Progressive slot machines are attractive to players because they offer jackpots that are larger than usual and in some cases these jackpots are large enough to change your life.
Progressive machines are a group of slot machines linked together by a network, the big progressive jackpot is made by taking a percentage of all the money played into these machines. This means that the jackpot continues to grow as more people play the machine until someone hits the winning symbols to claim the jackpot.
“Megabucks” or “Quarter Mania” are examples of machines from several casinos linked together to offer a life changing jackpot. Keep in mind that the percentage of the payback on the lesser wins is lowered to allow for the big prize. Some casinos have machines linked together within their own casino to offer mini-progressive jackpots.
A precentage of the coins played form the progressive jackpot, this means the actual payback percentage will be less on the other winning symbols and in some cases the payback percentage on the progressive machines will be less than other machines in the casino. This is true for the machines that offer the life changing jackpots.
If you play less than the maximum coins required, you contribute to the progressive jackpot without having a chance of ever winning it. That's why, when playing progressives, never bet less than the maximum credits required to qualify for the jackpot.
