Attack on Retro Slot Review

Released March 2020

The Attack on Retro slot game can be found at Microgaming casinos. Microgaming as a standard now publish the house edge information of all their slots at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos). As such we can say that the House Edge of Attack on Retro is 4.42%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.


Attack on Retro is a science fiction themed slot that reminds me of the kind of science fiction films that came out in the 80s. That must be where the name of the slot comes from, with characters set in a futuristic world but dressing a bit like they did 3 decades ago.

Attack on Retro is a 5 reel game that is 3 symbols high. It uses 10 paylines, playing from left to right.

Special Symbols

Wilds – There are 2 Wild symbols in this slot, “Billy” and “Jesse”. Both of them can come 1, 2 or 3 symbols high and they are both worth the same amount. You can combine the 2 different Wilds for a Mixed Wild win that is worth half the value of a standard Wild win. They will substitute for all symbols other than Scatters.

Scatters – The Scatter symbol is the “Free Spins” symbol. 3 or more of them anywhere on the reels will trigger the Free Spin feature. “Free Spins” symbols only land on reels 2, 3 and 4.

Bonus Features

Hyperspins – After any non winning spin you can choose to respin an individual reel at a cost specified beneath the reel. After that respin if you don’t win again can choose to spin again. It is worth noting that using the respin function will reduce the RTP significantly so that your house edge drops from 4.42% – 3.92%. If you alter the size of the bet you will end forego the respin function.

Random Wilds – Random Wilds can trigger in both the base game and the Free Spins. When the feature does trigger it will happen completely at random and the small robots sitting at the sides of the reels will add up to 15 Wilds in the base game, 3 Wilds on a respin or 9 Wilds during the Free Spins.

Free Spins – If you trigger the Free Spins you will need to choose between 2 Free Spins at x5 the bet, 5 Free Spins at x2 the bet or 10 Free Spins with no multiplier. During the feature reels 1 and 5 will be fully stacked with a “Billy” and a “Jesse” Wild, with the 2 of them capable of switching reels. If you land 2 or 3 “Free Spins” symbols during the feature you will be awarded with 5 or 10 additional Wilds respectively.


Attack on Retro is a decent offering from Microgaming. It looks the part, reminiscent of slightly more optimistic Blade Runner. The features you get are quite varied, ranging from Hyperspins, Free Spins, Wilds to Random Wilds. The significant reduction in house edge when playing the respins is worth noting, to extent that you really need to playing them if you want to get the most out of this slot.
