What Are Progressive Slots

Progressive slot machines work in much the same way as any other slot games. The basic gameplay remains the same. You set your wager, spin the reels, and win payouts for lining up winning symbol combinations. What sets progressive slots apart from other slots is the big jackpot prizes that they offer.

When you play progressive online slots, with real money or a slots deposit bonus, a small portion of all wagers is added to the jackpot prize pool. Many jackpot slots are linked, with jackpot prize pools shared across various casino games at multiple online gambling companies. As such, these jackpots can offer huge prizes in the millions. Progressive slot games usually feature a lower RTP, yet the big jackpots compensate for this.

How to Play – What Happens When You Win?

Playing progressive slot machines online works in a similar way to playing any other online slot game. You do not need to learn any special rules to play. Simply select your game and spin the reels. Still, there are a few things that you need to keep in mind. Your bet size is a key consideration. You should always check if you need to play with a certain wager to be eligible to win the jackpot. Here is a simple guide on how to play progressive jackpot slots online:

There you have it, the simple rules you need to know to play an progressive slot machine game. In short, there is little difference in how to play online slots and how to play jackpot slots. If you are lucky enough to win a progressive jackpot, you can expect a jubilant onscreen display celebrating your win.

Your jackpot prize will be reflected in your casino account balance. However, jackpot wins could be collected differently to standard game prizes. You can expect the casino will be quick to contact you and congratulate you on your win. They will also explain how your prize will be paid.

Given the huge amounts of cash involved in a jackpot win, most casinos prefer to pay your winnings directly to your bank account. Yet the process can vary depending on the operator and the jackpot network. For example, Microgaming has strict rules in place that require online casinos to pay a jackpot prize in full and promptly. On the other hand, IGT progressive jackpot slots pay jackpots in an annuity over a period of time.

What Are the Odds – RTP & Payouts in Progressive Slots

When you play slots online, you can tell how well the game pays out by checking the RTP. The return to player rate expresses the percentage of all wagers on a game paid back to players as winnings over the long run. The higher the payout percentage, the more the game pays out.

Progressive online slots generally feature a lower RTP than regular slots. This is because a portion of bets goes into the jackpot pool. You could find that some jackpot slots have a base payout percentage, which increases as the size of the jackpot builds. The odds of winning do not increase as the RTP increases. However, the overall percentage paid out on the slot does. Here are the key details of some of the top-rated online progressive slots:

You are unlikely to find progressive slot machine games among the highest RTP slots online. Still, the chance to win significant sums of money makes them among the most popular types of online slots for UK players. Jackpots can be triggered in different ways. Many are randomly awarded after any spin. Some are won with a certain symbol combination. And others come through pick and win or spin the wheel bonus rounds. Either way, an RNG ensures that progressive jackpot slots are fair and in no way fixed.

Before you play a progressive slot machine, you should check the game rules in the paytable. Some games require a minimum wager to be eligible to win the jackpot. For instance, Jackpot Giant must be played with max bet to qualify for the pooled jackpot. With many other progressives, the chance to win the jackpot increases with the bet size. So, checking the rules and betting limits can help you select the best casino games to match your bankroll.

Differences Between Land-Based and Online Jackpot Slots

You can play progressive slot machines in land-based casinos as well as online. In this guide, we have focused mainly on online progressive slots. Online casino slots feature various advantages. For starters, you can conveniently play for your shot at winning big money. Forget costly trips to Las Vegas, when you could play from home or out and about on your mobile. Check out the highlights of playing jackpot slots online:

Advantages:

• Hundreds of Games
• Jackpots Build Quickly
• Play with Casino Bonuses
• High Payout Percentages
• Convenient and Safe
• Mobile-Friendly Games

Disadvantages:

• Lack of Atmosphere
• Payouts are Not Instant

For all the pros of online jackpot slots, progressive land-based slots also have their advantages. The world’s first wide area progressive jackpot system, Megabucks, is one of the most popular networks. You could play slots in Las Vegas, Nevada and Atlantic City, New Jersey with pooled prizes that reach staggering heights.

While online progressive slots can provide huge progressive jackpots, they fall short of those available in land-based casinos. IGT’s Megabucks has paid out more than $1 billion since its inception in 1986. When the jackpot is won, it resets to a cool $10 million. It also holds the record for the biggest ever slot jackpot payout of $39.7 million, which was won at Excalibur Casino, Las Vegas in 2003.

Types of Online Slot Jackpots

Differences can be found between the types of jackpots available in online slots. Not all jackpot slots are progressive. You could play games with a fixed jackpot prize that does not change. Progressive slots come in various forms also. Some feature multiple jackpots of different sizes. The jackpot sizes could vary depending on how many games are linked to a jackpot, plus how many players bet on then.

Some games feature exclusive jackpots, whereas other jackpots are pooled between various games. The biggest jackpots are those with pooled jackpots linking various games at multiple online casinos. Thanks to the big prizes on offer, these are also the most popular types of jackpot slots online. In the following sections, we will delve into the main types of slot jackpots in more detail.

Stand-Alone Slot Jackpots

Local (In-House) Slot Jackpots

Wide Area Network Slot Jackpots

You could play popular pooled jackpot slots at many online casinos. And you could win the jackpot playing at any of the online casinos within the network. Some pooled jackpots also link different game titles. For example, all of Playtech’s Age of the Gods slot variants share the same jackpot prize pool. Of course, you can play the best pooled progressive jackpots in the UK at the top progressive slots sites.

Fixed (Non-Progressive) Slot Jackpots

Must Drop Slot Jackpots

Progressive Slots with Multiple Jackpots
