Our review will cover tips and tricks for optimal gameplay, and take a look at the graphics, bonuses, and features you can expect when spinning the reels on this exhilarating online slot game.
SG Digital slots partnered with WMS and Red7 to bring Dr Reactive to your screen, with one little surprise: you’re the mad scientist and you’ll be cooking up some chemical cocktails in the hopes of winning big!
Dr Reactive can be played as a standalone slot, with an RTP (return to player) of 94.11%, or as part of the Mega Drop progressive jackpot network, with an RTP of 96.11%. The game features a unique 8×8 grid with 64 colorful symbols. The grid doesn’t feature traditional paylines. Instead, you need to land a cluster of 5 or more matching symbols, either vertically or horizontally, to create a winning combination. The more symbols that form part of your cluster, the larger the potential payout.
This casino slot game also uses a cascading reels mechanic, so after a cluster is formed, the winning symbols disappear from the screen and new symbols drop down from the top of the screen, creating chain reactions and giving you more opportunities to score on a single spin.
The medium-to-high volatility means that there are moments when plenty of winning symbols and stacks of multipliers chain together to increase the payouts and that these moments may be less frequent, but the rewards are plenty satisfying.
How to play
- Once you’ve selected this slot game from your online casino of choice, the game window will open on a page of rules. Tap anywhere to continue once loaded.
- Start off by reviewing the paytable, which you can get to by selecting the green “?” below the game grid. Familiarise yourself with the rules, payouts, features, and Mega Drop information.
- Set your bet limit (choose from 0.20 to 100 credits) by selecting the green “-” or “+” buttons in the right corner of the banner below the grid.
- If you’ll be playing with the autospin function, select the button just left of the Spin button, and choose between 10 and 200 spins, as well as your win and loss limits.
- Once your setup is complete, you can get spinning by selecting the Spin button in the center of the banner below the grid. The symbols will start tumbling onto the grid (be sure to have the sound volume up – the audio effects are super entertaining) and when 5 or more matching symbols form a cluster, the winning amount will be deposited to your “WIN” balance at the bottom of the screen.
- The potions you score during a winning cluster will accumulate in the WIN BOX to the left of the grid.
The reels are set in a purple cartoon-style laboratory and a catchy electronica soundtrack plays while you spin the reels. The animations and sound effects make every spin exciting, and the potions you collect along the way really get you invested in the game! Red7 went out of their way to create a visually appealing game with plenty of fun features and animations to keep you entertained throughout.
Symbols fall onto the reels with a satisfying clink and include potions in a variety of colors and different shaped test tubes and vials, a lightning bolt against a blue background, a strand of DNA, and an atom symbol with moving electrons that acts as the scatter. The wild appears as a radioactive “W”. Each time a cluster is formed, a chemical explosion takes place, followed by the “cha-ching” sound effect of the coins making their way into your bank account.
The animations and sound effects make the game really fun and exciting.
The free falls meter to the left of the grid builds up in increments of 1 with each winning combination or DNA or LIGHTNING reaction. When the meter reaches 5 or 7, 10 or 15 free falls will be awarded respectively. The meter resets after every spin.
As in all slot games, the wild can substitute for any symbol (except for the scatter) to help form winning combinations. The wild in Dr Reactive may also have a multiplier of up to 5x attached to it for a great little boost to your potential win.
During the free fall round, the wild can come with multipliers of up to 10x and will remain in place while the rest of the symbols are replaced during wins to increase the potential of landing another winning cluster.
Atom Scatter Explosions
The atom symbol is the scatter and as in any lab, it comes with a chemical reaction! In this case, the reaction happens when the atom symbol lands next to either the DNA symbol or the lightning bolt.
DNA Reaction Feature – When the atom reacts to the DNA symbol, all the symbols (except for wilds) in the column and rows of the DNA symbol will explode, and a cascade will follow.
Lightning Reaction Feature – All the lowest paying symbols will explode, creating a cascade and the possibility of a winning cluster.
Bonuses and jackpots
The Mega Drop progressive jackpot consists of three jackpots – the minor, major, and epic jackpots. A portion of the player’s total is contributed to the progressive jackpot on each spin. The jackpot can be awarded on any wager, however, each of the three jackpots must be won before the maximum payout size can be achieved. The minor jackpot comes in at 1,500 credits, the major at 20,000 credits, and the epic jackpot at 200,000 credits.
