What are Jackpot Slots?

The first slot machine to feature progressive jackpots was Mega Moolah, created by Microgaming.  Jackpot slots feature a unique prize pot(s) that is increased each time a player wagers on the game. Some of these jackpots, known as networked progressive jackpots, aggregate over several casinos and aren't only available on the specific website they're on.

This results in enormous jackpots that a lucky player could win at random. There are situations where players must wager a specific amount in order to be eligible to win the jackpot, but each game will have a different rule. Smaller jackpots are typically easier to trigger than larger ones, and several jackpot kinds are typically found within a single game.

How do Jackpot Slots work?

A portion of each wager made on a slot machine with a progressive jackpot is added to the pot, which keeps rising until a very fortunate player wins it. This causes the jackpot to reset to a seed amount and restarts the entire process. The total, also known as the metre, can rise to enormous sums due to the thousands of players from various slots throughout the globe that can contribute to it.

A large number of progressive jackpots are connected to multiple online casinos, increasing the number of players that can contribute to the prize. The prize becomes larger and offers the chance to win millions of pounds the longer it remains unclaimed. A progressive jackpot that is connected to only one casino is known as a local jackpot. 

Some progressive jackpot slots use a developer-wide system such as the Jackpot King system from Blueprint Gaming. Many progressive jackpot slot systems will have multiple prize pots, with the fewer pots capped at specific values, and the highest pot having no cap on its potential value. In some jackpot systems prizes must be won within a certain period, meaning, for example, someone will win the jackpot prize within a 7-day period. Other pots will simply grow and grow for as long as it takes for one lucky player to beat the odds.

Popular Jackpot Slots To Try

Jackpot slots are very popular with online slot fans, and many of the most popular traditional slot franchises will release a jackpot variant of their game for players to enjoy. At Prime Slots you’ll find a large selection of the best-loved jackpot slots, such as the games featured below:

The jackpot system which these games use is called the Mega Jackpot system. These are three randomly triggered Progressive Jackpots. Any spin has the potential to award the Mini, Midi, or Maxi progressive jackpots at random. After it is won, the jackpot reverts to its initial seeding value. Fluffy Favourites games which use this system include Fluffy Favourites Fairground Mega Jackpot, Fluffy Favourites Mega Jackpot, and Fluffy Too Mega Jackpot.

Jackpot Slots Vs. Traditional Slots

Jackpot slots are a distinct sub-category of online slots. Jackpot slots aren’t better than regular slots or vice versa and instead are designed to appeal to different types of players looking for specific slot experiences. The table below compares and contrasts jackpot slots and regular slots.

CriteriaJackpot SlotsRegular Slots
Payout StructureJackpot slots will have a top prize for the respective slot, but will also be linked to a progressive prize network, with the high-value prize pot continually increasing as players spin the reels of slots in the network.Regular slots will have a fixed jackpot, which is the highest-paying symbol combination. Wild symbols, for example, are often the highest-paying symbols for regular slots.
Potential Payout SizeMany jackpot slots have multiple pots, with smaller and medium-value pots reaching a cap value and then resetting to their seed value when the prize is won. The grand jackpot, however, will have no cap and can reach into the millions in value.The top prizes for regular slot machines can fluctuate broadly. Some slots have relatively low prizes of around 500x the player's total bet, while others will have prizes of 10,000x or even greater.
Winning ChancesAs most progressive jackpot games share their progressive pot with multiple other slot games across the network, your odds of winning the jackpot are very slim. However, it is this ‘what if’ potential which many players find exciting about jackpot slots.The odds of winning the grand prize of a regular slot are also low and rely on a lot of luck. Some slots have more generous odds than others, which is why paying attention to factors like return to player and hit rates is important.
The Stakes & BankrollAs part of your wager contributes to the progressive prize pot, jackpot slot machines tend to have a higher minimum betting requirement.Regular slots can be spun for as little as a penny, with the most common minimum value with all lines covered being around 10p.
