How they work
Progressive jackpots increase whenever a player places a wager, and these games often have a seed level funded by the casino or slot developer. This is the starting point for the jackpot.
For example, if the Mega Moolah progressive slot from Microgaming has a seed value of $1 million, and a player hits the jackpot, the seed value will reset to $1 million.
These are usually networked, meaning you can find them on multiple games and casinos. This can ultimately increase the payout, because more players can access the jackpot. It also means you should play the game more often, because the chance of winning the pot is higher.
