There are two types of slots, which are fixed jackpot slots and progressive jackpot slots. They are pretty much identical in terms of gameplay, features, and mechanics. The most significant difference is the way payouts happen.
With fixed jackpot slots, there is a hard cap on the amount you can win. For instance, one of the most popular fixed jackpot slots in 2025 is Thunder Crown by Endorphina. Thunder Crown offers a maximum payout of 2,400X, and the maximum stake is set at $100. This means the most you can win is $240,000. If you bet the minimum $0.50, you stand to win a maximum of $1,200. The jackpots are static and relative to the stake amount.
Progressive jackpot slots pay differently. This is because progressive jackpots are always growing. Remember that a portion of each bet goes into the progressive jackpot. The payout depends on how many players have been playing and how much they have wagered. Of course, wide area progressives are bound to grow faster and larger than stand-alone progressives.
There are a few other differences, too. For example, progressive jackpot slots tend to be more volatile. That is to say that they pay less frequently, but those wins are often larger than those on low-volatility slots, which pay less, but more often.
Finally, you must consider that jackpot slots typically offer a lower RTP. That said, our list of top progressive jackpot slot games features a couple of titles with high RTP. It’s important to understand how RTP and volatility affect gameplay. This allows you to determine the risk/reward factor and customize the experience to suit your preferred playing style.
