Introduction

When you enter Dr Reactive’s Laboratory, you will be struck by the interesting game layout and the many colored cork-stoppered bottles and test tubes.

The symbols that appear in Dr Reactive’s Laboratory are vials and test tubes, which are corked and filled with many colored liquids - orange, green, purple and red. There is a DNA symbol showing the double helix of a DNA structure, a yellow lightning bolt against a blue circular background, and an atom symbol with moving electrons as a scatter. There is also a glowing W that acts as the wild.

Bonus features abound in the lab, including free falls, wilds, scatters, cascading reels and three tiers of a Mega Drop jackpot. Further information on the bonus features is available later in this review.

Theme, graphics & soundtrack

The theme of this game is an oldie but goodie. Since Frankenstein and his monster, we have been fascinated by the idea of a mad scientist grafting away in his secret lab, playing with all things unnatural and pushing the boundaries of reality. It can be an exciting and strange phenomenon, experimenting with different liquids, gases and solids to create and change the world around us. Dr Reactive has a colorful laboratory full of mystery and machines of unknown purpose to outsiders.

The graphics are fun and bubbly, of great quality and aesthetically satisfying. Dr Reactive's Laboratory has a soundtrack that fits the theme, namely an electronica soundtrack with a catchy beat. The music churns in the background, amplifying when you hit spin.

Dr Reactive’s Laboratory RTP & volatility

The game offers two different RTP (return to player) percentages - with the Mega Drop jackpot, Dr Reactive offers 96.11 per cent; without the jackpot, it sits at 94.11 per cent. The volatility is medium-high.

How to play Dr Reactive’s Laboratory

Begin your foray into Dr Reactive's Laboratory by following a few simple steps:

1. As the game loads, you will see the rules for the game's cascading symbols, lightning reactions and DNA reactions. Tap anywhere to continue once loaded.

2. When you see the laboratory, click on the double arrow button on the right-hand side to open the menu. Click the question mark to familiarize yourself with the game rules, payouts, grid game rules, wild symbols, atom symbol, DNA reaction, lightning reaction, free falls, Mega Drop and legal information.

3. You can go back into the double arrow menu and click on the 1 button. Here, you can select your betting stake from 0.20 to 100.00.

4. Going into the double arrow menu once again, you can choose to use the autospin function and select 5, 25, 50 or 100 spins. Dr Reactive gives you the option of choosing when to stop the autospins feature, meaning you can be more aware of your betting limits - set a level to ‘stop when lost more than...' and 'stop on a single win over…'.

5. Once you are set up, press the spin button to start the cascading reels. When at least five matching symbols land adjacent to each other, you will receive a prize. The reels will continue to spin until you have exhausted the wins in each spin.

Dr Reactive's Laboratory bonus features

There are various exciting bonus features in Dr Reactive’s Laboratory:

- Free falls

The free fall feature is measured by the free falls meter to the bottom left of the grid. New symbols will fall into the grid after lightning reactions, winning combinations or DNA reactions and will each increase the meter by one. Once the meter gets to either five or seven, you will be rewarded with 10 or 15 free falls.

- Wild symbols

When the atom symbol lands next to a lightning bolt or a DNA symbol, it triggers a reaction. A DNA reaction forces all the symbols - minus the wilds - in the row and column to explode, to be replaced by new symbols. The lightning reaction causes both the atom and the lightning symbols to explode and lightning bolts flash across the grid, replacing lower-paying symbols with new ones.

- Mega Drop

With the Mega Drop progressive jackpot, each of the three jackpots has to be won so that the maximum payout size can be reached. These are 1,500 credits (minor), 20,000 credits (major) and 200,000 credits (epic).
