A codeless video game method may include receiving an arbitrary game image previously unknown to the computer system and containing object images, each object image corresponding to a game element of the video game, each game element associated with at least one property, and associating automatically each object image with a respective game element that corresponds thereto by identifying automatically, in the game image, each object image. Then a program of instructions is generated that is executable by the computer system, which defines behavior of game elements in the video game according to the at least one property associated with the game elements. During a playing of the video game, the program of instructions causes each game element to be represented in the display by the object image, which may be substantially identical to the game object images that were input as part of the overall game image.
