Reagents themed slots are essentially science and chemistry-inspired games which feature symbols depicting reagents. A reagent is a special compound or substance which is added to other substances or compounds in order to cause chemical reactions. Reagents are also commonly added to chemistry tests in the case of a chemical reaction occurring.

The term reagent is closely related to the term reactant so these two terms are often used interchangeably. Nonetheless, reactants are substances or compounds which are consumed during a chemical reaction while reagents are generally added to cause a chemical reaction. Using reagents in chemistry is closely related to solvents and catalysts which also have their part in chemical reactions.

Since these games are inspired by chemistry, their symbols are crafted to look like potion bottles, other equipment used in chemistry labs such as chalk tables, radioactive compounds and substances, and other tools. These games also include human characters wearing safety goggles while their backdrops depict underground labs.

Aside from being nicely crafted, reagents themed slots generally feature Free Spins and respins bonuses in addition to bonus symbols including scatters and wilds. Their gaming grids include 5 reels with 10, 20 or 30 paylines. Some games of this kind feature more paylines up to 243 for even more winning opportunities.

Playing regents themed slots also means benefiting from special multiplier symbols which come attached with 2x up to 10x winning multipliers. In some reagents themed slots, players can also be rewarded with instant cash winnings as a part of their mini-bonus modes.
