Slot Details

Doctor Reactive Mega Drop is an 8×8 grid slot with cluster pays, multipliers and power-up symbols. Wins are awarded for five or more matching symbols connecting in adjacent positions. You can cook up potions on desktop or mobile from 0.20 to 100 credits per spin. The game medium to high volatility with an RTP of 96.11%.

A futuristic science lab is naturally the fitting visual for this game and could come straight from a sci-fi cartoon. The game window is connected with various displays and actuators that will be triggered during the gameplay. A range of potions vials in different colours dominate the grid while a quirky soundtrack keeps things interesting throughout a session.

There are only six pay symbols, starting with four potion vials in green, purple, red and orange colours. Clusters of 5 to 15+ symbols will award 0.05x to 10x your bet. They are followed by to action symbols – a lightning and a DNA icon, paying 0.5x to 50x your stake for clusters of 5 to 15+ symbols.

An icon marked with ‘W’ is the wild, substituting for all regular pay symbols, while an atom acts as the scatter symbol that will trigger the action symbols.

Doctor Reactive Mega Drop Slot Features

If you are a fan of grid slots, then this one could end up rather high on your favourites list. It is a superb depiction on how things would unfold in a lab of a mad scientist with constant lightning arcs and other animations. Red 7 spiked the gameplay accordingly that allows it to generally have a fast-paced flow but also brings in the potential to score big wins.

At the core is the cascading symbol mechanic which sees 64 symbols dropping at the start of a spin onto the 8×8 grid. Any winning combinations will explode to make space for new symbols to drop in place and potentially start a chain of winners within the same spin sequence. It all comes to an end once no new wins occur after a cascade. Keep an eye on the Win Box to the left as it will display all wins throughout a spin sequence.

Wild symbols can drop in at any time in a spin sequence to help you form winning clusters. Not only that but it will also unveil a multiplier which can be between x1 and x5 in the base game and between x2 and x10 in the free falls feature. More than one multiplier in a combo are stacked and the win value multiplied in consecutive order by each multiplier. The maximum multiplier is x1,000.

Next in line is the ATOM scatter symbol that can also land on the grid at any time. When it does it will interact with any adjacent DNA or Lightning symbol, that is after any potential wins are paid.

• DNA Reaction: The symbols in the row and column with the adjacent DNA symbol explode, except any Wild symbol. Plus, the game awards a coin win of 1x the total bet per reaction. New symbols fall then into place to potentially create more winners.
• Lightning Reaction: One low-value symbol is randomly chosen and all instances will be destroyed by a lightning strike, creating empty spaces for new symbols to drop into place, again creating potentially more winning combos.

Keep an eye on the Free Falls display next to the Win Box as it is your path to trigger the bonus round. The meter will increase by one for each winning cascade within one spin sequence. Reach five or six before the end of a spin and you’ll get 10 Free Falls while reaching seven or more will award 15 Free Falls, which can be indefinitely retriggered in the same fashion.

During the feature, the multipliers on the Wild symbols are boosted to x2, x4, x6, x6, x8 or x10. They will stay on the grid between cascades but the multiplier will decrease each time they are part of a combo. Any unused wilds will also stay on the grid but the displayed multiplier will reduce with each cascade until it reaches x2 after which it will disappear. The round ends when you run out of Free Falls.

Mega Drop Jackpots are a new type of must-drop progressive jackpots – Minor, Major and Epic – with 2% of each bet contributing to them. They can be won on any spin and at any bet size, although the chances to trigger one of them is relative to the bet size. The jackpots will trigger before they reach the set thresholds which are for Minor – 1,500 credits, Major – 20,000 credits and Epic – 200,000 credits. Once won, the respective jackpot will reset to 25% of the paid value.

Final Verdict

Well, here is the first full grid game from Red 7 Mobile and it is not a bad first effort. The gameplay is fast-paced and intense thanks to the frequent lightning animations and sounds. The win potential, other than the jackpots, is medium only but then it is geared towards jackpots chasers. The maximum amount for the Epic jackpot is surely enticing enough to give it a few spins.
