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.

Aside from the progressive jackpots, both the Real Time Gaming and CryptoLogic slots offer instant jackpots that can be won at the end of any spin, regardless if the reels stopped on a winning combination or not. The Real Time Gaming casinos accept all players, including USA players from all 50 states while the CryptoLogic casinos only allows players located outside the USA.
