What Are Online Casino Jackpot Games?

All slot games offer you a prize: You get a payout for landing the same symbols next to each other. However, some slot games also offer a big prize for landing specific symbols or just for being lucky enough: These big prizes are called “jackpots”. A jackpot can be big enough to make you a millionaire, and casino games that offer this feature are called “online casino jackpots”.

Types of Online Casino Jackpots

There are two kinds of online casino jackpots: fixed and progressive. Cash Coaster and Piggy Riches slots are examples of fixed jackpot games. For example, Piggy Riches has a maximum payout of 360.000 coins. This is a big amount but it is “fixed”: Which means it never changes. Progressive jackpots, on the other hand, do not have a fixed prize. Their big payouts keep increasing with every game played and sometimes reach millions. However, they also offer lower RTP values. In short, fixed jackpots pay less but they are easier to win. Progressive jackpots pay very big but harder to win.

Let’s continue with a list of all jackpots online casino winners. These players tried their chances at many websites (such as online casino Jackpot City) and played progressive jackpot games. Some of them were luckier than others: This is the list of the biggest jackpot winners.

What Is Your Chance Of An Online Casino Jackpot Win?

Further Information

The truth is, nobody knows: The result of each spin is calculated by a random number generator (RNG) so any player can win at any time – only the online casino software knows! The RTP rates of online casino jackpots show how much of your investment can be recovered in the long run, they are not related to winning chance. For example, if the RTP rate is 95% and you spent 100 EUR/USD, you can recover 95 EUR/USD if you play long enough.

ow to Win Online Casino Jackpots?

The results of online casino games are determined by RNG software, as mentioned above. So there is no “guaranteed” way of winning online casino jackpots. However, we can list some tips that can help you:

  1. In order to find the biggest jackpots, use an online casino jackpot tracker. These trackers show a list of all current jackpots and their prize amounts.
  2. Check the RTP values. Online casino jackpots usually have lower RTP percentages when compared to other slots. However, you should still prefer jackpots that offer an RTP of 85% and higher. Also, always read the paytable and find out how you can win the jackpot.
  3. Make sure to have a big bankroll: Winning online casino jackpots will require more play time and cost more. For the same reason, pick a payment casino method that suits you best: We recommend checking out RoyalPay casino and Kluwp casino payments.
  4. Remember that slot machines are not your only options: There are other casino games (i.e. high limit blackjack, European blackjack) that offer a big payout.
  5. Make sure to use a bonus (i.e. casino cashback bonus) in order to maximize your bankroll. You can compare online casinos on our website to find the best bonuses.

Should You Play Online Casino Jackpot Slots?

Online casino jackpots are fun and they can really make you a millionaire: That’s their obvious benefit. However, they are also harder to win when compared to regular slot games. You can win a fortune, that’s for sure, but you can also spend a fortune if you are not careful. For this reason, make sure that you have a big bankroll to cover your losses until you score a win: If you are on a limited budget, online casino jackpots may not be the best option for you.
