The Marvel Superhero slots series is one of the most popular collection of games in the online casino world. Both PlayTech and Cryptologic have designed their own series of games, each of which provides players with an exciting online gambling experience that draws on the adventures of popular comic book characters.

There are dozens of games based on these characters, and – in case you’re spoilt for choice – we’ve decided to narrow them down!

The Incredible Hulk (PlayTech)

The Incredible Hulk is one of the most popular Marvel Superhero slots – and with good reason. Not only does the game offer players engaging gameplay; it also presents great graphics.

From the base game to the bonus rounds, the graphics in the Incredible Hulk online slots are impressive. As comic fans ourselves, we know that graphics are big deal – and this game certainly delivers.

There are not many bonus rounds to choose from (but that is the case with all of the games in the series), but we do enjoy the expanding wilds feature. When it is triggered, the Hulk appears, pulling apart the reels. Only the first and last reels spin, leaving the middle three entirely wild, opening up plenty of winning opportunities.

Captain America (Cryptologic)

Cryptologic’s Marvel Superhero slots are much older than the games that have been designed by PlayTech. So, the graphics are not going to be as impressive. The best-looking game of the bunch is Captain America, which does a great job of emulating comic book art.

Coincidentally, it is also the slots game with the best gameplay. In addition to providing players with a generous set jackpot and three progressive jackpot levels, there are also some great bonus features available.

Players can assume the role of Captain America, throwing his shield at enemies to gain prizes in a fun arcade-style bonus round. There are also some generous on-screen bonuses like wilds and scatters. 

Iron Man (PlayTech)

PlayTech has released two Iron Man slots games. While Iron Man II is the latest game in the series, we’re more partial to the original. While this could be a reflection of our feelings about the move series, we’d also like to think that it has to do with the gameplay. Not only are the graphics impressive; the gameplay is engaging and entertaining.

In the Missile Bonus round, you assume the first-person view as Iron Man himself and shoot missiles at enemies. We really love these kinds of bonuses, because it feels less like you’re playing a slot machine and more like you’re playing an arcade game.

Other great features include a generous free spins round and stacked wilds.
