One of the most attractive types of online slot machines is the progressive slot game. These are the slots that have a progressive jackpot. Progressive slot machines are linked to all the online casinos powered by the same online gambling software. The highest payout is not fixed on Progressive slots as in usual slot games. The amount of the Progressive Jackpot grows every time somebody makes a bet playing at one of the linked online casinos. This means the jackpot continues growing as more people play the slot till someone hits it. Since a percentage of the coins played create the progressive jackpot, the other winning symbols will give you less and sometimes the payback percentage on the progressive slots are less than on other machines in the online casino. As a rule, such jackpots grow very fast and can reach a gigantic amount, take for example Mega Moolah that was more than $6 million.

But not all progressive slots are the same. As a matter of fact, there are 3 types of progressive machines. The individual progressive slots are slots the jackpot of which is based on the players who have bet, lost, thereby contributing to the jackpot money. Another type of slots is the linked progressives. These slots are linked to one another to make up the jackpot. The amount of jackpot on such slots is much bigger than in the individual progressives because more slot games are involved in it. And at last the progressives scattered in a number of online casinos that use the same software. Here you may really hit a life-changing jackpot.

It’s worth mentioning that progressive slot games are available in any online casino only for real money players.
