Game Review: Spectra

If it’s a futuristic neon slot adventure that you’re after, then Spectra should be right up your alley. Powered by Swedish gaming heavyweight Thunderkick, the title is one of the best online slots for winnings without a bonus round. This 5-reel, 4-row, and 30-payline game may be simple, but the Wild Respin feature certainly packs a punch, with payouts of up to 2,400x your stake per spin.

With bright and colourful graphics, straightforward gameplay and a whole heap of wicked Wild features, this is one slot you don’t want to miss out on.


Spectra is a futuristic, neon slot game with 30 paylines and a maximum payout of up to 2,400x your stake per spin. Think of it as a mash-up of a classic, simple fruity theme with neon, modern visuals: the graphics are a real treat and work wonders. When it comes to the features, the first thing that you’ll notice is there aren’t any bonus features or scatter symbols. However, the main attractions are wild nudges and wild re-spins, which hit at regular intervals and more than make up for that. We’ll discuss the wilds in more detail in the bonus features section below. 

This game boasts an RTP (return to player) of 96.4%, which is above average for slot games. Spectra is of a high variance, so while the game doesn’t pay out all that often, the payouts are fairly substantial when it does. It can be played on mobile, tablet and desktop devices from between 10p and £100 per spin.

Thunderkick is known for producing stylish, simple games with high-quality performance and crisp graphics, and this is exactly what you get with Spectra. The colourful graphics and ease of gameplay, as well as the enticing Wilds features, make this an exciting slot with potential for big wins. If you want to try it out for yourself, you can claim your 100 free spins at our jackpot mobile casino and see how much you enjoy Spectra.

Graphics and theme

If you’ve always dreamed of going into space, then this is your opportunity. Set against a dark blue backdrop reminiscent of the night sky, the neon symbols seem to cover all the resplendent options of the spectrum and give Spectra a distinct space-age feel. 

There are nine symbols in spectra – five geometric symbols, a clover, a bell, a number 7, a bar and a wild. The blue circles are the lowest-paying symbols and in ascending order of value, you will then find sky blue triangles, green squares, purple diamonds, and red pentagons. Then you get your higher-paying symbols in the golden bell, lucky red 7, white BAR and the green clover, which will pay out 10x your total stake per spin for 5 on the reels.

The rainbow-coloured W is the Wild symbol. This replaces all other symbols on your reels, and it will always appear in stacks of 4. If you land 5 Wild symbols on your payline, you’ll get 20x your total stake.

Of course, you’ll notice that there are no scatters or proper bonus features in this game, but don’t stress too much. The Wilds come with enough re-spins to make up for this.

How to play Spectra

The gameplay in Spectra is pretty much as simple as they come. The betting size goes from 10p to £100 per spin, and like most of the games on our site, you can also use your free daily spins, or pay to play on mobile, desktop or tablet.

The action button gets the game started and, from left to right, you’ll need to try to land as many of the same symbols across the reels as possible. Five symbols across the paylines will give you the best payouts, and of course, there’s the amazing Stacked Wilds feature that will help you form winning combinations more easily. More on this below.

Bonus features

Any time a W symbol lands on the reels, it will trigger the Wild Re-Spin feature, which will give you a free re-spin. During each one of these re-spins, the Wilds will move a slot closer to the centre of the reels – this is known as the Wild Nudge feature. As they move across during the re-spins, they create space to the left of your reels and help you work towards filling your reels with Wilds. If you manage to get 5 Wilds on your reels, you’ll trigger the maximum payout of 2,400x your stake.

Luckily, these Wilds come along quite regularly, so you won’t be waiting long to get your chance at a re-spin. Keep in mind, however, that this is a high-variance slot, and you might get a couple of smaller payouts before you get the occasional big wins.
