Dr Reactive's Laboratory: Slot Review

Dr Reactive’s Laboratory

Dr Reactive’s Laboratory also known as Doctor Reactive Mega Drop is a slot developed by RED7 that will introduce you to a laboratory full of prizes. Do you have the soul of an alchemist? Start playing Dr Reactives Laboratory for free here at SlotJava!

Dr Reactives Laboratory numbers

The RTP in this slot is 96.11%, a discrete figure, but not excessively racana. The game is developed on the basis of 8 reels with 8 heights, all of them active without the need for bonuses or any other function to appear.

There are actually no pay lines. In this game, to obtain prizes the symbols have to fall together, regardless of whether it is above, below, to the left or to the right.

The minimum bet is 20 cents and the maximum of 100 euros.

Take the prizes in the DNA - Special functions

In this slot you will be able to feel the chemistry of the prizes. When five or more symbols come together, you are awarded a prize and the symbols explode to drop new ones. Of course, if new winning combinations are generated in this new symbol drop, you will also collect them.

The wild symbol substitutes for any symbol except the atom and can have a multiplier ranging from one to five. If there are multiple wilds in a winning combination, the amount won will be multiplied by each multiplier up to a maximum of x1000. Once the wild is used in a winning combination, it will explode and disappear. If it is not used, but there has been some winning combination, so more symbols are going to fall, it will stay there.

The atom symbol reacts with the lightning bolt and the DNA. When combined with DNA, they explode the row and column and give a prize equal to your bet, as well as dropping new symbols. When combined with the lightning bolt, a lower paying symbol type will be randomly selected and all those of that type will disappear, making room for a new symbol drop.

On the left, you will see a liquid meter. This meter fills up as symbols fall as a result of a winning combination on a roll. If filled to the appropriate levels, you will receive 10-15 Free Spins. During the free spins, the multiplier of the wild symbol can go from 2 to 10.

The prizes

The most interesting prizes are those of the progressive jackpot that with this developer can be obtained in the slots called Mega Drop. These prizes are awarded randomly, but the higher the stake, the more likely it is to get them.

There are three jackpots: Minor, with a maximum of € 1,500, Major, with a maximum of € 20,000, and Epic, with a maximum of € 200,000.

Besides, we also have the possibility of multiplying the bet by 1000 with the multipliers.

As for the base game, 15 DNA symbols multiply your bet by 50 and 15 rays times 40. Therefore, the potential for strong wins is in the multipliers of the wilds, not so much in the base game.

The design - Welcome to the laboratory

The The design of this game has a comic aesthetic in which we play on a somewhat incomprehensible machine with a laboratory in the background. The symbols are the different typical containers of a laboratory.

The music is pleasant and it is animated by the prizes, in our opinion it contributes a lot to the game giving it dynamism.


It is an original slot that avoids the classic five reels and the paylines scheme. The variance is medium, so there can be bad streaks and low prizes or good and high prizes. Although this is a no-brainer when it comes to slots, your experience with this game will depend a lot on your luck. It is not one of those games that are entertaining even if you lose.
