A progressive jackpot is an amount that is formed based on a certain percentage of the bet. They are different from fixed jackpots - since their size changes with every spin the gambler makes. Typically, a portion of each bet goes to the prize pool, which continues to grow until someone is lucky enough to win it. Once there is a winner, the pool resets to a preset minimum level.

There are several types of progressive jackpots: Standalone, Local, and Global.

Standalone Progressive Jackpots are like solo artists, specific to one machine, be it at a traditional casino or your neighborhood pub. Every bet placed on that particular machine goes towards the jackpot. They might not be life-altering, but can certainly pack a punch with substantial sums.

Then we have Local Progressive Jackpots, the rockstars of online slots. Unlike Standalone, they aren't restricted to one machine but linked to all games within a venue or an online casino. Each bet placed contributes to the growing jackpot until some lucky player strikes it rich. With multiple players participating at once, these prizes can skyrocket in no time.

Finally, we have the big leagues: Global Progressive Jackpots. These aren't just confined to one casino, but span across numerous online venues. Their reach allows them to accumulate incredible sums. They might be elusive, taking months or even years to be claimed, but their life-changing payouts are worth the wait.

So, whether you're playing the lone wolf or chasing colossal sums, there's a progressive jackpot just for you.

The non-progressive jackpot consists of a fixed amount that can be won using a specific combination or in a bonus game. Meanwhile, the progressive one does not have a fixed amount. Thus, every time a gambler plays a particular slot, a certain percentage of the income goes to the general prize pool.

Progressive jackpots keep getting bigger with every bet, racking up hundreds, thousands, or even millions before a lucky player hits the mark. This thrill ride of growing rewards keeps you on your toes, promising potential mega wins.
