Also interesting from the perspective of game classifications is the one from Roger Caillois from 1958's "Les Jeux et les Hommes" into Agon (competition), Alea(chance), Mimicry(simulation), Ilinx(vertigo), as well as ludos(game(ing)) and paida(toy(ing)). Of course there are others, but i think it's inspiring to think about what can be a game or is part of "playing". For example i think it's funny how many people say the are not playing while they do gardening/skiing or dancing in their free time. here's a nice image of it with samples: https://community.trustinplay.eu/t/concept-alea-agon-mimicry-ilinx-classification-of-play/862 https://community.trustinplay.eu/t/concept-alea-agon-mimicry... To understand games it's also important to think about who knows what (and what's a secret). Some knowledge of the game state is only available to one player (for example to the player hiding the stones in op example). Other gamestate knowledge is available to all. Some knowledge is not given to anybody, but fixed nevertheless (hidden cards in a stack). > The Art of Game Design - A Book of Lenses - Jesse Schell: p168 . I mention this because it's equally random to throwing a dice for the girl who chooses the hand with the more stones. While it's not random from the perspective of the ones hiding the stones.
