Rock–paper–scissors (also known as paper, scissors, stone or other variants) is a hand game usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand. These shapes are "rock" (a closed fist), "paper" (a flat hand), and "scissors" (a fist with the index and middle fingers extended, forming a V).

Rock crushes scissors.
Scissors cuts paper.
Paper covers rock.

Some bacteria also exhibit a rock-paper-scissors dynamic when they engage in antibiotic production.
