About Doctor Reactive Mega Drop Slot

Doctor Reactive Mega Drop is a slot with 8 reels and 8 rows. It functions using the cluster pays mechanism. There are multipliers and special power-up symbols. You will be rewarded when 5 or more symbols form a cluster by connecting on adjacent positions. There are various actuators that you can trigger in the game. You will see all kinds of potion vials with different colours landing on the grid.

The slot has high volatility and an RTP of 96.11%. Players can choose a wager from 0.20 to 100 credits for the rounds. Besides cluster pays mechanics, the game offers cascading wins, multipliers up to x1,000 and 2 reaction features. There are also Free Falls and 3 Mega Drop jackpots on offer.

Doctor Reactive Mega Drop Design

The action takes place inside Doctor Reactive’s crazy lab. It looks is very futuristic and is dominated by purple. On the left of the screen stands a complex machine or gadget which represents the playing set. On the bottom, you will see all the necessary buttons. On the left are the Free Falls and the Win Box displays. On the screen, there are lightning bolts, DNA icons, atoms and potions vials in purple, green, red and orange. The soundtrack is unconventional and quirky, suitable to the gameplay. The game looks like a sci-fi cartoon.

Doctor Reactive Mega Drop Gameplay

The symbols in the game are only 6: there are 4 potion vials in purple, green, orange and red. These in clusters of 5 to 15 symbols of one kind give you from 0.05 to 10 times your bet. There are two action symbols, which have higher values. The lightning and DNA icons pay from 0.5 to 50 times your stake for 5 to 15 symbols in clusters. The icon with the ‘W’ is the wild and it substitutes for all paying symbols. The atom is the scatter that triggers the action symbols.

Fans of the grid-type of slots will be happy with the superb recreation of the lab, constant flashes of lightning and animations. Red 7 has made sure that the gameplay is fast-paced and with a lot of potentials to score huge wins.

The main feature in the slot is the cascading symbol mechanic. There are 8 reels, 8 rows and 64 symbols at the start of each spin sequence. Winning symbols explode and free space for new ones to drop in their places. This can start a chain of reaction within one spin. The Win Box on the left displays all wins through the spinning sequence.

Wild symbols can appear during any stage of the game. As usual, they help you form more and better winning combinations. Besides that, the wild uncovers a random multiplier with values of x2, x3, x4, x5, x10 and higher during the free falls. Getting more than one multiplier with the wilds in a combination makes them stacked. They increase their value in the base game when two or more help to form a cluster. The wild multipliers multiply in consecutive order. The maximal multiplier that you can score is the impressive x1,000!

Doctor Reactive Mega Drop Features & Bonuses

If you land the ATOM scatter it interacts with any nearby positioned Lightning or DNA symbol. Then, it triggers the respective feature. If the Atom scatter lands near a DNA symbol, it activates DNA Reaction. All symbols in the column and row next to this DNA symbol explode. Only wild symbols won’t explode. You will be rewarded with a 1x total bet for each winning reaction. New symbols will fall in the missing places to ensure you more chances for wins.

If the Atom scatter lands near a lightning bolt symbol this triggers Lightning Reaction. A low-value symbol will be randomly chosen and all instances of it on the grid will be destroyed. This happens with the help of a lighting strike and frees blank spaces. The new symbols fall to take them and potentially increase your chances for wins.

Between the grid and the Win Box display, you can see attached the Free Falls display. It shows your advance towards triggering the bonus game. The meter increases by one with each winning cascade in one spin sequence. If you are lucky and reach 5 or 6 cascades before the spin ends you will be rewarded with 10 Free Falls. Those who get 7 winning cascades within a spin sequence win 15 Free Falls. These you can re-trigger the way you activated them indefinitely.

During Free Falls, the multipliers of the wilds have values of x2, x4, x6, x8 or x10. Here, unlike in the base game, the multipliers lock on the grid. They only decrease their value by x2 with each winning cascade. Once they reach x2, the wild multipliers disappear from the game.

Doctor Reactive Mega Drop includes 3 progressive jackpots. The Mega Drop Jackpots are must-drop types and these are Minor, Major and Epic. Every player’s 2% of their bet contributes to their increase. You can win them on any spin and playing with any bet size. As a general rule, the higher the stake, the better chances you stand. The tree jackpots will be won before they reach their set thresholds. These are:

  • Minor Mega Drop Jackpot – 1,500 credits
  • Major Mega Drop Jackpot – 20,000 credits
  • Epic Mega Drop Jackpot – 200,000 credits

After one of the jackpots is won, it resets to 25% of its paid value.

The Conclusion

Doctor Reactive Mega Drop is the first grid-type of game by Red 7 Mobile. The developer has made a nice slot with a lot of action going on and speedy reactions. The lighting bolt, DNA and potions are cleverly included in the gameplay. Thanks to being a jackpot game, it can make lucky players very rich. Give the slot a go and if you like it play it for real.
