In the German language a game is an activity which is executed only for pleasure and without concious purpose. Today the definition of game comes closer to Adornos' definition by identifying game as an art of form. A game must have components and rules, the components are the hardware while the rules are the software. For example the rules for chess are White starts first. the Queen can move in different direction, the King only once and so on.
