In tabletop games and video games, game mechanics specify how a game works for the players. Game mechanics include the rules or ludemes that govern and guide player actions, as well as the game's response to them. A rule is an instruction on how to play, while a ludeme is an element of play, such as the L-shaped move of the knight in chess.[1] The interplay of various mechanics determines the game's complexity and how the players interact with the game. All games use game mechanics; however, different theories disagree about their degree of importance to a game. The process and study of game design includes efforts to develop game mechanics that engage players.
Common examples of game mechanics include turn-taking, movement of tokens, set collection, bidding, capture, and spell slots.
