Progressive slots have a jackpot that grows by a percentage of each coin played. Oftentimes a number of progressive machines feed into one jackpot where any machine in the group can win, and the jackpot grows into an astronomical amount. These groupings can be a number of machines in one casino, or can be tied to all of the same machines in a whole state. It's very easy to spot progressive slot machines on the casino floor - just look for the bright, neon tickers that display the current jackpot, which is continually increasing as the slots are being played.

Pay attention that progressive slot machines typically entail that you play the maximum number of coins in order to be eligible for the progressive jackpot win. Indisputably, there is perhaps no worse a feeling than hitting a progressive jackpot, only not having played the necessary number of coins.
Because of the great chances of winning a very big jackpot, progressive slots are very popular among slot players. But actually what odds have these progressives?

The odds of being the big winner for one of these progressives are proportional to the size of the jackpot. On small progressive slots there are more wins. On larger progressive slots, there are fewer wins. But someone always ends up winning - eventually. Smaller progressive slots may get jackpot winners as many as four or five times a day and sometimes even more than that. This adds to the allure and excitement surrounding progressives at the Casinos, as so many people play and hope that they get to pose beside a big fat check for millions on the winners' wall.
