Where to play

Design & Symbols


To be fair this is exactly how you might expect a game called ‘Attack on Retro’ to look. The scene is one of an apocalyptic future hellscape with rising smoke and steam against a backdrop of futuristic-looking buildings. A huge setting sun illuminates an otherwise bruised purple sky while helicopters patrol from up on high.

The board framed in narrow, neon blue piping. Small, mechanical crab-like aliens peek over the left and ride sides of the frame, watching the action on the board. They scurry up and down, waiting to attack. The soundtrack is also what you’d expect, a high concept piece of electronica – like a cross between Jan Hammer and Depeche Mode. In other words, very 80’s.

Low value symbols are neon royal playing card values J-A. High value symbols are a robot arm, a purple and blue neon ghetto blaster, a guitar keyboard, and a hoverboard. The hoverboard is the most valuable regular symbol, paying 20x the stake for 5 on a payline.

The wilds are the two heroes, Billy and Jesse. Billy is sporting a robot arm from the elbow down and is wearing a red and grey bodywarmer with a red bandana. Jesse is wearing a purple admiral’s coat and is rocking plenty of bright make up to go with her coiffed purple and green haircut which I’d imagine uses up a fair amount of mousse to hold in place.

Both heroes come fully stacked and pay 100x the bet size for 5 on a payline. A combination of Billy and Jesse symbols pays 50x for 5 on a Pauline. The scatter is a neon sign spelling out “FREE SPINS”. Scatters appear on reels 2, 3, and 4.

Special Features

  • Hyperspins
  • Random Wilds
  • Free Spins


The Microgaming Hyperspins is something of a regular feature for Triple Edge Studios these days, which you might most recently remember from January’s African Quest as well as their most popular slot Book of Oz. For a price, you can respin any of the reels. The cost of a respin is shown at the bottom of each reel and is linked to how valuable a respin may potentially be. For example, if there are two scatter symbols on the reels then the cost to respin any other reel is going to be high considering the value of the potential reward. Similarly, spinning a reel when the other 4 contain the same high value symbol is likely to be expensive. When a Hyperspin brings in a winning combo you have the option to respin again to try for another win. Note, however, that only wins which include the Hyperspun reel are paid.

Random Wilds

The Random Wilds feature is triggered when the scuttling robots either side of the board both come to rest facing the middle row. The red attack warning flashes up before up to 15 robots appear flashing across the board. Lasers operating from one or both sides of the board fire at the robots and any which are hit (up to the full board of 15 symbols) become wilds for the next spin. This feature occurs in both the base game and free spins round.

Free Spins


3 scatters on reels 2, 3, and 4 triggers the free spins round. Once triggered you are presented with three option:

  • 10 free spins with a 1x win multiplier
  • 5 free spins with a 2x win multiplier
  • 2 free spins with a 5x win multiplier

Reels 1 and 5 are fully wild throughout the free spins round, although they alternate between 2 wild Jesse reel, 2 wild Billy reels, or a combination of both. Furthermore, as previously mentioned it is also possible for the Random Wilds feature to activate. However, as 2 reels are already filled with wilds, only the middle three rows are attacked. 2 scatters awards 5 additional free spins during this bonus round and 3 scatters adds 10 more spin.

Our Thoughts on Attack on Retro

I found Attack on Retro presents an enjoyable enough playing experience to be worthy of recommending. It is certainly among the best slots Triple Edge Studios have produced.

It isn’t going to be a world-beater, but in terms of features, design, and theme it very much holds its own. The retro/futuristic theme doesn’t take itself to seriously and there is a lot of fun to be had.

This is a volatile slot with decent potential and should appeal to a wide range of slot players. However, if you’re towards the conservative end of the gambling spectrum and want to make your bankroll last a little longer then my advice would be to steer clear of using the Hyperspins feature.

As fun as it can be, Hyperspins can easily suck you in, chew you up and then spit you out. For the less risk-averse among you, however, Hyperspins can be an exciting addition to the game, as long as you’re prepared to take hiding whilst searching for that big win.

Overall, Attack on Retro is another solid slot from Triple Edge Studios with good features, a fun theme and (for someone who grew up in the ’80s) a killer soundtrack!
