Progressive jackpots are jackpots that keep growing until someone wins them. Whenever someone wins the jackpot it is reset to its starting value and will start growing again until some one wins it again. The largest win available in most casinos is a progressive jackpot. The odds of winning these jackpots are often very small which allows them to grow very large before someone wins them.
Carribean stud poker is a common game with a progressive jackpot. The odds of receiving a Royal flush and winning the jackpot is a mere 1 in 649,740. If it cost USD1 to play the bonus game and get the chance to win the progressive jackpot then we would expect the jackpot to grow to at least USD 649,740 before someone wins it. A royal flush will hower not appear once in 649,740 hands. A royal flush might appear 3 times in a 100 hands and then not appear again for another 10 000 000 hands. 1 in 649,740 is merely the average frequency of royal flush over billions of hands. This often allows the jackpot to grow a lot larger than USD 649,740 and it can often be worth several millions. Slot machines might have progressive jackpots worth tens of millions.
