VSO News has listed the best superhero-themed slots on National Superhero Day.

For some it’s our fathers, for others it’s our grandmothers. Either way, we all have a superhero in our lives. For this article, we’ll take you through our favorite superhero-themed online slots.

April 28 is National Superhero Day, so we have you covered for Marvel, DC, and other day-saving characters to enjoy a few game rounds with. You can play them all for free at VegasSlotsOnline.

1 – Thor: Hammer Time by NoLimit City

Go on an adventure with Thor and his hammer on this NoLimit City creation and be in with a chance to win up to 2,328x your stake.

Live the legend with the Thor: Hammer Time online slot. NoLimit City has given the game five reels and three rows that hold 20 fixed paylines. The background music fits the fantasy theme perfectly.

The bet options vary between 0.20 and 100.00, making the slot accessible for both low and high rollers.

There are plenty of features to keep you going, which is typical of NoLimit City games. We’ll start off with the Thor’s Lightning Bonus, which you can only trigger on reel 5. This rewards you with multipliers, sticky wilds, or sticky wild reels. This keeps going until Thor leaves the reels as it nudges itself down and awards respins.

Then there are the Rune Raze and the Hammer Time features, which trigger randomly on any spin. These give you increased chances of landing a prize by transforming symbols.

Finally, the Asgard Spins, which you’ll trigger by collecting Scatter Energy Balls. You’ll see Thor with his multipliers and other modifiers ready to help you achieve those wins.

Don’t just take my word for it. Play the Thor: Hammer Time slot machine and see for yourself.

2 – 4Squad by Red Tiger Gaming

Assemble the 4Sqaud slot machine by launching the six reels and collecting clusters for a chance to win up to 1,279x your stake.

Fight for justice with the 4Squad online slot. Red Tiger Gaming has given this game cluster pays, meaning you’ll win prizes by aligning matching symbols on horizonal or vertical positions. You’ve also got an action-inspired tune to go along with the superhero design of the game.

Collecting superheroes of the same color fills the meters at the top of the grid. Once a meter is full, the corresponding superhero attacks with a feature:

  • Quake (green) removes all low paying symbols from the reels to allow new ones to cascade down.
  • Strike (blue) swaps a random number of positions on the reels for wilds.
  • Burst (red) clones a random symbol on the reels for a number of times.
  • Beam (yellow) awards a multiplier of between 2x and 10x to the win of the triggering spin.

So, what happens when all four are filled during the same spin? You’ll activate Superhero Mode, which is where all low paying symbols are removed and all four superhero features trigger during the same spin.

3 – Wonder Woman Bullets & Bracelets by WMS

The female of the Justice League makes an appearance with the Wonder Woman Bullets & Bracelets online slot. WMS takes you on a superhero adventure with 40 fixed paylines.

Grab your lasso and enjoy a few rounds on the Wonder Woman Bullets & Bracelets online slot, a WMS creation with five reels and three rows.

The higher paying symbols are images of our female superhero in action, which allows you to fully immerse yourself in the game. You’ll be playing with features like Mystery Symbols, which are there to add some extra umph to your gameplay.

Next there’s the U-Spin Wheel feature, which could award you with a monetary prize of up to 10x your bet, a minor, major, or mega jackpot, or a bonus round, which we’ll mention next.

The first of the Wonder Woman Bullets & Bracelets slot bonuses is the Knock Out Wilds Free Games Bonus, which offers you a grid of eight rows high. The more you progress through the free spins, the more rows activate, thus increasing your chances of completing a payline.

Then there’s the Transforming Wilds Free Game Bonus, which throws wilds into random positions on the reels at the end of each spin.

If you want to see what this superhero game in action, then play the Wonder Woman Bullets & Bracelets slot for free.

4 – Cosmic Heroes by Microgaming

Spin through the different galaxies of Microgaming’s Cosmic Heroes online slot. This game gives off a different vibe with crystals and pets taking part in this superhero adventure.

Your basic play includes 243 paylines, which you’ll complete when aligning matching symbols on adjacent reels, starting from the leftmost reel. You’ve then got your standard wilds forming part of the mix. This takes things up a notch doubling every win it forms part of.

Then there’s the spaceship scatter, which takes you to the free spins selection. Choose between four free spins rounds, each of which come with their own set of modifiers like multipliers, Wire Burst multipliers, Rolling Reels, growing multipliers, or the Wild Volcano Feature.

5 – Iron Girl by Play’n GO

Take on a different kind of mission with the Iron Girl slot machine, a Blueprint Gaming creation with 20 fixed paylines and a spatial theme.

Launch into space and discover the cosmic world of the Iron Girl slot machine. This five-reeled game awards instant wins of up to 1,000x your stake. The bet choices range from 0.20 to 100.00, meaning you can try the game out regardless of your budget.

The Iron Girl herself is the wild. She shoots through the grid to substitute for regular symbols to help you achieve those wins.

Every superhero story has a villain, and the Iron Girl online slot has four, which also happen to be the higher paying symbols. When these hit, they lock into place, along with any other villain symbols and wilds present, and award a respin. This feature continues until there are no more new villains or wilds added to the grid.

If that wasn’t enough, you’ve also got the Bounty Bonus, which activates at the end of the respins. Depending on how many respins you achieved, you’ll receive multipliers and sticky villains.

Last but not least, the Iron Armor, which can fly onto the Iron Girl slot reels at any time during your gameplay. This drops up to five wilds in random positions to raise your odds of winning.
