Triple Edge Studios have produced a number of top games for Microgaming in recent times including the likes of the Book of Oz, Lara Croft Tombs and Temples and the scary Halloween slots. Their latest offering takes us into the 22nd century to Retro City and two inhabitants, Jesse and Billy, who are doing their level best to fend off a robot invasion of their home city. This is a 5×3 reel slot with 10 pay lines in play that features a potential jackpot win of 5,000x your stake, high variance gameplay and betting starts at 0.10p per spin.

Theme and Presentation

The theme of the slot is based on a robot attack on Retro City and that city is very much entrenched in the 1980s, which means plenty of 80s pop culture referenced in the game. The soundtrack is especially evocative, with a very 1980s electronica pop music background to the game fitting it perfectly. The rest of the slot is also nicely done with lots of use of neon and bright vibrant colours, plus references to the 80s, namely in the symbols used on the reels.

Overall, the slot looks and sounds superb and with simple to use controls, it is equally easy to play too.


There are 11 symbols on the reels in total, eight of which are standard symbols, plus two Wild symbols and a Scatter symbol. The eight standard symbols start with the four lower paying symbols which are the Jack, Queen, King and Ace. These offer wins from 0.6x your bet up to 3x your bet in the base game.

There are four higher value symbols in the game too and these are a glove, a ghettoblaster, a musical instrument that looks like a keyboard crossed with a guitar and what looks like Marty McFly’s hoverboard from the Back to the Future film franchise. In terms of win size, wins range from 1x your bet to 20x your bet with these symbols. However, with symbols stacked and in conjunction with Wilds and whatnot, it is possible to win across multiple lines, which is how the better value wins in the game tend to be landed.

Wild Symbol

There are two Wild symbols on the reels in the Attack on Retro slot game. They are named after the two defenders of Retro City, Billy and Jesse. These Wilds can be single symbols or stacked two or three high (so they can cover a reel entirely). If you can land five of the same Wild symbol across the reels, then you trigger the main game jackpot prize of 1,000x your bet.

However, you can also mix and match the Billy and Jesse Wilds, but when they both form part of a win, then the amount you win is half the amount you would land when using just one of the Wilds.

There is also a randomly triggered Wild Bonus feature in the game which occurs when the robots launch an attack on Retro city. When this occurs all 15 symbols on the reels will turn into Robot Symbols and then Jesse and Billy will blast them with lasers. Every robot they hit with a laser will turn into a Wild and when the robot’s retreat, these Wilds can be used with the symbols on the reels to create a win.

Free Spins Bonus

To land the Free Spins bonus, you need to land the three Free Spins bonus Scatters on the middle reels in any position. When you do, you then select which of the three Free Spins bonus game you want to play. Your options are:

  • 2 Free Spins with a 5x multiplier
  • 5 Free Spins with a 2x multiplier
  • 10 Free Spins with a 1x multiplier

The first of these bonuses offers the only shot at the 5,000x top prize in the game, with the other rounds offering top prizes of 2,000x and 1,000x respectively.

One nice touch is that you can trigger 5 or 10 more Free Spins in the bonus round by landing two or three of the Scatter symbols on the reels again during the bonus feature. Furthermore, for every Free Spin, the first and fifth reels are Locked Wilds and will be randomly selected as either Jesse or Billy Wilds for each spin.

Other Bonuses and Information

The other main bonus on the Attack on Retro slot is the Hyperspins bonus feature. This is available after every spin and essentially, it allows you to spin just one reel, for a stated amount of money, in order to try and land a better value win, or maybe trigger the Free Spins bonus game.

The higher the value of a potential win you can land by spinning one of the Hyperspins reels, then the more it will cost you per spin and it is up to the player to decide whether it is worth paying the extra cost to spin that one reel, or whether to simply play another standard spin at the standard game rate.


Editor's Review

Triple Edge Studios have created another outstanding game here, combining several different elements from standard slots and giving them a twist to create a truly enjoyable and engaging game. The jackpot isn’t particularly high but the high volatile nature of the slot will appeal to players who like rarer big wins in particular. This is a beautifully presented and designed slot that will have certain long term appeal.
