Progressive Slot Machines are a modern variation of the classic Slot Machines where an attractive progressive jackpot is offered to the winner. These progressive Slots are often linked together in a way that allows a group of machines to grant a particularly large prize, or jackpot. Each Slot Machine in the group contributes a small amount to this progressive jackpot, that is then awarded to the lucky player who hits it.

For instance, a specific combination of symbols on a regular 3 reel or 5 reel Slot Machine pays a certain amount of money. But the amount paid for a progressive jackpot in progressive Slots is far higher than any amount a single Slot Machine could pay on its own.

Progressive Slots Machines offer the highest jackpots of any Slot Machines games, because every player playing in one of the linked machines helps increase the jackpot. Some of these progressive jackpot Slot games are even available in machines linked at more than one Casino, meaning that the number of people that will be playing the same game at the same time will be much higher. Sometimes even a series of different Slot Machines games contribute and qualify for the same progressive jackpot.

Other main Slot Machines types are the classic 3 reel Slot Machines and the multi-line Slot Machines
