What are Online Jackpot Slots?

Online jackpot slots are online slot games that have the potential to pay out huge cash prizes. When playing these games, a small fraction of each real money wager goes into the progressive jackpot. The jackpot is re-seeded at its original value whenever it’s won and begins to grow again.

The following list features the top jackpot slots that you can find at online casinos in Europe.

Mega Moolah – Microgaming

Mega Moolah, released by Microgaming in 2006, is one of the top progressive jackpot slots online. Symbols in the game reflect an African safari setting and feature animals, including lions, elephants, and zebras. If the player gets three scatter symbols in any position on the reels, they will enter the jackpot bonus round.

The bonus game involves spinning a Mega Moolah Jackpot wheel for a chance to win one of four jackpots.

Mega Moolah Isis Jackpot Slot

Mega Moolah Isis – Microgaming

Yet another Microgaming progressive jackpot slot. This time around, pyramids, scarab beetles, hawks (scatter symbols), and the Eye of Horus are some of the Egyptian icons that make an appearance at this slot. The Mega Moolah Jackpot Bonus game can trigger randomly, giving players a chance to win one of four progressive jackpots: the Mini, Minor, Major, or Mega.

The Isis version of Mega Moolah comes with 15 free spins, multipliers, scatter symbols, and a gambling feature.

Like most jackpot slots, this game has 20 paylines that pay out when players get a winning combination. Hammers, shields, ravens, and gods (Thor, Loki, Odin, Freya, Idun) are all present and accounted for.

Players who get three Bonus symbols can play the Jackpot game and try their luck at winning a Mini, Major, or Mega Jackpot.

Popular Types of Online Jackpot Slots

The jackpot slots available at European online casinos come in a few varieties, each with its own mechanism for amassing a jackpot. The most common types are the following.

Local Jackpots

These jackpots are specific to one casino or group of casinos owned by the same online gambling company, like Greentube, White Hat Gaming or Dama N.V, for example. A portion of every wager made on the game goes into the jackpot prize pool, which continues to grow until won. Once the jackpot is hit, it’s reset to its seed value and starts growing again.

Progressive Jackpots

Progressive jackpots are like local jackpots in that a portion of each wager goes into the prize pool. When a jackpot is won, the prize money is returned to its original starting point, and the process begins again.

However, progressive jackpots are not limited to a single online gambling establishment or group of casinos.

Instead, the funds are pooled across multiple online casinos around the world, with the total prize pool increasing as more people play.

Network Jackpots

Network or pooled jackpots are the same as progressive jackpots in that they are pooled across a network of casinos, and the prize pot grows larger as more people play. The difference is that network progressive jackpots tend to be much larger than the classic type of progressives, as they are usually fed by multiple online casino brands.

When the jackpot is won, it is reset to its seed value and starts growing again.

Fixed Jackpots

Fixed jackpots are just what they sound like; the prize pool is fixed at a certain amount. This means that the jackpot will never grow any larger, no matter how many people play. However, it also means that the odds of winning are usually better than with other types of jackpots.

Seasonal Jackpots

Seasonal jackpots are those that are only available during certain times of the year. It’s possible, for instance, to come across a daily jackpot that’s only up for winning for the month during the Christmas season. Similarly, you might find a weekly jackpot that is only available to be won during the summer months.

Mystery Jackpots

Mystery jackpots are prizes of varying amounts that are not attached to any specific game. Instead, they are available for random winning by any casino player while wagering real money. These jackpots typically have smaller top prizes than others.

How Jackpot Slots Compare to Regular Online Slots

Now that we’ve looked at some of the most popular jackpot slots and types, let’s answer the burning question: are these games really better than regular online slots played in Europe?

The answer largely depends on personal taste in casino games. If you want a real shot at winning a fortune, play progressive jackpot slots. These games might make you a millionaire instantly if you’re lucky.

On the other hand, if you just want a little fun and the chance to win a few euros, standard online casino slot games may be more your speed. The top wins in these games are generally smaller, but you have higher odds of winning, so you can often come out ahead over time.

In the end, you decide what kind of game to play. If you’re in the mood, try your luck at a progressive slot machine.
