Mad scientists in movies always act like they’re this close to changing the world, despite half the time being just one spilled beaker away from turning themselves into a glow-in-the-dark ferret. They insist society “isn’t ready” for their inventions, which is usually code for “this thing explodes if you look at it funny.” 

The new Dr. Rock & Frozen Monkey slot from Truelab is what happens when you combine a mad scientist with a rock-and-roll side hustle during the festive season. 

Let’s rock!

The Dr. Rock & Frozen Monkey slot features 243 ways to win across a 5×3 reel grid. It offers you the chance to win up to $400,000 when betting at the $40 a spin maximum. However, thanks to the 10,000x max multiplier, even betting at the $0.20 minimum gives you a shot at some impressive wins. The slot features medium to high volatility and offers an RTP of 96.13%.

Each winning combination will trigger the slot’s cascading reels feature that will remove all the symbols involved in the winning combination, allowing new symbols to fall into the empty spots. This will continue to occur until no new winning combinations are formed.

The slot’s reel multipliers can be found above each reel. They will have a base value x1 and increase through the enframed symbol mechanic. During each spin, one random symbol on every reel is marked. If a winning combination includes an enframed symbol, that specific reel’s multiplier is increased by 1x. 

In the base game, the multiplier values will continue to grow throughout winning cascades and be reset with each new spin. During free spins, the values will continue to grow throughout.

If a winning combination includes a symbol on a reel with a multiplier, the multiplier will be applied to the winning amount. If multiple multipliers are involved, they will first be multiplied together before being applied.

A round of the slot’s free spins is triggered with three or more scatter symbols. Three scatter symbols will award eight free spins, and each additional scatter used to trigger the feature will add two extra spins. The slot’s free spins are retriggerable with two or more scatter symbols. 

During a round of free spins, reel multipliers will continue to grow throughout, and wild symbols will randomly be thrown onto the reels.

In addition to unlocking a round of free spins the old-fashioned way, the slot also gives you the option to purchase a round of free spins outright.

Is the Dr. Rock & Frozen Monkey slot rock and roll enough?

The Dr. Rock & Frozen Monkey slot feels like the kind of Christmas gig where someone plugged the lights and the PA into the same sketchy extension cord, then cranked everything to eleven and walked away. 

The cascading wins and enframed reel multipliers do a lot of heavy lifting here, and when they start chaining together into those big, stupid win sequences, the 10,000x max win suddenly stops feeling theoretical. 

It’s all in all a well-executed Christmas slot. That said, it’s also a shameless Christmas reskin of the Dr Rock & Creepy Monster slot, which counts against it. I give the Dr. Rock & Frozen Monkey slot an eight out of ten.
