Enter the lab to create reactions and riches in Dr. Reactive Mega Drop by SG Digital. Collect five or more symbols to earn cluster wins. Winning clusters disappear, starting a cascade that grants a chance at even greater gains, including stackable wild multipliers that can award up to 1,000x the player’s stake.

Fill the Free Fall meter to earn up to 15 bonus rounds. Lucky players can win one of the three Mega Drop jackpots up for grabs at any time.

What makes Dr. Reactive Mega Drop slot great

The best features in Dr. Reactive Mega Drop include:

  • Cascading reels: Pay symbols in winning combinations disappear, causing new symbols to fall in their place until no more wins occur.
  • Reactive symbols: The atom symbol creates special reactions that boost win potential.
  • Progressive jackpots: There are three unique progressive jackpot drops up for grabs.

How Dr. Reactive Mega Drop slot could improve

This slot also has a few drawbacks:

How to play Dr. Reactive Mega Drop slot online

Instead of conventional reels and pay-lines, Dr. Reactive Mega Drop features an 8×8 grid layout with cluster pays. Use the plus and minus buttons to adjust your total bet value. Click the spin button in the bottom-center of your screen to play, and wait for the machine to fill with symbols.

When adjacent to DNA and lightning symbols, the atom symbol reacts to create additional cascades. With the exception of wilds, a DNA reaction clears all symbols in the column and row that contain the DNA symbol, and each DNA reaction awards 1x the total bet. A lightning reaction clears the grid of the lowest paying symbols (green, red, purple, and orange beakers).

The demo version on this page is free to play, and you can refresh the page to play again with a restored credit balance. For real slots, create an account with a reputable online casino, such as BetMGM or Caesars Casino. Members can take advantage of a variety of weekly and monthly promotional offers, including instant cash prizes and no-deposit bonuses. The latest bonus offers at the top casinos are linked below:

Bonus and jackpots for Dr. Reactive Mega Drop (Rating of 4/5)

This game has several bonuses and jackpots. Some features are present during the main game but altered during bonus play.

Free Falls

The Free Falls meter has seven markers and fills one by one for each winning combination, including DNA and lightning reactions. If the meter reaches five or six in a single round, 10 Free Falls are awarded; if it reaches seven or more, 15 Free Falls are earned. The meter resets after each spin.

During the Free Falls bonus, wilds can appear with 2x, 4x, 6x, 8x, or 10x multipliers, and winning wilds remain in the grid instead of exploding. Each time the wild is used in a cascade, its multiplier decreases by two or disappears for the next Free Fall if already at 2x. Any active wilds multiplier decreases by two at the end of the bonus as well.

Filling the meter by five or more during this bonus awards the players five additional Free Falls. The round is played automatically and ends when no more Free Falls remain, or the max win has been achieved.

Mega Drop jackpots

Mega Drop consists of three progressive jackpots: Minor, Major, and Epic. Each spin contributes a portion of the player’s total bet toward the prize values. Each jackpot must reach a certain value before it’s dropped, and they can be awarded on any wager. Higher wagers increase the chances of winning.

Dr. Reactive Mega Drop graphics and visuals (Rating of 3/5)

The visuals in this game aren’t likely to blow anyone’s mind, but they do a good job of selling the lab genius theme. The strange-looking reactor contains the reels and most other important game functions, such as a detailed display of the current round’s winning combinations and their payouts.

An odd design choice is the complete absence of the titular character. “Dr. Reactive” does not appear at any point during the main game or Free Falls. It’d be a small improvement to have such a character tinkering in the background or interacting with the reels somehow.

Dr. Reactive Mega Drop gameplay (Rating of 3/5)

Possibly the biggest drawback of this slot is its slow-paced gameplay. There are no round-to-round options to speed up play, only autoplay settings to help with longer sessions. Because it’s a cluster pay slot without traditional reels, the usual spinning animation is replaced by filling up a machine, and the cascade wins further prolong individual rounds. A turbo spin option would benefit this game more than many others.

Overall rating for Dr. Reactive Mega Drop by SG Digital (Rating of 3/5)

Dr. Reactive Mega Drop is one of SG Digital’s earliest experiments with a grid-based slot, and whether it’s a successful one or not is a matter of taste. It’s an average game in the graphics and gameplay department, but the progressive jackpots can grow to an impressive size. There are lots of special features as well. However, it usually takes bigger clusters to reap the worthwhile non-jackpot prizes.

Overall, we’d give this slot a 3/5 rating. There are slots with higher win potential and better gameplay, but you can still have a decent amount of fun with this game’s many features.
