Review of Justice League Slots

I grew up loving the original cartoon starring the “Super Friends” of the Justice League so I was very excited when I heard that NextGen was releasing this online slot game. Sadly, it doesn’t remind me of those classic shows in any way because this game is based on the modern Justice League, and although I’ve watched a bunch of episodes I definitely prefer the original.

I was also surprised when I started to write this review of Justice League Slots to see that they dropped the “America” from the title of their organization. Growing up it was always the “Justice League of America”, but the cartoons in the early 2000s rebranded, perhaps in an attempt to reach a more global audience. In any event, the team is still comprised of some of the best superheroes that DC Comics has to offer, and thankfully they chose to use the real Aquaman and not the terrible 1990s version.

Even though I was disappointed to find out that this game was based on the reboot, I was still excited to give it a try. Unfortunately, I don’t think that it was as good as it could have been, especially when you consider that it features seven superheroes.


There is a ton of action in this game as you can see from the screenshots below, with superheroes soaring, symbols flashing, and power meters getting pumped up. There always seems to be something flying onto the screen or buzzing around in the background so there is certainly a lot to look at.


The only thing better than one superhero saving the day is an entire league of superheroes joining together to battle evil throughout the universe and protect Mankind from destruction. This time it’s the evil Darkseid who’s come to terrorize Metropolis along with his evil Parademons, and the Justice League is the only thing that can stop them. As a result, Batman, Superman, Aquaman, Flash, Green Lantern, Cyborg, and Wonder Woman have all joined together to defend the city and save the day.

Unfortunately, due to the fact that there aren’t proper bonus rounds or an abundance of reel features, we never get to dive into any semblance of a storyline: it’s simply a lot of spinning reels with superheroes flying all over the screen. Sure this is great for a while, but the game’s creators could have easily included some cool battle rounds or something to keep players interested.

Older fans may also be disappointed that Justice League Slots is based on the newer graphic novels that have been released since 2011 and the animated series from the early 2000s. I’m pretty sure that I’m not the only one who’s waiting for a game based on the original show from the 1960s to be released.

Unique Symbols

You should find most of your favorites here, but pickier fans may argue that more of the Justice League members should have been included. Of course it would have been amazing to see niche characters like Hawkman, Shazam, Green Arrow, Atom, or Black Canary be included in the game, but I think we all know that NextGen wanted to play it safe and appeal to a wide audience by only featuring DC’s most popular superheroes. In fairness, due to the style of the animations the reels look pretty full as it is, so I’m not sure that additional characters would have looked good.

I was happy to see that Cyborg made it into the game, and he’ll probably be the least-known character of the bunch since he doesn’t have his own movie yet. That said, he did make an appearance in Batman v Superman: Dawn of Justice so maybe he’s starting to gain a bit of a following. Some will argue that only having 6 of the original 7 members of the Justice League in the game is silly and Martian Manhunter should have been included, which is a valid complaint in my opinion.

Players will probably be surprised to find that there’s only a total of 9 symbols in this game, which is definitely on the low side for an online slot these days. Here’s what we have…

  • Cyborg (Victor Stone)
  • Aquaman (Arthur Curry)
  • Green Lantern (Kyle Rayner)
  • Flash (Barry Allen)
  • Wonder Woman (Diana Prince)
  • Batman (Bruce Wayne)
  • Superman (Clark Kent)
  • Superhero Silhouettes (Wild)
  • Daily Planet (Bonus)

Superman is the strongest character symbol in the game paying 300x your line bet for 5 of a Kind. He’s followed by Batman, Wonder Woman, Flash, and Green Lantern who pay 120x, 90x, 30x, and 30x your wager respectively for five in a spin. Aquaman and Cyborg round things out by paying 20x each for 5.

You should note that this is a fixed payline game so you’ll have to play all 25 lines every spin and you’ll be charged 30 coins for the pleasure. Place your bets accordingly.


In keeping with all of the other newer DC Slot games made by NextGen, there isn’t a Justice League Jackpot available. It’s a shame that this collection of superheroes wasn’t honored with a big cash prize, but I guess we’ll just have to accept it and move on.

Bonus Rounds

The biggest injustice of Justice League Slots is that there isn’t a real bonus round, and as a result there isn’t a break from the constant spinning of the reels. The majority of new DC games don’t have extra features so maybe I’m in the minority of players who actually like to mix things up with a good bonus area? I wouldn’t have thought so, but you have to assume that casino software companies research this kind of thing in order to make games that people actually want to play – I guess I’m different.

Thankfully, there are a couple of small bonus nuggets in this game, with the Super Hero Power-Up feature being one of the only ways to really boost your bankroll. This is triggered when one of the character’s symbols falls in all 3 sections of reel #1, and at least one of them creates a payline win. From there, reel #5 will mirror reel #1 and also transform into one big stacked symbol of the character, with both stacks and every other symbol of that character locking into place while the reels are re-spun. During this feature Wilds will also be locked into place as they drop. You will keep piling up winnings and re-spins as long as you get at least one of the character’s symbols or a Wild in the spin, or until the maximum of all 15 positions on the reels are full.

