Rock-paper-scissors is a popular two-person hand game.

The game is often used as a selection method in a similar way to coin flipping, drawing straws, or throwing dice to randomly select a person for some purpose. However, unlike truly random selections, it can be played with skill if the game extends over many sessions, as a player can often recognize and exploit the non-random behavior of an opponent.

The players both count aloud to three, or speak the name of the game (e.g. "Rock! Paper! Scissors!" or "Ro! Cham! Beau!"), each time raising one hand in a fist and swinging it down on the count. On the third count (saying "scissors!" or "Beau!" ), the players change their hands into one of three gestures, which they then "throw" by extending it towards their opponent. A variation on this version (played in the United States) involves a fourth count—"SHOOT"—before players throw their gesture.

The objective is to select a gesture which defeats that of the opponent. Gestures are resolved as follows:

- Rock blunts or crushes scissors; rock wins.
- Paper covers or captures rock; paper wins.
- Scissors cuts paper; scissors wins.
