Playing jackpot slots online is entertaining and can provide players with an opportunity to win life-changing prizes. Here we discuss what progressive slots are and the different types as well as listing some of the best games and where they can be played for free.

What is a Progressive Slot Machine?

Progressive slots are a popular type of casino game of which there are two basic types. The first type has what is known as a progressive jackpot. What this means is that the jackpot grows every time that the game is played. A small portion of each bet placed goes into the jackpot so that it continually grows until somebody wins it at which time the pot resets to an initial amount. As the pot size is always changing the chances are that no two players will win a jackpot of exactly the same size. The second type of progressive slot works in a slightly different way. The jackpots are of a fixed amount. They are called progressive slots because the player has to work their way through a series of stages in a game, with each stage rewarding the player with a progressively larger jackpot. Any two players who win the jackpot will receive the same amount as it is fixed at each stage. Both types of progressive slots can be very rewarding. The largest overall payouts are from some of the slots with progressive jackpots but progressives with fixed pots will generally hit more often.

Progressive Jackpot Slots

Progressive jackpot slots have the most impressive payouts of any online casino game. Some jackpots can reach millions of dollars in size but others don’t get anywhere near that large. There are 2 different types of progressive jackpot slots:

Local Progressive Slots:These are slots where any bet made by a player on that particular game in the same casino goes into the jackpot. Jackpot sizes can be in the tens of thousands of dollars so are pretty impressive. They are known as local progressives because only bets made by players in the same casino contribute to the jackpot.

Network Progressive Jackpot Slots:This type of progressive jackpot slot includes the games that really grab player’s attention. They are the ones that produce multi-million dollar jackpots. The slot game is networked through multiple online casinos so jackpots grow much faster as well as much larger. The largest ever network progressive jackpot won was over €18 million or 26 million Canadian dollars on the Mega Moolah slot from Microgaming.

One thing to keep in mind when playing progressive jackpot slots is that you usually have to play the maximum amount of coins in order to qualify for the biggest jackpot which isn’t always feasible if you have a limited budget.
