How the Game Plays

Dr. Reactive takes players into a high-voltage laboratory where chemical experiments lead to explosive wins. Developed by Light & Wonder, this title utilizes an 8x8 grid instead of traditional paylines. Wins are generated when clusters of five or more matching symbols—such as various colored vials, thunderbolts, and DNA strands—connect horizontally or vertically. A cascading mechanic follows every win, removing successful clusters to allow new symbols to tumble into the empty spaces, potentially creating a chain reaction of multiple wins from a single spin.

Free Falls Explained

The game features a Free Falls bonus, which serves as its version of free spins. This feature is not triggered by a single set of scatters but rather by consecutive cascades. Filling the meter with five consecutive wins awards 10 Free Falls, while seven cascades in a single sequence grant 15 Free Falls. During this round, the value of Wild multipliers is significantly enhanced, increasing the potential for high-value combinations.

Chemical Reactions & Mega Drop

Special gameplay modifiers are triggered by symbol combinations. The DNA Reaction occurs when a DNA symbol lands adjacent to an Atom scatter, replacing lower-value symbols with higher-paying ones. The Lightning Reaction involves a Lightning symbol and an Atom, which clears all low-value symbols from the grid entirely. Furthermore, the game is part of the Mega Drop network, offering three progressive jackpots—Minor, Major, and Epic—that can be triggered randomly on any spin.
