How to Play

Doctor Reactive Mega Drop is a slot with 8 reels and 8 rows. The action takes place inside Doctor Reactive’s lab and players can choose a wager from 0.20 to 100 credits for the rounds. After you’ve selected a wager, the spin will then be initiated and the symbols will fall into an 8 x 8 grid.

Awards are shown per winning combination for each symbol type.

How to Win

To win, you must get a winning combination of at least five symbols of the same type positioned adjacently to each other. Any winning combinations will explode and disappear leaving empty spaces in the grid – eventually being replaced by symbols in the positions above.

Any additional winning combinations after a cascade will be evaluated and trigger another cascade until no further wins are awarded.

Game Rules


To make the most of this slot, you need to take note of the special features. These include:


Wild symbol

The WILD symbol substitutes for all other symbols except the ATOM symbol. In the base game, the WILD symbol contains a multiplier between 1x and 5x.


Atom symbol

The ATOM symbol reacts with the LIGHTNING symbol and DNA symbol to cause further cascades.


Free falls

When symbols fall into the grid, the FREE FALLS meter is incremented by 1. If this meter reaches 5 or 6, 10 FREE FALLS are awarded. 15 will be awarded when the meter reaches 7, with them being played automatically.


Mega drop

Mega Drop consists of three Progressive Jackpots, which are made up of Minor, Major and Epic jackpots. The maximum payouts for these are:


Jackpot Max award
EPIC £15,000.00
MAJOR £5,000.00
MINOR £1,500.00


On each spin, a percentage of the player’s total bet will be contributed towards the progressive jackpots. When a Progressive jackpot is awarded, it is then reset at approximately 25% of the value paid out. You cannot win multiple jackpots with one wager, so the jackpot with the higher maximum drop value will be awarded.
