Progressive Jackpot

A progressive jackpot is a prize pool that grows every time somebody spins a linked slot without winning it. A tiny slice of each bet feeds the pot, and the counter keeps climbing until one player hits the trigger and takes the whole thing.

There are two flavors. Standalone progressives live on a single game at a single casino, so the pool stays modest (five-figure territory, usually). Networked progressives link thousands of machines across many operators, which is how names like Mega Moolah hit 10 million and beyond. Microgaming's network has made more than one overnight millionaire. That's not marketing; the payouts are public record.

The trade-off is math. Base-game RTP on progressive slots usually sits lower than on flat-prize equivalents, because the jackpot contribution has to come from somewhere. You're buying a lottery ticket layered on top of a slot. Fine if you understand the deal going in. A problem if you assume the base game plays like any other 96% RTP title, because it doesn't.
