This online slot from Yggdrasil Gaming recounts the tale of a world invaded by creatures that can transform into humans. These are called Reptoids and uncovering them will prove lucrative as it will reward you with free spins and cash prizes.

Reptoids is a five-reel, three-row, and 20 fixed payline game. Those symbols spin within a machine that is designed to identify those alien intruders while the backdrop is that of an industrial street in an anonymous town.

Before you can join this undercover unit, you must first set your bets. By clicking on "Coin Value +/-" you can set coins size which goes from the uncommonly 0.005 to 5. "Max Bet" is utilized to set the maximum bet allowed, and "Spin" gets the reels moving. "Autoplay" is used to turn the reels automatically without interruption for a pre-determined number of times.

This game combines an atmospheric theme with some unique and innovative mechanics to deliver an exciting new gaming experience. The game takes two thematic ideas and melds them in order to create this unique world. First, there’s the “aliens in disguise” concept, which is a common staple of science fiction. However, there’s also the fact that this game is a bit of a period piece: the machine’s action is meant to take place in the 1960s, giving this slot an antiquated look and feel.

If you’re ready to combine your online slots play with a robust dose of alien conspiracies, then you’ll definitely enjoy playing Reptoids. This game developer rarely disappoints with their productions, and the fact that they’re using such a dynamic theme that features loads of creative potential will really get players excited to see what they come up with here.


The six high-value symbols are all Reptoids in human form – businessmen, soldiers, nurses and the like – while the lower values are four military medals of various hues. Gilded symbols depicting Mutants is the wild and it can substitute for all regular symbols in the game. Gilded Coin is the Scatter symbol and it can form scatter wins when you land 2 or more symbols anywhere on the reels.


Wild Reptoids

Reptoids comes with a Repto Detector feature – a detector frame moves to a random position on each spin in the base game. The character landing in the detector frame will turn all instances of that character into wilds (wild aliens). The wild takes the place for all other symbols, except the scatter, to form winning combinations.

Back to the gold coin scatter – if you land the scatter in the detector frame, you will trigger the Free Spins feature with seven free spins awarded. The Repto Detector feature also applies here but uncovered Reptoids will become sticky wilds for the duration of the feature – this means you could end up with plenty of sticky wilds on the reels.
