This early release from Thunderkick (2014) saw them take a simple approach to design but experiment with handing a little bit of control back to the player in the bonus round, where you get to choose the game set up and how many spins you get.

Visually, it’s not that far off NetEnt’s Starburst, though the features set it apart, it has the same hypnotic appeal.

Like all Thunderkick games this one has slick and clean design and animations with a smart, crystal clear soundtrack. The variance is on the low side of medium so you can enjoy the game without burning through your bankroll too quickly.

Expect a smooth regular pace of payouts, though there is potential to win massively in the bonus round if you can hit 48 both-way spins! In our experience it took some time to get there, but when you do the choice will be yours and you can claim more or less spins depending on your preferred reel set up.

This video slot game is available to play from 10p up to £100 per spin at any of the Thunderkick Slot Sites you can find online. As always, the team have made the game available on all devices and platforms, and ready to play for free or for real. Our full review gives you the lowdown on all the features and gameplay.

As we said, this game is not far from Starburst, though the design is a bit sparser. The reels are transparent so the symbols seem to float against a dark blue background. In fact, we are told that The Flux is made up of a river of energy-radiating crystals (the symbols) that flow through the universe.

The symbols are all crystals, from the lowest value blue (2x for five in a payline) to the top paying yellow star (24x for five in a payline). The other symbols to watch out for are the Wild (W) which substitutes for all except the Bonus, and the Bonus (B) that is the scatter.  This is the one that sets off the bonus round.

Flux is definitely not a complex slot. The base game ticks along nicely and you can pick up some fair wins when the Wild comes into play. But what really kicks off the action is landing three of more of the Bonus symbols. It can take some time to make this happen, but its’ worth the wait because the visuals are top notch, especially when you add in the extra reels!

This bonus round gives you the option of choosing from the following:

3 Bonus Symbols:

16 Free Spins with Win Both Way OR 12 Free Spins with 3 Extra Rows OR 8 Free Spins with Win Both Way AND 3 Extra Rows

4 Bonus Symbols:

32 Free Spins with Win Both Way OR 24 Free Spins with 3 Extra Rows OR 16 Free Spins with Win Both Way AND 3 Extra Rows

5 Bonus Symbols:

48 Free Spins with Win Both Way OR 36 Free Spins with 3 Extra Rows OR 24 Free Spins with Win Both Way AND 3 Extra Rows

It’s your choice, but for our money adding in more reels is definitely worth it to see how the game then looks!


The great thing about Thunderkick slots is that they all have their own unique characteristics. Whilst Flux is not perhaps as jam-packed and crazy as later releases, it nevertheless has its own charm, particularly if you can unlock that bonus round. Highly recommended!
