More about Jackpot Slots

Amid some of the more popular game styles, we find two main divisions of slots, namely, classic slots and video slots, into which you can divide all of the various genres, themes and styles of slot games available for play online.

If you go to a brick and mortar casino, you will usually see certain groups of slots gathered together with a large colourful display showing a massive accumulating figure over the top of those selected machines.

Here, all the grouped machines are a part of the same network and contribute to the climbing total. Not only this, but you will find that the same machines on other casino floors around the country/world will all be linked to the same pot, each machine adding to the massive prize as the reels are spun. So, if any of those machines hit the jackpot, the amount will be reset to a lower figure across the network.

The same method and principle are followed through to the online casino world. Often progressive jackpots are linked to all games or groups of games within the same network, so each wager spent on those games around the world will add to the accumulating total available to be won.

A classic example of such a network of games is the MARVEL branded slots from Playtech. Whether you are playing Iron Man 3, Incredible Hulk or Wolverine, or any other MARVEL slot linked to a progressive jackpot, each player across the world will add to the win with their wagers and could at any moment win the entire pot.

Common features of Jackpot Slots

Though the themes and genres may differ from Jackpot slot to Jackpot slot, the nature of the game behind the scenes may be very similar. Some of the common features found behind progressive network jackpot slot games include:

Lower Return to Player Percentage (RTP)

The laws of supply and demand operate as well within the online gambling industry as they do in any other capitalistic market. Progressive Jackpots are extremely popular and draw multitudes of players, as many people are found awestruck by the possibility of potentially winning a life-changing amount of money.

It would be very expensive if casinos had to pay out these types of jackpots too regularly though, so certain mathematical adjustments are made to alter the frequency of the pay-outs. These two combining factors usually lead to Jackpot Slots having lower RTPs than other standard slots. Often the return to the player over the lifetime of a slot machine is around the 85% to 90% mark, whereas other standard slots may average at 95% to 97% RTP.

Higher Variance

Progressive slots tend to have a longer arc between high payouts. Sometimes, hundreds of thousands of spins must occur before the jackpot is won. For this reason, patience is needed in order to take anything home from these machines.

Multiple Currency

Because progressive jackpot networks extend across the world, these top prizes often convert over to different currencies and will often display in the currency you have selected to play in. The value remains the same, but you will find that the figure in Euros, for example, will not be the same figure reflected in Norwegian Krone.

Multiple Progressive Jackpots

In the online gaming industry, there are a large number of Jackpot games that offer more than one progressive win in a single game. Often, there will be three wins up for grabs, usually marked as a minor, intermediate and major jackpot. These smaller wins are available to those who do not play the maximum bet, in order to encourage players of all spending levels to enjoy a flutter.

Tips to help you in your quest for the Progressive Jackpot

You can start by reading our Progressive Jackpot guide and learn more about some tips and tricks on how to win the jackpot.

No Guarantees

Firstly, do not pay any attention to strategies that promise you results in slot play, as it is impossible to guess when a slot will payout, as most reputable games providers manage their slot games with a random number generator (RNG). This ensures that all wins are allocated randomly, without warning or premeditation from any party.

The way you play has no bearing on the machine and cannot manipulate the programming into paying out.


Manage your betting well. You must prepare for a marathon of play on these highly volatile machines, which means that you probably will not be able to play the maximum bet all the time.

The only problem with this is that you generally need to be betting the maximum bet to win the max jackpot on offer. We, therefore, advise you to scale your bet up and down every 50 or so spins. This way, you have a chance of possibly landing the jackpot on a high bet, rather than a low one.

Responsible Bankroll Management

Be strict on yourself. Set a gaming budget and stick to it. If you make some decent wins, separate those wins from your spending budget and be controlled enough not to eat into the wins. Once the spending budget is finished, leave the game to ensure that you can spin another day.
