Reptoids is a 5 reel, 20 payline slot from Yggdrasil Gaming that can be played on all devices from 10p to £100 per spin. With a 1960s style, it’s about aliens who walk among us as they attempt to take over the world. It comes with a Repto Detector feature which sees high paying symbols and all instances change into wilds. It also has a Free Spins feature which gives you up to 13 free spins as well as sticky wilds.

Visually, Reptoids is excellent as you’d expect from an Yggdrasil Gaming offering – set in the 1960s, it’s all about Reptoids who are taking over the world. With a Men in Black feel, the Reptoids are in disguise as humans on the reels – symbols include cops, nurses, scientists, generals, reporters and presidents. You also have nickel, bronze, silver and gold military medals which are low value symbols.

The president is the highest value symbol giving you 50 times your stake for 5 across a payline. The gold coin is the scatter symbol – 2, 3, 4 or 5 across a payline will give you a whopping 10, 100, 1,000 or 5,000 times stake win! The scatter only appears in the base game by the way.

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 substitutes for all other symbols, bar 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 7 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.

Furthermore, if you detect 2 Reptoids, you will be rewarded with 2 additional free spins – if you uncover all Reptoids, you will win an extra 6 free spins giving you 13 free spins in total.

I really like Reptoids – it looks fantastic and has superb bonus features. Medium variance, you can win up to 5,000 times your stake in the base game if you manage to get 5 scatters across a payline. In the Free Spins feature, you can win up to 1,000 times your stake on each free spin if you fill the screen with high value president symbols.

Overall, Reptoids is another excellent slot from Yggdrasil Gaming which is a welcome addition to their superb portfolio. If you like aliens, I recommend you try Space Invaders from Playtech (which is based on the 1986 film) and Reactoonz from Play ‘N Go.
