Definition: A ludeme or ‘ludic meme’ is a fundamental unit of play, often equivalent to a ‘rule’ of play; the conceptual equivalent of a material component of a game. A notable characteristic is its mimetic property – that is, its ability and propensity to pass from one game or class of game to another.  David Parlett
