If you like the 80s arcades and sci-fi aesthetics, plus the elegant layout of minimalist graphic design, you will absolutely love Thunderkick’s Spectra slot. With a black background and bright neon outlined symbols, this innovative video slot gets back to the basics of slots machines while providing gamblers with a Tron-like experience.

The selection of this particular theme is, of course, very random. It does not feature characters, but only an overall design with a clear concept and a very clear way to pull it out.


Thunderkick is sort of a newcomer in this industry of casino software development. They started to work and provide online casino operators with gaming solutions in 2012, meaning that they only have a couple of years out in the market.

Despite their short active time, they have worked hard and smart enough to be considered by both audiences and operators as one of the best developing houses.

Their themes are very varied, and they thrive for original and unique themes and solutions. They have made slot machines about everything, from ice creams to random symbols.

We have noticed that they have the tendency to improve themselves, and we think this is due to their team being very in touch with the requirements of the audience. They develop responsive gameplays with acclaimed concepts, and they get increasingly better with time.

How to play the slot

The overall setting of the game is very simple, and if you’re familiar with slot machines, it is as intuitive as it gets. Spectra is composed of 5-reels with 4-rows, and it features 30 fixed paylines. To redeem coin payouts, you need to hit one of these fixed paylines, starting with the leftmost reel.

The variance of this game is quite high, meaning it is a very volatile slot. Keeping this in mind, Thunderkick allows players to adjust their bet size.

Special features

Even though this slot game works on a single dynamic basis, it does have amazing surprises for those who think that this is only about reel spinning.

Spectra features a Wild symbol with multiple functions, each one of them designed to enhance your payouts. This symbol is represented by a multicolored bold W, and it substitutes for any other symbol on the games.

But this Wild symbol appears only in stacks of four vertical symbols, being technically what we call Stacked Wild: a single special Wild symbol covering up entire reels. Of course, Stacked Wilds are a bigger odd-booster than simple Wilds covering up only one place in the grid.

Once you get a Stacked Wild symbol during your reel spinning in Spectra, you will notice that it triggers a new free spin. Usually, free spins are triggered by Scatter symbols, and most slot have separate icons for Wilds and Scatters. But in this case, a Stacked Wild functions both as a symbol substitute and a free spin trigger.

But there is more. During your free spins, you will notice how the Stacked Wild finds its way to the center of the grid, and gets further into the middle with every free spin granted.

Thunderkick clarifies that this feature operates as a Nudge Wild, making this single icon special feature a four-in-one combo, balancing for the high variance and the incredibly difficult odds.

Maximum payouts

The payouts provided by the Spectra slot do get a little frustrating. The high volatility adds up to paylines with low coin rewards. During a random spin, you will roughly collect a few dozens of coins, reaching the range of the hundreds only if you are extremely lucky.

The multiple features Wild symbols are quite rare, meaning that it does not appear as often as we would’ve liked.

If you’re into big bets and proving the odds are on your favor, you might want to start with small steps before jumping into big stakes.

A conservative and even shy approach is perhaps your best choice when it comes to put real money on the table with the Spectra slot.


We absolutely loved the overall concept of this game, and after giving it a few chances from different devices –both desktop and mobile- we reached the conclusion that Thunderkick’s products are as seamless as it is now possible.

Their good taste was never in doubt, but we reassured our perception with Spectra.

But as much as we loved the visuals and how reminiscent of the golden decade this slot is, we were frustrated not to get big payouts.

Of course, your opinion on this particular matter may differ from ours. If you’re a risk-seeking gambler, you will love it. If you’re a risk-averse one, you will not last more than a few spins.
