Playing online casinos for any amount of potential winnings is enough to get the adrenalin flowing, but when it comes to the possibility of winning the ultimate online jackpots then the excitement becomes paramount.

If going after the big jackpot games is for you ,then you will want to consider these games, keeping in mind however that there are constantly new games being added and the jackpots keep growing. Casino games are categorized according to their platform or software. So although many of the casino games are similar, each platform offers their own types of mega jackpots which average around the same prices. So if you were to find a high playing jackpot in the Playtech platform like Progressive Blackjack, then you would likely find a similar one in the cryptologic platform for example.

Millionaire Genie Slot Machine

One of the favored venues of all is the slot machine, particularly this one. With a progressive jackpot starting at $225,000,000. no one would complain if they won this one before it had the chance to grow.
