Flux Slot Review

Flux is a colourful video slot from Thunderkick. It has 5 reels and 15 paylines. The look is bold, bright and a little strange, in a good way.

Thunderkick describes the setting as a river of crystals. The river flows through the Thunderverse, its name for the world around its games. Energy seems to radiate from every shape on the reels.

Our earlier page covered this slot in detail. We have rechecked it against Thunderkick’s own game page. Where the studio page is silent, we say so.

Quick answer: Flux is a 5 reel, 15 payline slot with an RTP of 96.2%, according to Thunderkick. It offers rows of stacked wilds and three types of bonus game. The studio labels a figure of 2562 as ‘Max exposure’, without specifying the unit. The release date and bet range are not stated.

Flux at a Glance

Developer Thunderkick
Layout 5 reels and 15 paylines
RTP 96.2%, as listed on the game page
Main feature Massive rows of stacked wilds
Bonus games Three types, per Thunderkick
Theme A river of crystals in the Thunderverse
Volatility 33,58 as displayed by Thunderkick; the scale is not explained
Release date and bet range Not stated on the game page

Theme and Look

Flux feels more like an art piece than a classic slot. Floating shapes slowly spin in a glowing space. Triangular shards of light drift past as you play.

Thunderkick is known for this kind of design. Its games often use hand made art and playful sound. Our guide to Jungle Books shows a very different style, so the contrast is clear.

According to our earlier review, the symbols are coloured shapes in blue, orange, purple, green, pink, red and yellow. Special letters mark the wild and the bonus symbols. We could not check this list on the studio page.

Stacked Wilds

Thunderkick highlights the stacked wilds as the key feature. A stacked wild can fill an entire reel. That makes a full line far more likely on that spin.

Our earlier review said the wild is a yellow W in a rotating frame. It said the wild replaces any symbol except the bonus symbol. We could not confirm the exact rule from the studio page.

Even so, the idea is easy to grasp. When a tall wild lands on a reel, many lines can win at once. As a result, this is the main way to get a big base game win.

The Three Bonus Games

Thunderkick says Flux has three types of bonus game. The page does not explain the rules in full. Our earlier review gave more detail, and we share it here as background.

According to that review, three or more bonus symbols trigger a choice of three free spins options. The options were called Win Both Ways, 3 Extra Rows, and Win Both Ways with 3 Extra Rows.

  • Win Both Ways: wins pay from right to left as well as left to right. It offered the most spins.
  • 3 Extra Rows: the reels grow taller. It offered fewer spins.
  • Both together: you get both changes. It offered the fewest spins.

For three bonus symbols, the review listed 16, 12 or 8 spins across the three options. It also said four or five symbols double or treble the spins. We cannot confirm these numbers, so check the in-game help.

The choice is the fun part. You trade more spins against a stronger feature. There is no right answer, so go with the style you enjoy.

RTP, Volatility and Max Win

Thunderkick lists the RTP as 96.2%. RTP is the share of stakes a slot returns over a very long time. It does not predict a single session.

Thunderkick displays volatility as 33,58 and a figure of 2562 labelled ‘Max exposure’. It does not explain either scale or unit, so we do not present 2562 as a confirmed stake multiplier. Check the in-game rules for the applicable win cap.

Our earlier review said bets ran from 0.10 to 100.00 per spin. Casinos can set their own limits. Always check the range in the game itself.

Casinos may also offer different RTP versions of the same game. The info panel shows the figure at your casino. See our gambling glossary for plain definitions of these terms.

How a Typical Round Plays Out

A simple example shows how the features fit together. It is only an illustration.

  • First: you set a bet and spin the 5 reels.
  • Next: a stacked wild lands on a reel and fills it.
  • Then: several lines win at once, so your balance rises.
  • After that: bonus symbols land, and you pick a free spins option.
  • Finally: the bonus plays out, with extra rows or two way wins.

Most spins will not go this well. Many pay nothing at all. That is normal for every slot.

Tips for Playing Flux

No tip can change the odds. Still, a few habits help you stay in control.

  • Learn the choice: try the demo to see which free spins option you prefer.
  • Check the RTP: open the info panel before you spin.
  • Set a budget: decide what you can afford first.
  • Watch your pace: stacked wilds can make sessions feel fast.
  • Read the bonus rules: see our guide to casino bonus terms before you accept an offer.

Take breaks, and stop when you reach your limit.

Base Game or Bonus: Where the Value Sits

In Flux, both parts of the game matter. The base game gives you regular chances to land a stacked wild. Each one can turn a quiet spin into a decent win.

The bonus round is where the game can build momentum. With extra rows, more lines can pay at once. With two way wins, the same symbols can pay in both directions.

As a result, a patient player gets two kinds of reward. You enjoy small wins from stacked wilds, and you can still chase a bigger bonus. Neither one is guaranteed, so treat every spin as entertainment.

Choosing Your Stake

Pick a stake that lets you play many spins. Bonus rounds do not arrive on a schedule. A small bet gives you more time to see the features.

Use the demo to learn the pace first, where it is available. Then move to real money only if you enjoy the game. If a session stops being fun, take a break.

It also helps to set a time limit. A phone alarm works well. When it rings, finish your spin and stop.

Who Will Enjoy Flux?

Flux suits players who like unusual art and simple rules. The 15 payline layout is easy to read. The stacked wilds give it a clear hook.

It may not suit players who want a big, famous jackpot. The studio’s ‘Max exposure’ field does not specify a unit. Check the paytable for the applicable win cap.

Fans of bold, offbeat slots may also like Hugo 2 from Play’n GO.
