A progressive jackpot is a casino jackpot that grows with every bet placed across a network of linked machines or sites until someone wins it. Headline progressive slots like Mega Moolah and Divine Fortune have paid out single jackpots exceeding $20 million.
Also known as: progressive, networked jackpot
Progressive jackpots are funded by a small percentage of every wager on the linked game (typically 1–3%). This funding cuts into base-game RTP — progressive slots usually have lower headline RTP than standard slots from the same studio.
Local progressives are confined to one operator; wide-area progressives span dozens of operators across markets. The biggest jackpots are wide-area.
Hitting the top jackpot is a low-probability event (often 1 in 10–50 million spins). Mid-tier "minor" and "major" jackpots within the same game are far more common and ship the marketing photos.
