Comic books have become a popular part of modern day culture and one of the leading names in the comic book industry is Marvel Comics that have been created through the genius mind of creator Stan Lee.
Such has been the huge fan following that has developed around these comic books that they have transformed from the being restricted to the cult fan base market into the mainstream with massively successful multi-million dollar movie franchises being released in cinemas across the globe, fully licensed video games being launched on consoles, and merchandise selling worldwide.
Some of the most popular Marvel characters have included Captain America, Iron Man, The Incredible Hulk, Thor, and Spider-Man. They have become household names and icons within their own right with kids and adults alike pretending to be them.
One step of this shift into the mainstream was the licensing agreement signed between casino software developer Playtech and Marvel. It allowed Playtech to develop a range of slots that were inspired by the superheroes created by Lee.
Captain America was the first big hit for Marvel when his first issue comic was released back in 1941. The 5 reel, 20 payline slot covered the bitter rivalry between Steve Rogers and his arch nemesis Red Skull. Its Super Energy Spins made it a hit with slots players as well.
Iron Man took the box office by storm when it was released so there was a great deal of expectation surrounding its release as a slot machine. The slot title did not disappoint. The 5 reel, 25 payline first release had everything an Iron Man fan could wish for. The Missile Attack Bonus gave the potential for up to 20 free spins to be won in a game that also included bomb and rocket symbols.
The first instalment of the Iron Man slots series was so popular with players that Playtech made the decision to develop and release another two slots in the form of the sequels Iron Man 2 and Iron Man 3.
A 5 reel, 25 payline release based on The Incredible Hulk also made major moves in the casinos. Players could win 10 free spins and 3x multipliers in a slot that also gave them the chance to hit Expanding Wilds in one of the more high-octane Playtech releases.
There was also The Avengers slot. That has undoubtedly been the most commercially successful franchise from Marvel with Avengers: Assemble and The Avengers: Age of Ultron and that success was repeated by its debut slot. There is a bonus feature relating to every Avenger where players can win free spins, Extra Wilds, Expanding Wilds, and multipliers.
Another factor that has made the Marvel slots so popular is that they are all linked in to the Marvel progressive jackpot. It has seen players win up to $852,123 with the average win time recorded at 8 weeks between triggers. Marvel slots can be played in Playtech casinos and in casino portals that offer the games for free. The slot machine portal practiceslotmachine.com, for example, offers Iron Man 2, Incredible Hulk and other Marvel free slots.
