Superheroes are everywhere in entertainment media and the world can’t seem to get enough of them. Whether they’re mutants, magic, metahumans, or monsters, they provide entertaining and fantastic stories that keep us glued to our screens. Let’s take a look at some of the best superhero-themed online slots you can discover out there and find out where their power lies.
1. The Dark Knight by Playtech
Christopher Nolan’s brooding film interpretation of the caped crusader is one of the most popular Batman movies ever and Playtech chose to bring its gritty atmosphere to the reels.
Batman, the Joker, and Two-Face make appearances as game symbols on the glowing blue reel set. The Batman symbol can appear stacked and when it does so on the first reel, a coin is flipped, and if it lands on the Batman side, you get a respin, but if the joker side appears, you get nothing. This process repeats up to 8 times as long as you keep getting successful flips. The Joker has his own version of this feature that activates when his symbol appears stacked on reel 5.
Land at least 3 scatters to get to choose from 3 free spins options. You get 7 free spins with extra wilds, boosted symbol values, or jumbo symbols.
Playtech’s progressive jackpot is also included in this game, and as always it is randomly triggered. You win by clicking on a 20-tile grid, revealing colours that correspond to progressive jackpot prizes. Once you have revealed enough of a certain colour, you will be awarded a prize.
2. Wonder Woman by Playtech
Playtech’s 2019 title focuses on the rivalry between the titular Amazonian heroine and the vicious villainess, Cheetah. This progressive slot title has 5 reels, 30 paylines and a spread of bonus features that guarantee a thrilling experience.
A glance at the paytable reveals captivating illustrations of Wonder Woman, Cheetah, and other characters from the comic as high-value symbols. The Wonder Woman logo is the wild symbol, and an image of the hero and villain facing off is the scatter. If the Diana symbol appears fully stacked on the first and fifth reels, the Wonder Woman Re-spins feature activates. The reels will spin again, showing only blank spaces and Diana icons. The appearance of more wonder woman symbols will award you an extra respin, the feature will end when your respins run out or the grid is filled with symbols.
You only need to land two Scatters reels 1 and 5 to get randomly assigned one of 3 free spins games. In Wonder Woman free spins, certain symbols will always appear stacked, in Cheetah free spins, all high-value symbol combinations transform into Cheetah symbols. The Fire Wild free spins version has special Fire Wild symbols that can appear on the second, third and fourth reels. These special symbols will transform one high-value symbol into a Fire Wild for one spin.
Let’s not forget the all-important randomly activated progressive jackpots. The game will transport you to a twenty-tile playing field, where you have to flip tiles that are colour-coded to correspond to one of four jackpots. Keep selecting tiles and you will fill up jackpot meters. The first one to be filled up will pay you out accordingly.
