What Are Jackpot Slots?

What are jackpot slots? Now, that’s a good question. Typically, these are slot games that offer significantly larger win potential. When it comes to jackpot slot games UK, we’ve got two primary categories: progressive jackpots, and fixed or non-progressive slots. The latter offer a fixed max win, while progressive jackpots will grow over time, financed by real-money bets from players playing across the operator network around the world – until someone finally lands the final, life-altering prize and the jackpot resets to its original value.

Types of Jackpot Slots You Can Play

One of the main characteristics of progressive jackpot slots is that they include potentially enormous wins, however within this game genre we find a variety of formats that are suited to different player types. Here are some of the most popular. 

Fixed Jackpot Slots

Fixed or non-progressive jackpot slots include a fixed maximum prize that doesn’t change. A great example would be Fruit Fiesta by Microgaming which offers a fixed £10,000 jackpot prize. Winning these jackpots generally includes landing specific symbol combinations with the prize resetting to the same value each time. While rewards on these jackpots tend to be smaller, this game type is still sought out for its entertaining and highly volatile gameplay.

Progressive Jackpot Slots

The main difference with progressive jackpot slots is that for every real-money spin happening across a network of players, the jackpot pool prize continues to grow until it’s finally claimed. These casino jackpot slots have been known to repeatedly delivering the biggest jackpot wins of all time.

Must Drop Jackpot Slots

This jackpot slot variation includes a fixed time limit that determines by when the jackpot needs to be won. These types of casino jackpots may include daily, hourly, or even weekly expiry dates. Great examples of this would include Cash Quest or Dragon’s Luck Power Reels, both by Red Tiger Gaming.

Local (In-House) Jackpots

This online jackpot slots variant is usually found exclusively at a single casino or online brand and does not form part of the larger operator networks, which is what makes them different from progressive jackpots. In this case, only players at that specific casino are able to participate, with prizes generally being smaller, yet the odds of winning comparatively higher.

Network Jackpots

And lastly, network jackpots are those shared across multiple casinos which in turn cause the prize pools to increase at a faster rate. These progressive jackpots are available to players participating from different casinos on the network with popular titles including Mega Fortune by NetEnt and Age of the Gods by Playtech.

How Progressive Jackpots Work at Online Casinos

Progressive jackpot slots grow in value with every real-money bet placed by participating players. Each spin contributes a small percentage to the jackpot prize pool, which continues to increase until one unsuspecting (and very lucky!) player lands the winning spin. These types of jackpot slots can either be local or networked.

• Network jackpots – these include several casinos linking up to the game developer’s network, with contributions coming in from players worldwide. These casino jackpots tend to grow at a much faster rate and lead to considerably larger prizes.
• Local jackpots – this type of progressive jackpot slot is exclusive to a single casino or brand and will grow when funded by players trying to win a progressive jackpot at the same casino. These prizes tend to be more modest yet statistically more achievable.

Jackpot Slot RTP & Payout Frequency

If you play progressive slots, then you’re already aware that the typical RTP (return to player) is usually more conservative when compared to video slots, and this is to compensate for the massive win potential these games include. It’s also impossible to determine at which point in the game journey this payout will drop – but if it ever does, you’re going to want to make sure you’re playing the best progressive jackpot slots at the best UK payout casinos of course.

Daily jackpots, on the other hand, are guaranteed to drop by the stroke of midnight each day, making them a more predictable option while still retaining the high-energy gameplay we associate with this game genre.

And lastly, fixed jackpots offer frequent, smaller wins during the base game, as their jackpots are set and will not fluctuate or increase in size over time. This type of non progressive jackpot slot tends to have a higher RTP and statistically offers better odds of winning a jackpot, but with considerably smaller rewards.

When picking the right online jackpot for you, keep the balance of RTP and jackpot potential in mind. While playing progressive slots could result in unimaginable win potential, the odds of winning a fixed jackpot are infinitely larger despite their jackpots being substantially smaller in size.
