Reactor slot review

Reactor bonus features

The Reactor game screen is set against a backdrop of machines and motion. Given the name, it’s probably part some kind of energy-generating mechanism but that’s left to our imagination.

On the low value end of the paytable we can see four colorful crystals in green, yellow, red and purple. Another set of symbols in the same colours appear to be machine parts and are of a higher value. The green and yellow components are the most valuable, rewarding with x20 the initial stake.

This game pays out in both directions so wins are possible from left to right as well as right to left along the 20 built-in paylines.


A ball of electrical energy is the Wild symbol on Reactor. It will replace all other symbols except for the battery and it also pays out fairly generously – up to 25 times the initial bet.

Battery Re-Spins

The battery is a central aspect of this game and the more you land, the better the rewards. One battery appearing on the reels will award one re-spin.

If two show up on the same spin, one re-spin will be awarded with the Swap Symbols feature active. This means that random symbols will be transformed into ones that are of a higher value.

When 3 battery symbols show up, a re-spin is awarded with the Swap Symbols feature activated as well as the Random Wilds feature, which adds, you guessed it, Wilds to the reels at random.

When four batteries appear on the same spin, the player receives a re-spin with the Swap Symbols and Random Wilds features activated and the Mega Wild feature thrown in too. This adds one Mega Wild block, of either 2×2 or 3×3 size, to the reels.

Lucky players landing 5 batteries at once will get one re-spin with all these features active and an additional x10 multiplier applied to any winnings.

Reactor Free Spins

Reactor does not offer free spins but we think the re-spins feature more than makes up for their absence.

Reactor jackpot

The Reactor slot does not include a jackpot feature.


Reactor has an RTP of 96.02% and a high variance. The Return to Player falls within the average range and the high volatility means that players will likely keep a fairly stable bankroll, buoyed by sizeable though irregular wins.

Reactor Mobile

Take this powerhouse of a slot with you everywhere you go! Reactor is fully mobile compatible and will perform as it should on iPhone, iPad and Android devices.
