots:

What are the characteristics of a progressive jackpot slot machine?

At first glance, a progressive jackpot machine may seem relatively identical to a regular slot machine. It can have a standard number of reels, free spins, random base game features, etc. In short, fairly traditional features… With one (big) exception: the progressive jackpot.

What differentiates a classic slot machine and a progressive jackpot slot machine?

The main difference between a classic and a progressive jackpot slot machine is indicated in the name of the latter. It is obviously the progressive jackpot feature that makes it so interesting and gives it unparalleled potential. On a classic machine, you can expect to win big during free spins. On this other type of machine, if you hit the jackpot, you could win really big.

What exactly is a progressive jackpot?

On a traditional slot machine, only a big base game hit or very good free spins can make you win big. This is also the case on a progressive jackpot machine, but that’s not all. On these slots, each of your bets increases a jackpot that is displayed above or to the side of the slot. Sometimes there are even several jackpots, which can be won in different ways.

From one machine to another, the way to win the jackpot can vary. Sometimes it’s during free spins, sometimes it’s by landing a special symbol, and sometimes it’s during a random feature. Once won, this jackpot resets at a low value and increases as players bet on the machine.

The various progressive jackpot slots

You have chosen a casino to play on, you have deposited money into your player account and even claimed your welcome bonus. That’s great. Now all you need to do is check out our favourite progressive jackpot slot machines. Many online casino game providers have created machines belonging to this category. Among these studios, we can notably mention Microgaming, Yggdrasil, iSoftBet, Playson, Hacksaw Gaming or even Betsoft.

Let’s cut the chatter: discover below 6 progressive jackpot machines we enjoy playing during our casino sessions.

Mega Moolah (Microgaming)

Behind its dated or even old-fashioned look, Mega Moolah is a slot machine with incredible potential. This game features one of the biggest progressive jackpots around the world. Created by Microgaming in November 2006 (which explains its appearance) this machine paid out 19.4 million euros in April 2021 to one lucky player. Although the main attraction of this machine is its jackpots, it also has a free spins feature. You receive 15 free spins with a 3x win multiplier. There are four jackpots in this machine: Mini, Minor, Major and Mega. This game has a RTP of only 88.12%, which is very low for an online slot machine.

Holmes and the Stolen Stones (Yggdrasil)

Holmes and the Stolen Stones is an Yggdrasil slot that was released on September 10, 2015. As the name suggests, it is based on the famous fictional British detective Sherlock Holmes. He goes in search of lost gems. These same gems are special symbols that you need to collect in order to access a bonus that allows you to potentially pocket one of the jackpots. Once in this bonus, you must collect 5 identical coloured gems to win the corresponding jackpot. This machine has already paid one player 48,000€.

Celebration of Wealth (Play’n GO) + Beast of Wealth & Temple of Wealth

While several game providers had already created their progressive jackpot machines since a long time, Play’n GO has been slow to catch on. The studio corrected this in September 2020 by releasing three machines belonging to this category. Celebration of Wealth is one of them. It’s a beautiful Asian-themed slot machine. Four jackpots (Mini, Minor, Major and Grand) sit atop four of the five reels. During base game, between 1 and 5 reels can turn into Gold Reels. When a wild symbol falls on one of these reels, the jackpot feature is triggered.

If you like this progressive machine from Play’n GO, check out Beast of Wealth and Temple of Wealth. You’ll enjoy them just as much.

Jackpot Raiders (Yggdrasil)

Released in May 2019, Jackpot Raiders is a slot machine created by the famous game provider Yggdrasil. This slot features 5 jackpots called Forgotten, Rare, Mythical, Ancient and Legendary. In order to access the jackpot feature, you need to collect 5 identically coloured map pieces. Once you have done this, you will receive 10 free spins and a Jackpot gem of the same colour as your map pieces. As you can see, in order to win a jackpot, you need to collect 5 gems of identical colour during the free spins. This game has a rather classic RTP of 96.30%.

Mega Fortune (NetEnt)

You probably know NetEnt for its latest slot machines that are all very good looking. Despite its rather archaic appearance, Mega Fortune might surprise you with its huge potential. This 5 reel 25 paylines slot offers three distinct jackpots: the Rapid, the Major and the Mega, which is the most interesting. A 40 year old Finnish player won a whopping 17.86 million Euros on September 24, 2011.

Jackpot Express (Yggdrasil)

Jackpot Express is an Yggdrasil slot that takes you on a cruise on a steamboat. The crew members of the ship are premium symbols. The captain is obviously the best symbol. There are three jackpots here. First there is the Mini, which is the smallest. Then comes the Secondary, which is starting to become more valuable. Finally comes the Major, which is the highest paying. The RTP of this online casino game is 96.20%.

The originality of this machine lies in the fact that the jackpots are obtained by spinning a wheel of fortune. You spin a first wheel, which can take you to the level 2 wheel. On level 2 is the Mini Jackpot, multipliers and a level up arrow. On level 3 is the Secondary. Level 4 is where the so coveted Major jackpot can be found.
