Theme

7.5 

Spectra greatly reminds classic retro games where you need to shoot asteroids and aliens. Symbols have simple shapes. But their neon coloring and overall ambient light look very cool. Music adds that mood of space travels, which finishes the overall game design.

As for symbols, there are 9 regulars and the Wild. You need common symbols to gather combinations. The value depends on the amount of them. By dropping 5 of the same symbols, you can get a 1.4x, 1.6x, 1.8x, 2x, 2.2x, 3x, 4x, 7x, and 10x bet multiplier.

A Wild symbol commonly substitutes any other symbol and grants you a 20x multiplier if you gather 5 of them. Besides, it can trigger additional features like Wild Nudge and Wild Respin.

About Thunderkick

When you see a large company with years of success it is difficult to imagine how small it was before. In fact, Thunderkick started as a couple of friends who have needed skills and knowledge for making the first slot. Then, the company started obtaining licenses like MGA, ONJN, and UK Gambling Commission to operate in different parts of the world. As for other slots you should take a look at Birds on a Wire and Flux.

Max Win

8 
Spectra allows plays to get the max win of 2,400x the bet.

Overall Rating

7.8

In Spectra, you can enjoy the neon and space theme. Thunderkick has developed an exciting game with nice music. However, low-paying symbols are not very impressive. With medium volatility, you may not get grand prizes. However, the spin outcome can greatly change when you drop Wild symbols.

Spectra is a simple slot. But even without many innovative features, it can still entertain you. It has a convenient user interface, which makes your gameplay comfortable. And that is the reason why we recommend trying it.

Hits
Nice design and exciting music
Good correlation between RTP, volatility, and max win
Misses
Lack of bonus features
