Theme of the Game

Thunderkick team are not sleeping this summer, as they have released yet another imaginative and sharp-looking slot. This time they bring a new glow to the old arcade games.

Actually they packed neon glowing icons in an arcade-style 5×4 grid giving it a futuristic feel. Once again Thunderkick managed to surprise us.

Spectra offers basic game play options with a slightly unusual Wild feature and re-spins. You might be surprised to find out that there are no Scatters or Free Spins, but even so, you might have a good time spinning this neon pokie.


Thunderkick are Stockholm-based gaming developers founded in 2012 by an enthusiastic team of experienced gaming professionals.

In the short time they have been on the gaming scene they have managed to establish themselves as a trustworthy developer and unique in many aspects.

Their signature style when developing slots is superb graphics and innovative approach to redesigning the special features, as well as basic functionality of the game.

With just the right doze of originality and humour their slots are endless sources of entertainment. If you like Spectra, you can also try Babushkas, which was released this summer.

How to Play It

Just like all of Thunderkick’s slots it is pretty easy to get the hang of Spectra. The game comes with typical menu bar keeping track of your bet and balance with the option to set the bet size and also the Autoplay option which can be set to even 5000 spins.

The main game features pretty basic symbols: a multi-coloured letter W for a wild, BAR icon, number 7, a bell, a clover and geometric shapes of pentagram, diamond, triangle, and circle as the lowest paying icons. Honestly, the fact that there are no play cards symbols is refreshing.

The highest paying symbol is naturally the Wild and it will return your bet 20 times for five of a kind. Next in line on the payouts table is BAR icon which pays 10, while number 7, bell and clover pay 7, 4 and 3 respectively. Like we mentioned, there are no Scatters or any other special symbols.

Special Features

It seems that lately Thunderkick are opting for minimalistic approach to the base game with an addition of one innovative feature. Spectra proves it with its Wild symbol which introduces a couple of twists to the base game.

In this intergalactic 5 reel and 30 payline slot everything is based on Wild characters that appear quite regularly throughout the game.

Each time they appear Wilds are stacked and they award a re-spin which, in a way, makes up for the lack of Free Spins.

The most interesting aspect of this Wild feature is Wild Nudge, a new role of the Stacked Wilds which shift towards the centre in order to make more winning combinations. Every time a Wild appears it will move up or down to be closer to the middle and increase your chances of payouts.

If the re-spins bring additional wilds the free play will re-trigger and the new wilds will move to the middle of the reels. This means that in theory you could fill the entire screen with wilds, but, honestly we don’t see that happening soon,

Once you start spinning this feature it turns out to be quite amusing especially with the addition of colourful laser beam effects and the sci-fi soundtrack.

Maximum Payout

Despite its pretty basic game play, Spectra boasts a top prize of up to $240,000 with the bet ranging from $0.10 to $100. It sounds good in theory, but when you know that you will be relying only on Re-spins and Stacked Wilds, it is clear that this jackpot won’t come easily.

Still, the Wilds appear often enough to promise decent payouts owing to the fact that they replace common symbols to form winning combos, while five Wilds return your bet 20 times.

With the return to player 96,4% we believe that you will be satisfied with the payouts even if you don’t hit the top prize.


Sometimes less is more and Thunderkick have successfully applied this to their new release, Spectra. With seemingly no special features at all, you might think that this slot has nothing to offer except for its looks.

But guess again, in the midst of all the flashy geometric shapes comes rainbow-coloured Wild to guarantee re-spins and payouts with it stacked on the reels and moving to suit your play best.

Spectra is a medium variance slot that will appeal mostly to those who like traditional fruity slots re-designed to fit the modern technology era.
