Spectra Slot Detail

A simple 5×4 reel game, the Thunderkick Spectra online strips things back to the basics, but with just the right nudge.
Before you quickly whisk yourself away in need of something a little more complex, we’d advise you to continue to read our Spectra slot review.

Just because this Spectra mobile slot is basic, doesn’t necessarily mean it’s boring and not worth playing. Yes there’s no free spins or bonus games as such, but the wilds will steal the show with a top prize of up to 240,000 cash.

But before we get in to those, let’s talk theme, which look as retro as the Arcader slot by the same provider.

The Spectra slot shows off all the colours of the spectrum

The 5 reels and 30 paylines here are covered with simple shapes, some from popular classic slots like the BAR, 7’s and golden bells symbols along with four leaf clovers as the highest paying of the game.

Then we head in to the simple shapes like pentagons, diamonds, squares, triangles and circles, which all glow a little and are the lower paying of this Spectra casino slots.

All cleverly covering most of the colours of the spectrum, where this casino game got its name. Granted, it’s not as imaginative or crazy a theme as something like the Toki Time slot.

But with some funky sounds and simple gameplay, all types of players can enjoy the joy of spinning for a wild win.

It’s all about the wilds

The main bonus feature throughout this Spectra slot machine is that of the wild symbol which comes stacked four symbols high and with a few special features of its own.

Namely wild respins and wild nudges.

Whenever a wild shows up partially on screen, it will reward a free respin with the wild in place. If a new wild shows up on the respin, you’ll be awarded another respin, and the wild will continue to nudge up or down by one symbol until the wild fills the reels or you get no more respins.

It’s like a clever version of the wild respins in the Magicious slot, or even Starburst.

The fact this is a feature that occurs regularly enough in this Spectra slot machine provide some well needed wins no doubt help make this new Thunderkick game very playable.

Wilds: The multicoloured W is wild and substitutes for all other slot symbols.

Wild Nudge & Wild Respin: When a wild appears it will provide a respin, if you get more wilds on the respin the wilds will nudge up or down by 1 symbol to provide bigger wins and another respin.

There is the potential to get a Whole screen full of wilds but that would be a truly lucky wild spin.

Spectra Review Conclusion

The Thunderkick Spectra mobile slot is a simple casino game where the wilds and simple game play steals the show.

A multicoloured game that provides all types of platers with some decent action and a chance to spin from as little as 0.

But if you like your slots with a little more colour, you could always try out the Zoom slot from the same provider with stacked wilds and super massive symbols for even bigger wins.
