Dr Reactive Mega Drop Free Spins & Extra Features

This slot game has a lot of features and symbols that will entice seasoned and novice punters alike. It might be confusing to keep track of the bonuses initially, but we're here to help you with just that! Discussed below are the various bonus features and special symbols that will help you get bigger payouts.

  • Wilds: The wilds of Dr Reactive Mega Drop are certainly reactive. Like most traditional slots, Wilds here substitute regular symbols to form winning combinations, but they also award multiplier values to wins and stick around the grid until they can be used. Unusual, is it not?

If the wild is part of the winning combination, it perishes with the cluster but remains during the cascade if unused until the spin finishes. The Wild replaces all symbols except the atom. If the wild replaces the lightning or the DNA symbol, it won't trigger any reaction.

  • Special Reactions Feature: Two reactions take place when special symbols land next to each other. They remove either the lowest paying symbols or clear any random symbols for newer symbols to land.

The triggering symbol for these reactions is the atom. A lightning bolt symbol landing next to an atom will result in a lightning reaction, where all lower paying symbols will get from the board.

The second reaction triggers when the atom lands next to a DNA symbol. The reaction that triggers will remove all the symbols from the same row and column of the DNA symbol.

All symbols can be replaced or removed except the Wild. This reaction also awards a 1x multiplier value to the total bet.

  • Free Falls Free Spins Feature: The free spins feature in Dr Reactive Mega Drop is called the Free Falls feature. During the base game, consecutive cascades are collected into the free falls meter to the left of the slot. Reaching a minimum of 5 or 6 cascades in a single spin will trigger the free falls feature and award 10 free spins. If you're in your prime and land a fantastic 7 cascades or more consecutively, you'll win 15 more free spins.

Keep in mind; these cascades need to be consecutive and not simultaneous. Any simultaneous cascades that happen will only add a single point to the meter.

During the free falls feature, landing 5 or more consecutive cascades will award 10 or more free spins until no more cascades occur.

  • Dr Reactive Mega Drop Progressive Jackpots: Like all Mega Drop slots, this slot also has a progressive jackpot feature that pays up to £1500 for Minor, £20,000 for Major and a colossal £200,000 for the Epic jackpot. These can be triggered randomly during any spin, and every spin contributes a portion of your total bet towards the jackpot.

How is Dr Reactive Mega Drop played online?

Dr Reactive Mega Drop has an 8 x 8 reel grid and is based on cluster pay mechanics. Land 5 or more of the unique matching symbols next to each other to trigger cascades and land more winning combinations. The bet spread is a versatile £0.20 to £100. All symbols fall into the 8 x 8 grid on a spin. Any clusters formed fizzle and disappear after awarding a win. The rest of the grid symbols fall into their place, including new symbols, like a cascade, to form new winning combinations. The cascading action goes on until no new wins form.

The win box to the left keeps track of all winning combos in a single spin. The free falls meter to the right adds up all the winning cascades to tally up the count.

Take a look at the steps to start playing the game:

  • Once you register, you’ll go to the slot’s game page.
  • Set your bet to the bottom right of the slot, choose between 20p and £100 to determine your total bet. The higher your total bet, the more chances you’ll have to land the jackpot.
  • To the left of the spin button is the settings button or the (?). Click it to get more info about the symbols payout, game rules and special features.
  • Located between the (?) button and the spin is the Autoplay feature You can use it if you want to play a hands-free game.
  • The spin button is the green one, and you can begin playing once you click it.
  • The DNA is the highest paying symbol and is a triggering symbol too. Land more than 15 of these in a cluster and win 100 coins in one go. The Wilds multiplier can go as high as 1000x in the free falls feature.

Storyline, Themes & Symbols

The theme isn't anything spectacular; the graphics are satisfactory enough. There's so much at play in this game that you won't end up noticing the look after you start spinning. The laboratory reminded us of Dexter's laboratory, albeit a bit more serious and daunting with its deep purple colour and the eccentric Dr Reactive dropping in a few times.

The symbols are all very predictable; test tubes and multi-shaped beakers filled halfway with liquid that looks almost radioactive. The symbols fit like a glove; the only thing that stands out are the special symbols; the DNA, the atom and the lightning bolt. The music is not noticeable enough and only comes centre stage when the cascade happens, or the free falls are triggered.

The coin values of these symbols in minimum and maximum symbol clusters are:

Symbols 5 in a cluster 15+ in a cluster.
DNA 2.00 100.00
Lightning 1.00 80.00
Orange Beaker 0.20 20.00
Pink Beaker 0.20 20.00
Purple Beaker 0.10 15.00
Green Test Tube 0.10 15.00
