Online casinos made great strides in terms of gaming entertainment a few years back with the debut of progressive jackpot games. Chances are, you are already familiar with them, but if not, they are basically set up so that every time a player bets, part of the wager goes into the progressive pool which is inter-connected amongst many other participating casinos. This allows jackpots to build very rapidly, and to reach astonomical levels. When the right combination appears, a player claims the jackpot, and then the game restarts from its predetermined level.

Microgaming is undoubtedly the leader in online progressives, as they have biggest variety while producing the highest win totals as well as number of winners. The record so far for a single jackpot win stands at a little over 1.7 million.
