A networked jackpot is a progressive jackpot linked across many casinos. Every qualifying stake on the game, at every participating site, adds to one shared pot, and a player at any of them can win it.
Pooling contributions from a large player base is what lets these jackpots reach very large amounts. The jackpot is run by the game provider, which holds the pool and pays the winner through the casino where they played. Examples include the Mega Moolah network from Games Global and similar systems from other large studios.
Because so many people are playing for the same pot, the chance of any one spin winning it is extremely small. The jackpot contribution is taken from every spin, so the base game's RTP is lower than it would otherwise be. See our progressive jackpots feature page.