Another little reel bonus is the Team Rescue feature that will randomly turn a symbol on reels #2, #3, and/or #4 into a Wild, which of course gives you a few extra ways to win. There’s nothing wrong with free money and I’ll definitely take it.

Watch out for the Gamble Feature because I’m sure that some of you will be tempted like I was to risk all of your winnings on the flip of a card. You can win 2x for picking the right color of the next card and win 4x if you pick the right suit, up until a maximum of five times. It’s fun to try to double up for a while and I was kind of bored so it spiced things up, but of course I picked wrong more often than not and busted my balance.

Free Spins

The main thing you’ll be chasing in Justice League is the “Attack on Metropolis” feature which is triggered by 3 Bonus symbols in a spin, and it’ll give you 10 free games each time. Once in the feature you’ll be blasting Parademons and the evil Darkseid with a devastated Metropolis smoldering in the background.

The Super Hero Spin Meter and Super Hero Spin Counter will appear on the right of the reels to display the status and details of your feature, with the meter starting at empty and the counter only set to 1. From there, Wilds that drop will charge the meter, with 3 of them pumping it up to its maximum level which will make the spin counter increase by 1 before it resets back to empty.

This continues until the freeroll is over and you’ll then be awarded your Super Hero Spins which will transform reels #1 and #5 into the same random character. All of the payline wins that have a Wild involved will be assigned a random multiplier of anywhere between 2x and 10x, with the amount you receive being displayed in the “Wild Wins” box under the Spin Meter once each individual Hero Spin has finished.

The Super Hero Spin Meter will keep charging during this feature and give you more Super Hero Spins as you earn them, and the game might even throw you an extra one after a losing spin if it feels like it, just to be charitable.

Finally, you’ll want to zap as many Parademons as you can along the way since they explode to reveal random extra free spins that will be added to your total.

As you can probably tell by this description, this is one of the most intricate free games modes I’ve played in a long time, and some of you are really going to geek-out on it.


This slot was definitely designed to resemble the modern comic books, so fans of that particular era will be very happy with its look and feel. The style of the regular game is a little bland, but I do understand that it’s all part of the general theme of what they were going for.

That said, the best graphics all occur in the Attack on Metropolis free spins mode, with the background looking fantastic with the burning buildings and swarms of Parademons flying around in the distance. And when Darkseid pops up to challenge you it’s one of the coolest visuals in the game.

All of the user controls like the Super Hero Spins meter and Wild Wins box on the righthand side of the reels look very sharp, and the other normal user controls are all pretty futuristic and blend in nicely with the other graphics.

Finally, the “JL” logo on the gold coins that shoot out for a big win are a nice touch.

Audio & Soundtrack

The main game soundtrack is a classical style of song driven by a regal trumpet and string section, that sounds like the background music in every superhero movie you’ve ever seen in your life. It fits just fine and I don’t think that we can blame the creators for not wanting to deviate from the norm.

The win audios aren’t too overwhelming in this game, although some of you will probably want to turn down the volume so you’re not blown out of your chair with the musical blasts that accompany larger wins. There’s something about win audios that software companies just can’t seem to get right.

The free spins mode brings an ominous soundtrack that will have you sitting up straight and getting ready to defend Metropolis with all your might. The synthesizer work on this one is pretty retro, so older players like me will probably crack a smile when it breaks into the funky part of the song – it definitely conjures up memories of old ’80s cartoons.

In general, the music goes from very soft to extremely loud, so make sure you know where that volume button is at all times and adjust it accordingly.

Finally, there’s zero dialogue in this game and as a result the character development really suffers. Everyone would have liked to have heard Batman hiss threats at his enemies – why not include it?


I think that Justice League Slots is primarily going to be for fans of DC Comics who are just happy to play a game that features a bunch of members of the League, and don’t care too much about an actual plot. Others will be disappointed that there’s no bonus rounds, no jackpots, and not a whole heck of a lot to keep fidgety players like me interested.

Don’t get me wrong, I think that some of you are going to absolutely love the speed and action of this slot, and there are definitely some exciting things going on. Also, there does seem to be a constant stream of larger wins in the regular game, which is probably due to the fact that there’s a small amount of symbols on the reels and there’s no bonus round or jackpot to pay for.

Ultimately, after the novelty of having 7 heroes in one game wears off, I think that most of you will be moving on to more exciting titles. This slot would have been amazing in 2013, but today it just feels lacking in some important categories.

You’re either going to love this game or hate it, and there’s only way to find out. The good news is you should know within 5 minutes which side of the fence you’re on.
