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. For example, Mega Moolah slot by Microgaming activates Mega Moolah Bonus Game randomly; once this bonus game is activated a player has a chance to hit one of 4 tiered jackpots. 

Some gaming software companies develop other varieties of progressive slots. Thus, PlayTech offers Dollar Ball feature. This is a Lotto Progressive Side game. A player has to pick 5 numbers out of 49. Then after starting the main game, 5 numbers will be drawn randomly. The player hits the Progressive Jackpot if 5 numbers match.

On Marvel slots PlayTech offers 4 linked Progressive jackpots which are also triggered randomly. The Jackpot Game has 4x5 grid with 20 squares under which jackpot signs are, the player clicks on the squares and opens the signs. 3 identical signs hit identical jackpot.

RTG software also offers random jackpots. This jackpot can be won at the end of any game. The denomination, number of coins or paylines do not influence on the chance to win the Progressive Jackpot. However, the larger the bet is, the more chances to win the Jackpot are.

Some software providers such as Microgaming and Playtech allow playing Progressive slots only in the Real Money Mode.
