Progressive Jackpot Slots
You might have heard about progressive jackpot slots, or seen the games with running jackpots already, but do you also know how the different jackpots work? There are two types of jackpot games, those with a local jackpot and those with a pooled jackpot. What they are and how they work is explained here. You can also find the best jackpot slots and try them for free.
What is a progressive jackpot?
A slot machine with a jackpot is a game that offers a larger jackpot that grows as the players play the game. Each spin a portion of the stake is taken and added to the jackpot. The progressive jackpot slots usually offer a higher jackpot than games that are non-progressive, but they can also be much harder to win. These games are usually of higher variance, meaning they have a higher risk and players might not win much during game-play, unless a special feature or jackpot is triggered.
Do I have to play the maximum bet to get the chance to win the jackpot?
That really depends on the game, but with most online games you won't have to play the maximum bet. However, there are a few games that have a higher chance of you winning the jackpot if you play with a higher stake. There are also some games that adjust the jackpot size in proportion to the bet size. You can find information of how the jackpot is won in the game rules of the jackpot game. One thing to keep in mind is that these are high risk games, and you shouldn't play it if you can't afford to lose the money.
Slots with a local jackpot
Most slots that you can find in the casinos have a local jackpot. This means that the jackpot is fed by bets from players that play in the casino, and only them. The slot has a different sized jackpot in every casino that offers that particular game. This jackpot is usually much lower than that of a pooled jackpot, as it is only the players from one casino contributing to the size.
Slots with a pooled network jackpot
A pooled jackpot is fed by bets from players of every casino that offers that particular game. This means that it's not just players from one casino, but from many. These jackpots can be much larger in size - often many million euros - and their value is the same across the casinos. Some examples of pooled jackpots are Gladiator from Playtech, Mega Fortune from NetEnt and Mega Moolah from Microgaming.
Jackpot reset values
When a player wins a jackpot it doesn't go back to zero. Each game has a starting jackpot, but it depends on the type of game how high the starting value is. It is generally much higher with a pooled jackpot, often around 500,000 or 1 million euros.
Free play online slots with progressive jackpots
You can find many free play online sots on the Internet and in the casinos. But as it is with free games on the internet - you can't win any real money. But you can try the game, see how it works and if you like it. Depending on your country of residence you may have to register to play the free games at the casino, and in some cases you will also have to verify your age and identity with the provider.
