Everything you need to know about jackpots in an online casino: are they completely random or predetermined?

Jackpots are one of the most exciting parts of online casinos. The idea that you could win a huge prize at any moment makes the thrill unparalleled. But one question that often comes up is: are jackpots completely random, or are they predetermined?

Both possibilities exist, depending on the type of game, the type of jackpot and the game provider. Let's take a look at this step by step.

PepperMill Jackpots: completely random with a twist

At PepperMill Casino, we have our own PepperMill Jackpots, where you have the chance to win 3 different types of jackpots. Winning one of these jackpots is completely random: every spin could make you the lucky winner.

First, there is the biggest jackpot, the Random Drop. This continues to grow with every bet and can be won at any time. The other two jackpots have a few extra elements built in. The Mill Drop is completely random, but always before the amount reaches €1,000. In addition, the Chrono Drop always falls before 3 hours have passed. When you win a PepperMill Jackpot, you will see a pop-up indicating that you have won. You then have to spin the wheel to see which jackpot you have won.

In-game jackpots

Many providers also build their own jackpot mechanisms into the games. This is where you see an important distinction between jackpot games and jackpots that are awarded immediately after spinning.

Instant jackpots

Most jackpots are awarded immediately after you press the SPIN button and the animations start. With Hold & Win slots, you can collect jackpots during a respin feature. You will see that you have won a jackpot, and the amount will be added to your balance immediately.

Of course, the outcome is completely random and is only determined by the RNG after you have pressed spin.

Jackpot games

Some jackpots can only be won in the jackpot game, which you must first unlock. This is the case with the popular games from Amusnet, among others. Here, you choose a card yourself and thus determine which jackpot you will receive (Mini, Minor, Major or Grand). In these games, too, the outcome is entirely based on luck, but the final outcome is only determined when you make your choice.

How do jackpots work?

Jackpots are controlled by a Random Number Generator (RNG). This system randomly determines the outcomes of spins, bonuses and jackpots. Providers and casinos cannot influence who wins these or when they will be won. There are different types of jackpots:

  • Fixed jackpots – a fixed amount that you can win (for example, €1,000).

    • Progressive jackpots – an ever-increasing pot that grows with every bet placed by players.

      • Must-drop jackpots – guaranteed to drop within a certain time or for a certain amount (such as our Mill and Chrono drops).

        The most important thing to know is that jackpots always drop randomly and there is no way to predict or force them. You can win PepperMill jackpots by placing a bet on any game, with any stake.

        In addition, you can also win a jackpot in the games themselves. In some games, you will immediately discover that you have won a jackpot and how much it is worth. Other games add an extra game element or require you to unlock a bonus round before you have a chance to win a jackpot.
