Spectra Slot

Spectra is a 5 reel, 4 row, 30 payline slot game that is powered by Thunderkick. Currently available exclusively at Casumo Casino, it can be played from 10p to £100 per spin across desktop, mobile and tablet devices. The design is fresh and clean as it has a futuristic feel.



With a techno synth soundtrack, it does remind me a little of Thunderkick’s Arcader in terms of look, feel and music – with a touch of Net Entertainment’s Starburst. Symbols on the reels include bars, 7s, bells, 4-leaf clovers, circles, squares, triangles, diamonds and pentagons – they are all minimal with a neon effect.

Spectra is a simple slot game which is all about the wild symbol – the ‘W’. The wild substitutes for any other symbol and they always appear in stacks of 4. When you get a stacked wild, it will trigger the Wild Respin feature holding the stacked wild in place and rewarding you with a free respin.

It also encompasses a Wild Nudge feature – the wild stacks will nudge towards the centre of the reels during each respin ensuring you work your way towards a fully wild reel. If you get more wild stacks, you will continue to get respins and benefit from wild reels!

Unfortunately, there is no free spins feature but the Wild Respin feature can, in effect, give you free spins as long as you get wild stacks on the respins. I love the animations and sound effects when you get a winning combination as it feels like you’re in a retro style arcade game.

Spectra may be simple but it’s a highly volatile offering with a win potential of up to 2,400 times your stake on each spin – the key to winning this amount is to get 5 wild stacks which is harder said than done. Thunderkick’s portfolio is brilliant in my opinion with Babushkas offering you something completely different that you’ve ever come across before.
