Online casinos have many slots nowadays, and one type of slot game that catches the attention of many players is progressive jackpot slots. 

Although the chances of winning the jackpot are slim, you may have wondered what happens if you win. Curious to find out the answer? Read our King Casino blog post below.

What Is a Progressive Jackpot? 

There are various jackpot slots, but a progressive jackpot is interesting as the prize pot increases as people play. 

A progressive jackpot is a prize that continues to increase every time the slot is played, with a portion of each bet placed going towards the pot. The longer the jackpot goes without being won, the higher the prize gets. These slots can be very entertaining, and top prizes can reach up to millions of pounds.

You can also get progressive jackpot systems that have multiple slot games contributing to the same pot, which could result in a faster increase and larger prize.

How To Win The Progressive Jackpot on a Slot Machine 

Every time a player places a bet on a progressive jackpot slot, a small percentage of their bet is added to the jackpot prize pool. Over time, as more players play, a progressive jackpot builds up until it is won. Once the jackpot has been won, the prize amount resets to the base jackpot prize level (seed value), and it begins to increase again.

There isn’t a way to guarantee you win the progressive jackpot on a slot machine since the outcome of a spin is always random. The same is true for triggering a progressive jackpot.

Progressive jackpot prizes typically trigger on a random spin in the course of playing any of the contributing slot games. You can never tell if or when it may happen. It usually involves landing a certain number of a specific bonus symbol, which then takes you to a bonus game for the chance to win the progressive jackpot prize. 

Remember, the outcomes are always random, and nothing is ever guaranteed. Even if you trigger the progressive jackpot bonus round, there’s no guarantee you will win the top prize. 

What Happens When You Win a Progressive Jackpot Online? 

Despite the chances of winning a progressive jackpot online being very small, there is a chance you could win. All players have the same chance of hitting the jackpot, so it could potentially be you.

There are many different ways that a progressive jackpot can potentially be triggered.

If a player wins the progressive jackpot, the jackpot is emptied. The jackpot then resets to the seed amount and starts increasing again.
