Some of the newest and most popular online casino games right now are Cryptologic Software's unique Marvel Superhero Slots, which can be found at Inter Casino. A series of seven varying types of progressive slot machines - each branded after one of Marvel Comics popular superheroes - Cryptologic's latest batch of games have developed a dedicated following of not just comic book fans, but more so, a following of progressive online jackpot hunter's and slot machine Aficionado's.

This batch of online casino games does indeed create an action-packed virtual experience with excellent payouts and bonuses, not to mention a large variety of coin sizes. Two of the most popular games out of the group, Silver Surfer and Thor, offer nine paylines of betting action and bet sizes as low as five cents per spin. While this a great option for players seeking to change the betting pace and stretch out their bankroll, the payout scale is designed to pay more the more that one bets - and the players tend to go after the larger payout ratio and expansive progressive jackpots.

Thor, for instance, has a bonus round that will pay up to 4,000 times the size of one's bet (even nickel bets) and a Free Games feature that awards up to 12,000 times one's bet. And for the icing on the cake, the three-level progressive jackpots are not only connected between all seven Marvel Superhero slot games (meaning a gambler playing Silver Surfer and a gambler playing Thor both contribute to and vie for the same progressive jackpot), all Cryptologic online casino licensees offering the Marvel games contribute to a single jackpot as well; Hence the three level progressive.

These jackpots are referred to as stand-alone, in-house and wide-area. Money is contributed to the progressive pot from all players on a single Marvel Superhero slot machine (stand-alone), which is then contributed to a pot from all Superhero slots being played at a single online casino (in-house), which is then contributed to a culminating progressive pot networked between multiple online casinos (wide-area). There's no wonder why these jackpots get so large, and why the Marvel Superhero slots are so popular.
