How to play

Instead of a standard playing field with reels and rows, there will be transparent plastic tubes connected in the shape of an atom. Balls appear in these tubes - these are symbols. To get a win on Orbital-Reels, you need to get from 3 to 6 matching symbols on adjacent positions. There is also a special symbol that triggers the free spins feature and the Twin Win Booster feature can be activated at any time.

After you find yourself in an atomic reactor you need:

  • Click on the settings button in the upper left corner of the screen to view the paytable and rules
  • In the settings, find the flap setting and select the bet from €0.10 to €20
  • Hit the Spin button to make combinations of balls inside the atomic reactor!

Atomic Reactor RTP and Volatility

7 
RTP is 96.19% and volatility is unknown.
It's a pity, but the provider did not give official information about the volatility of the slot machine. After our test session, we can suggest that the risk here is at an average level since winning cascades here are triggered quite often and premium symbols can bring really pleasant payouts. As for the RTP, it is 96.19%, which is higher than the industry average.

Theme

When you load the game, you are transported to an atomic reactor. Several transparent plastic tubes appear in the middle of the screen, interconnected in the form of an atom. As soon as you grow the reels, small balls begin to circulate quickly inside the tubes - these are the symbols of which you have to line up on adjacent reels to get a payout. As you play, music with the barely distinguishable words "atomic reactor" will play, sometimes it can be quite annoying, so it's good that the slot has a mute button.

This slot is very different from what you are used to seeing. The suits of playing cards, ancient Egyptian gods, or precious stones do not appear on the playing field, no, only multi-colored balls are used as symbols - these are сores with the help of which an atomic reactor generates nuclear energy. To make a winning combination, you need to land 3 to 6 identical symbols on adjacent reels.

Any win with regular symbols triggers a cascading reaction, replacing all winning standard symbols with new ones and filling the Win Multiplier Meter to boost any new wins reaction triggers. Having landed 2 simultaneous 3x wins with ordinary symbols, you activate the Twin Win Booster feature.

Overall Rating

7.8
The music theme of the slot is strange and tense, but at least unique. The design is minimalistic but at the same time manages to be interesting due to the unusual Orbital-Reels playing field installed in the atomic reactor. The free spins feature with a 2x multiplier for all wins requires only 4 or more Special Symbols to activate and Twin Win Booster is capable of bringing impressive payouts.
