Retro Galaxy Slot Review

Released August 2020

The Retro Galaxy 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 Retro Galaxy is 3.95%. 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.


Retro Galaxy is a science fiction slot, taken straight from an 1980s guide to how to making science fiction.

Retro Galaxy is a 5 reel game that is 3 symbols high. Instead of paylines, you form winning combinations when you land 3 or more matching symbols across adjacent reels, with 243 different ways to win in total.

Special Symbols

Wilds – The Wild symbol will substitute for all symbols other than Scatters and will only appear on reels 2-5.

Scatters – The Scatter symbol is the “Free Spins.” 3 or more of them anywhere on the reels will trigger the Free Spins feature. In the base game it can appear on all reels but during the base game it will only appear on reels 1, 3 or 5.

Bonus Features

Rolling Reels – Every time you land a win the symbols involved will disappear off the reels and then they will be replaced by new symbols, giving you another chance to win. This process continues as long as you keep landing wins and multipliers are also applied to the rolling reels, increasing in value with each drop:

Initial Spin – 1x

1st Rolling Reel – 2x

2nd Rolling Reel – 3

3rd and all subsequent Rolling Reels – 5x

Rolling Reels in the Free Spins – The Rolling Reels improve during the Free Spins. The initial spin is already worth 2x the bet and all rolling reels after this will increase the multiplier by 1, up to a maximum of 15. The multiplier will not reset when the spin ends, but will obviously do so when the feature ends.

Free Spins – 3, 4 or 5 Scatters will trigger 10, 15 or 20 Free Spins respectively. Landing 3 Scatters during the feature will award an additional 5 spins but Scatters can only appear on reels 1, 3 and 5 during the Free Spins.


Retro Galaxy is nothing you won’t have seen before. It is a well-enough designed slot that uses win ways instead of paylines. It comes with Free Spins that can be retriggered and it comes with Wilds. There are rolling reels and those come with a multiplier that is applied following each rolling reel. The house edge is offering fairly average value for money and fairly average is pretty much where I would want to leave off with this slot.
