Theme and Visuals

Welcome to Retro, a neon-lit city about to be taken under siege, unless you stop it!

The game looks like a futuristic slot machine, with a retro, yet sci-fi impact on its design. There are neon-like decors and you can catch a glimpse of the city in the background, which makes everything stand out graciously. The reels are decorated with fluorescent lights and 2 alien robots roaming on each side. Regarding the symbols, Billy and Jesse will accompany you on the mission, equipped with hoverboards, neon boom boxes, robot hands, and electric keyboards, to help put an end to this invasion.

What adds to the excitement is the punk rock, electronica, and friendly robot voices soundtrack, syncing flawlessly with the gameplay.

Start spinning the reels to discover the numerous bonus features prepared for your arrival!

Special Features

Attack on Retro slot won’t let you confront the bad guys without the latest weapons and superpowers, which is why you shall receive some of the best features:

Respin feature

The Hyperspin is not a new feature for Microgaming slots, as we have enjoyed it in many of its other amazing slots, such as Book of Oz. How does it work?

At the end of each spin, you can respin any of the 5 reels, one at a time. The action can be taken by pushing the special button found at the bottom of each reel and it can be repeated until a win or a bonus feature is triggered. For example, if you have four high-win symbols and you’re looking for the fifth, re-spinning will increase your odds of hitting five. Like all good things in life, this feature will cost you. Though, using this option will allow you to hit a higher return to player percentage (RTP).

Random Wilds

The feature can be triggered in both base game and free rounds game. During this feature, pay attention to the robots on the spinning reels, as they will turn wild every time a laser beam hits them. You can obtain up to 15 wilds in the base game and 3 on a re-spin. A maximum of 9 wilds can appear in the spins round, on reels 2, 3, and 4.

Free Spins

Once you land three scatters on reels, a new screen will open, triggering the Attack on Retro free spins. You must then choose from:

  • 2 spins with a 5x multiplier;
  • 5 spins with 2x multiplier;
  • 10 free rounds with 1x multiplier.

Wild Reels

During Free Spins, both reels 1 and 5 are fully wild, randomly change between Billy and Jesse. The Wilds are available in numerous variants, appearing 1 to 3 symbols high on the reels. Both characters will be used as substitutes and if they end up creating their own combinations, up to 100x the stake will be paid on each line.


The gameplay is as compelling as the visuals and bonus features, offering an incredible slot with 5 reels, 3 rows, and 10 paylines. Wins are awarded for 3 to 5 matching icons on a line, from left to right.

The game has high volatility and, because of the hyper spins mechanics, the return to player percentage can fluctuate from 95% up to 96%.

How to Play

As the aliens prepare for the attack, you should set your bet prior to spinning the reels from 0.10 to 20 credits or just push the Max Bet button if you want full power.

There’s a simple Autoplay function where you can opt for 10, 25, 50, up to 100 spins and if you are impatient, you can spin using the Quick Spin function for a quicker play. Don’t forget that the re-spin function will be at your disposal, by pushing the button of each reel. Also, note that Attack on Retro slot machine free play is only here to entertain you, and the winnings can’t be withdrawn.

That being said, smash the middle play button and spin those reels as the city’s life depends on it!  


Travel back to the future and encounter the most famous symbols of the 80s with a little twist and increased wins. The maximum credits brought by the 2 groups of icons are:

High win:

  • Hoverboard: 400;
  • Electric keytar: 240;
  • Stereo: 240;
  • Robot hand: 120.

Low win:

  • Ace: 60;
  • King: 50;
  • Queen: 40;
  • Jack: 40.

The two main characters, Jesse and Billy, are the Wild symbols and can substitute any symbol, apart from the scatter and other Wild. Besides this feature, each Wild brings a maximum of 1000 credits each when encountered five times on the reels. Both wilds can also appear mixed which will increase your chances of winning.

The last but not least symbol is the Scatter. Presented as the Free Spins logo, it can appear on 2nd, 3rd, and 4th reel. Three scatters will trigger the free rounds selection, offering different multipliers to choose from. Prepared to board the journey back to neon age?
