Where to play?

Justice League is a 40 payline, 5 reel high variance progressive online slots from Playtech which is part of the DC Comics brand featuring The Flash, Cyborg, Aquaman (Jason Mamoa), Wonder Woman (Gal Gadot), Superman and Batman (Ben Afleck). Just like the film, Batman and Wonder Woman team up with the mentioned super heroes to defeat the villains.

The minimum bet per spin is 40 pence up to a gargantuan £2,000 which makes it the perfect slots for high rollers. The game is available in the free mode and can be played on PC desktops and mobile phones.

We played it for free at an average stake of £0.80 per spin, the payouts we received during the main game and free spins (see screenshots) were surprisingly good making it a great game to play despite its volatility. Justice League is based on the Hollywood blockbuster film of the same name where our troop of super heroes defends earth from the evil Steppenwolf and his henchmen the parademons.

When it comes to in-play bonus modes, Justice League has a Super Hero Re-spin and 6 free spins features each represented by a super hero that’s triggered by 3 or more scatters.

The free spins mode that’s the most volatile and hardest to trigger is the Batman one, it rewards 2 free spins and comes with a 2×2 giant frame on each free spin-the payouts here can be spectacular. The game also has 4 progressive jackpots that’s triggered randomly.

The biggest payout we received during the base game was £13.68 (17x stake). The graphics and animations are well-crafted not that we expected anything less from Playtech. Symbols across the reels are The Flash, Cyborg, Aquaman, Wonder Woman, Batman, the Just League logo (wild) and scatters (blocks).

The super hero logos offer large cash prizes when they appear stacked up to 4 high on the reels. The average payout percentage (RTP) of Justice League slots is 95.3%. The Batman symbol pays the top cash prize, 5 of them at the maximum wager pays 500 coins followed by Superman which pays 400 coins for 5.

Game Play

When you click on the ‘Info’ box the paytable of the progressive jackpot slots opens up indicating the payouts each icon offers and it tells you how its bonus features are triggered. The smallest stake per spin is £0.40, when you click on the -/+ buttons you can reduce or increase your average stake per spin.

The Auto Play feature spins the reels automatically from 10 to 99 spins while the ‘Turbo Mode’ spins the reels faster. We recommend you play the game with a bankroll of at least £250 to gain the most out of the slots. Reason being the free spins takes in excess of 150 spins before one is triggered. If you play Justice League at the lowest bet per spin it will cost you at least £60 (150x£0.40) to trigger the free spins.

Bonus Modes

Super Hero Re-spins

The Super Hero re-spins is activated randomly during the base game, once triggered a re-spin is given any super hero can be transformed into a wild randomly. The featured can be re-triggered up to 5 times all the super heroes can be turned into wilds.

Free Spins

There are 6 free spins features each is based on a super hero along with wild symbols. Based on our game play we noted that it takes around 150 money spins to initiate a free spins feature which is triggered by 3 scatters. What we like about the free spins is that an unlimited amount (re-triggerable) of free spins can be won.

The Flash Free Spins

The free spins mode is triggered by 3 scatters which awards 15 free spins, should a super hero pitch symbols are transformed into wilds. In the event 3 scatters appear 15 extra free spins is given making it 30 in total. But, should 2 scatters appear whilst the free spins is underway another 3 free spins is awarded. What strikes us about the free spins is that an unlimited amount of them can be won making the payout potential astronomical.

free extra games

It took us around 150 (£120) spins to initiate the Flash Free Spins mode, we managed to notch up 25 free spins and a total win of £76.98.

Cyborg Free Spins

This free spins mode gives you 12 free spins, a super hero that appears on the reels transforms additional symbols into wilds. Should another 2 scatters appear you’ll pocket another 3 free spins.

Aquaman Free Spins

10 Free spins are given here, paying icons that pitch transforms matching symbols into wilds-2 or more scatters awards extra free spins.

Wonder Woman Free Spins

Once triggered 7 free spins are given, on every free spin there’s 1 to 5 feature frames and when 2 or more scatters pop up on the reels additional free spins will be awarded. The feature can be re-triggered should another 3 scatters pitch awarding 7 free spins making it 14 in total.

Superman Free Spins

You’ll bag 5 free spins once the feature is played. All symbols become wilds once a super hero appears in the frame. This is the start of the ‘Big Money’ free spins because on every free spin a giant 2×2 feature frame is displayed.

Batman Free Spins

Of the lot this free spins feature is the most difficult to trigger (highly volatile) and the most rewarding. Two free spins are awarded, on each respective frame super heroes will be turned into wilds.

Progressive Jackpots

This is where the biggest payouts lurk, 1 to 4 progressive jackpots (Mini, Minor, Major and Grand) can be triggered randomly. Once a jackpot game is triggered a new screen opens up where jackpot symbols must be picked.



Justice League not only looks good it’s fitted with a bunch of bonus modes that’s conducive to any bankroll. Of the free spins the Batman feature pays the best thanks to those stacked wilds.

The best bit is you can win the progressive jackpot on a single spin which is life-changing to say the least. Patience is key here so don’t expect a payout on every spin.

In our opinion it’s the best DC Comics slots Playtech rolled out. If you play this progressive jackpots slots make sure that the online casino you’re about to play it at pays progressive wins in one lump sum.
