What are progressive jackpot slots and how do they work?

A progressive jackpot slot is an online casino game where the jackpot prize is often accumulated across multiple online casinos worldwide. Each time a player bets on a progressive jackpot slot, a small portion of that bet goes directly to the prize pot. This means that a progressive jackpot gets bigger each time the game is played. The prize will continue to increase until one lucky player hits the winning combination. After that, the jackpot resets to a predetermined value and the whole thing starts over again.

For example, in Mega Moolah, players can potentially win one of four progressive jackpots, with the largest starting at a minimum of $1 million. When someone hits that jackpot, they're rewarded with the entire accumulated jackpot amount.

How do payouts work?

Payouts, also known as Return to Player (RTP) percentages, represent the average amount of money that a game returns to players over time. Casino payouts varies between games but generally ranges from 90% to 97%. So, while the odds of hitting the progressive jackpot are slim, the potential payout can be massive, making these casino games a thrilling and potentially rewarding choice for players.

Remember

Thousands of players from around the world can play the same progressive jackpot slot and contribute to the prize pool at the same time. Take a look at our jackpot tracker above and watch the prizes skyrocket right before your eyes.

Different types of progressive jackpot slots

When you play at real money casinos you might come across four different types of progressive jackpots. Each of these types will help determine the size and frequency of the jackpot payout as well as which players contribute to the prize pot.

Progressive jackpot

Each time a player bets on a progressive jackpot slot, a small portion of that bet goes directly to the prize pot. There can also be different games which contribute to the same prize pot, to make the jackpot rise quickly.

Tips to win progressive slot machines

The outcome of a progressive jackpot slot is determined by a RNG (Random Number Generator) so unfortunately, there is no secret strategy that will increase the odds of winning. However, it’s worth keeping an eye on the prize pots for different casino jackpot slots and avoiding those that have been won recently. We’ve also gathered our expert’s top five tips on how to play progressive slots. When you’re ready to play, check out the best jackpot casino online US has to offer.

  • 1
    Stick to a budget: When you play a US progressive jackpot game, the best tip is to decide on a budget before you begin. Then stick to it. You don’t want to risk betting money you don’t have.
  • 2
    Bet enough to be eligible for the jackpot: Some progressive jackpots have a minimum bet to be able to qualify for the jackpot. Make sure you bet enough – but still within your budget – to be eligible.
  • 3
    Decide what you’re going for: The way you bet will change depending on whether you’re playing for one big win or several smaller wins, so decide what type of win you want before you place a bet. Sometimes it might be more lucrative to go for the smaller wins – and win several times.
  • 4
    Do your research: Know which online jackpot game you want to play and how to play it. Find out which jackpot is about to drop and make sure you know the rules of the slot game. You don’t want to spend your cash on a slot machine that just paid out the biggest win.
  • 5
    Determine the volatility of slots: Basically, make sure you understand the risk involved in playing a specific online jackpot game. Volatility is about when you’re expected to win, and how often.

The odds of winning a progressive jackpot

The chance of winning a progressive jackpot depends on which online slot you’re playing. To calculate the odds of winning, you will have to look at how many reels the slot game has and how many symbols are on each reel. You will also need to take into account how the progressive jackpot is triggered.

Keep in mind that all progressive slot games rely on a random number generator, but by calculating these three things, you could get an understanding of the odds of winning the jackpot.

How are progressive jackpots paid?

While many large progressive jackpots are paid in annual instalments, spread out over a decade or more, some prizes including Microgaming’s Mega Moolah jackpot will be paid promptly in one lump sum.

If you happen to win a smaller sum, you can expect your winnings to be credited to your casino account instantly. Yet progressive jackpot winners who secure a record-shattering prize are more likely to be paid by courier, bank transfer, or in person within a matter of days. Don’t be surprised if the online casino asks you to pose with a novelty-sized check.
