Dr Rock & the Riff Reactor Slot Information

Dr Rock may at first seem like a pretty creepy guy. We’re invited to his lab, where he has created the Riff Reactor, a huge machine full of speakers and amplifiers. In the middle of it stand the five reels, and each of them has a multiplier above them, starting at 1X on each spin in the base game. A monkey with a guitar sits beside the reels in this dark room full of white smoke. To make a win on the doctor’s reels, you need to land 3 or more symbols of the same type on adjacent reels, starting on the first reel to the left. The game is available on mobile phones, notepads, and desktop computers.

The lower-paying symbols in this high voltage place are 10, J, Q, K, and A. Landing a 5-of-a-kind win with them awards between 0.25X and 0.5X the bet. The higher-paying symbols are electric guitar, drum set, and Dr Rock himself. These three symbols will get you between 1.5X and 3X the bet for a win containing 5 symbols. The Wild Symbol substitutes all mentioned symbols but not the Scatter. It’s also the best-paying one, awarding 4X the bet for a 5-of-a-kind win.

Dr Rock & the Riff Reactor Slot Features

You can win up to 100,000X the bet.

What features are available in the slot Dr Rock & the Riff Reactor?

The features are Wild Symbol, Cascading Ways, Power Chords, Overdrive Coils, High Voltage Free Spins, and Bonus Buy.

Wild Symbol

The Wild Symbol substitutes all regular symbols in making wins, but not the Scatter Symbol.

Cascading Ways

Once a winning combination is achieved, the symbols vanish, making way for new ones to drop down and fill the vacant positions. The cascades will keep rolling until no more winning ways appear.

Power Chords

During each spin, a random symbol on every reel becomes enframed with a golden frame. If the winning combination matches the symbols within these golden frames, the respective multipliers above each reel – the so-called Overdrive Coils – increase by one.

Overdrive Coils

These multipliers apply to all winning combinations. Each spin starts with base multipliers of 1X, which is upgraded in the Power Chords during cascades. The multipliers are multiplied by each other. For example, if you have a 2X and a 3X multiplier, your win will be multiplied by 6.

High Voltage Free Spins

To trigger this thrilling feature, keep an eye out for 3 Scatters appearing anywhere on the field, granting you 8 spins. For each additional Scatter, you get 2 extra Free Spins. During the feature, 2 Scatters reward 2 spins, and you get an extra spin for every Scatter above 2.

What’s even more electrifying is that the Overdrive Coils’ multipliers are not reset in Free Spins and carry over from the base game, maximizing your winning potential.

Bonus Buy

If you can’t wait to dive into the Free Spins action, hit the Buy Bonus button! This allows you to activate the Free Spins instantly. You can buy the regular Free Spins for 100X the bet or the Super High Voltage Free Spins for 300X the bet, starting with a 2X multiplier.
