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.
An example
Carribean stud poker is a common game with a progressive jackpot like axie infinity. 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.
How to win
Some games give you the chance to win the progressive jackpot whenever you are playing them. This is often that case with slot machines. Observe that you might have to bet max bet to be able to win the large progressive jackpot.
Other games require you to place a certain side bet to be able to win the jackpot. If you do not place the sidebet then you can not win the jackpot. This is the case when you play earlier mentioned Carribean stud poker.
Exactly how you win the jackpot varies from game to game.

This can include all the casinos in a certain chain of casinos or all casinos that offer a certain game.
