Progressive Jackpots — plain English
A progressive jackpot is a prize that grows every time someone plays. A small fraction of each bet across many players is added to the pot until one player triggers it. Networked jackpots pool bets from many casinos, which is how they reach millions — but the odds of hitting one are extremely long.
How progressive jackpots work
A slice of every bet feeds the jackpot
Standalone jackpots grow on one machine
Local jackpots pool one casino's players
Networked jackpots pool across many casinos
Jackpots often require a max bet to qualify
The base game usually has a lower RTP
Won at random or via a bonus round
Resets to a seed amount after a win
The trade-off to understand: jackpot slots often have a lower base RTP than standard slots, because part of the return is diverted into the pot. You are effectively paying a little extra for a tiny chance at a huge prize. Treat them as entertainment, never as an income plan.
Famous jackpot networks
Well-known progressive slots include Microgaming's Mega Moolah, NetEnt's Mega Fortune and Playtech's Age of the Gods network. Because these are networked across licensed casinos, the same jackpot can be won at any casino offering the game.

Frequently asked questions
How do progressive jackpots get so big?
A small percentage of every bet from many players — often pooled across multiple licensed casinos on the same game network — is added to the jackpot until someone wins it.
Do jackpot slots have lower RTP?
Often, yes. Part of the return is diverted into the jackpot pool, so the base-game RTP of a progressive slot is frequently lower than a standard slot.
What are the odds of winning a progressive jackpot?
Extremely long — often millions to one. Progressive jackpots should be treated as entertainment, not a realistic way to make money.
