Wild Robo Factory Slot Review

Released June 2019

The Wild Robo Factory slot game is produced by Yggdrasil Gaming. Yggdrasil Gaming take their name from Norse mythology where Yggdrasil is a magical tree where dragons lived and Odin sacrificed himself. Yggdrasil Gaming are one of the smaller slot development companies on the market at the moment – primarily focusing on lottery and scratch card game – and do not offer a full casino platform. They lease their games out to casinos using other platforms as a bolt on package. Yggdrasil Gaming publish the Return to Player/House Edge of their slot games within the game help file. The House Edge of Wild Robo Factory is 3.6%.

Wild Robo Factory is a 5 reel game that is 4 symbols high. The game has traditional paylines, using a total of 25, playing from left to right.

Special Symbols

Valuable Symbols – The most valuable symbols in this slot are the robot pieces, with the red robot pieces being the most valuable of the whole lot.

Wilds – The Wild symbols in this slot game need quite a bit of explaining. At the very bottom of the reels there is a conveyor belt where robot parts, that are all Wilds, move along towards the left-hand side of the reels, before disappearing off the other end of the conveyor belt. There will not always be Wilds on the conveyer belt, but if there is then the robot pieces will stop somewhere on them. All the robot pieces vary in size, from 1 symbol high to 4 symbols high, meaning that when the conveyor belt stops the robot piece can covering anything from 1 space on the bottom of the reels to filling an entire reel. It is worth noting that the symbols can stop more than once and there can be more than 1 present on the reels at once. There are 4 different types of Wild Robots that can appear on the conveyor belt:

Wild Robos – These are your standard Wild Robot symbols. They can appear from 1 to 4 symbols high and will substitute for all other symbols.

Twin Wild Robos – These robots come in pairs of identical heights, meaning that they sit on two adjacent reels instead of 1. They can be 2, 3 or 4 symbols high and work as standard wilds, substituting for all other symbols.

Wild Pattern Robos – These robots come in the form of a cluster that uses 4 Wild Robo symbols. They will be connected randomly, forming all sorts of different patterns. Again, they act as the standard Wilds do, substituting for all other symbols.

X2 Multiplier Wild Robos – These are exactly the same as the Wild Robos, except any wins that they help to form will win double the usual amount.

Free Spins – The Free Spins symbol is a “Monitor” and you need to land three or more of them on a single spin to trigger the feature. They can appear on the reels as normal and on the conveyor belt beneath them.

Bonus Features

Robo Re-spins – Robo Re-spins are triggered at random. When this happens Wild symbols will appear on the conveyor belt. You will be given free re-spins until the Wilds fall off the left-hand side of the reels.

Symbol Swap – This is another random feature but one that will only trigger is you for a win using low paying symbols. If you do this and you are lucky enough for the random Symbol Swap feature to trigger, all the low paying symbols will be replaced with high paying ones.

Free Spins – If you trigger the Free Spins feature you will not be given a set number of Free Spins. Instead you will be given a set number of Robos: 5 for 3 triggering symbols, 10 for 4 triggering symbols and 15 for 5 triggering symbols. This means that your Free Spins will end when all of your designated Robo Wilds have fallen off the left side of the reels. Free Spins can be re-triggered and will be issued once the current Free Spins have finished.

System Overload – This feature is triggered randomly during the Free Spins feature. When it happens Wilds that have fallen off the left-side of the reels will return in the opposite direction, essentially giving you more Free Spins. This can only happen if at least 3 Robo Wilds have fallen off the left-hand-side of the reels. The feature can trigger a maximum of 4 times during the Free Spins.


What I really like about Wild Robo Factory is just how aware of its own theme the slot is. It is set in a robot factory and as such the central feature involves an assembly line in a robot factory. Time and effort have clearly gone into ensuring that this game lives up to its title. The house edge is low, there are a number of random features. There’s little here not to like.
