Generally, there are 3 main types of progressive slot machines, standalone, inhouse and wide area.
Standalone progressive slots are not networked. The jackpot is unique to that machine and two standalones side by side can have significantly different jackpots, depending on the amount of play each one receives.
Inhouse slots are networked but only with other slot machines within that casino and all will reflect the same jackpot.
Wide area progressive slots are several unrelated casinos networked together offering the same jackpot.
The slot machines for both inhouse and wide area progressive networks are usually from the same mfg. but the actual slot game can vary.
A land-based casinos usually offers all three types but online casinos generally offer wide area progressive jackpot slots, for example, you can play the same game at any of our recommended Microgaming Casinos and win a progressive jackpot.
For more progressive jackpots for non-USA players, play any of of our recommended CryptoLogic Casinos.
All non-USA players can play all the Microgaming games without restrictions including the progressive slot games. USA players can not play for fun or real.
