Dr. Rock & The Riff Reactor: Slot Review and Free Play Demo

Dr. Rock & The Riff Reactor Review

TrueLab Games has always been one of the most interesting and creative studios out there, and once again the company comes up with quite an intriguing game called Dr. Rock & The Riff Reactor. As the title already hints, it has a deep musical theme, but what’s most compelling here is the gameplay, packed with an array of lucrative features, providing a colossal winning potential.

Visually, Dr. Rock & The Riff Reactor is an absolute masterpiece. TrueLab Games has put plenty of effort into the graphics, animations, and especially sounds of the game, which deserve a special mention here. A classy rock soundtrack plays whilst you spin the reels, which picks up the tempo during bonus features, and you hear powerful guitar riffs when you hit wins, creating a fantastic and highly immersive atmosphere.

Dr. Rock & The Riff Reactor Slot - Reels Screen

On the 5x3 reels, we see 8 regular symbols, which create winning combinations along 243 paylines. At the lower end of the paytable are 10-A royals, and then three high-paying symbols, including guitars, drums, and Dr. Rock himself, whose character was obviously inspired by Dr. Emmett Brown from the legendary Back to the Future franchise. Plus, there are Wild symbols included that help you to achieve wins by substituting for any of the regulars.

You need to land at least 3 of the same symbols adjacently on the reels starting from the leftmost to achieve a win, and 5-of-a-kind wins are worth from 0.25x to 1x the bet. Meanwhile, Wilds are worth the biggest, paying 4x the bet for combinations of five. These are pretty low values indeed, but once the features step in, potential payouts improve drastically. We’ll cover that shortly in the features section below.

As for math, the Dr. Rock & The Riff Reactor slot has a decent balance between the risk involved and possible achievable wins. The volatility is high and might be brutal for some of the players, but rewards up to 50,000x the bet are definitely worth the effort.

The default RTP is decent at 96.03%, which is a whisker above average, but you should keep in mind that the game is supplied in several different versions, which means casino operators can offer different payback values that can be higher or lower than the standard. 98% is the highest but is less likely to be found. The other values are significantly lower, namely 95.05%, 92.11%, and even 89.06%. Thus, be sure to look through the rules before depositing.

Dr. Rock & The Riff Reactor Slot Features

Whenever a win is scored in the Dr. Rock & The Riff Reactor slot, the Cascading Wins feature comes into play. All symbols involved in a win get removed from the reels, and then new ones tumble down from above to fill empty spaces. The process continues until no more winning combinations are made.

That is linked to the progressive multiplier feature, increasing the payouts exponentially with each cascade during the base game. Above each reel, you can Overdrive Coils which display multiplier values, starting from 1x. On each spin, one random symbol on each reel gets framed with Power Chords, and if such a symbol takes part in a win, the Coil value above is increased by +1x. Then, the values shown on the Overdrive Coils are applied to all winning combinations of the respective length. Most importantly, they don’t just sum up but multiply each other also. For instance, if the reels have multipliers of 5x, 3x, 2x, 1x, and 2x, the total multiplier value would make 60x, as shown in the screenshot below.

Dr. Rock & The Riff Reactor Slot - Free Spins

Most of the payouts in the Dr. Rock & The Riff Reactor slot come from the High Voltage Free Spins feature, which is triggered when at least 3 Scatters show up on the reels simultaneously during the base game. Landing 3 Scatter symbols awards 8 spins, and +2 spins are awarded for each additional triggering symbol. It’s also possible to obtain extra spins while in the bonus - 2 or more Scatters grant +1 free spin for each extra Scatter after the first. Thus, if 2 or 3 Scatters appear, players receive +1 or +3 spins, and so on.

Once activated, the current Overdrive Coils multiplier values are carried over to the bonus. Overall, the feature operates in a similar way to the base game, but a major difference is that multipliers do not reset between the spins and keep growing until the very end of the free spins. Additionally, a random Wild is guaranteed on each spin.

Free Spins can be activated instantly via the Buy Bonus. Two options are available, as follows:

• 100x the bet - triggers a spin with at least 3 guaranteed Scatter symbols that trigger High Voltage Free Spins.
• 300x the bet - triggers a spin with at least 3 guaranteed Scatter symbols that trigger Super High Voltage Free Spins with starting multipliers of 2x.

To conclude, Dr. Rock & The Riff Reactor has a lot for players to offer, and it’s certainly bound to be enjoyed by slotters. It has superb visuals, and the gameplay lurking beneath is equally impressive, packed with cosmic features and incredible potential rewards.
