Progressive slots are slot games with a progressive jackpot, the maximum payout offered by the slot. A progressive jackpot is formed of a small share from each bet played on the particular slot. Players can play the same slot in different online casinos in different parts of the world and a small percentage from every bet adds to the jackpot amount.
That is why the progressive jackpot grows very quickly. The total size of the jackpot is usually displayed above the slot reels. The jackpot grows until someone hits it. Anyway, the odds of hitting the jackpot are small. Most often it is required to wager the maximum number of coins to be eligible for the progressive.
The progressive jackpot can be hit when a certain fixed combination of symbols line up on the reels. There are also jackpots which are triggered randomly.
