THESE are the 4 "elements" of games
https://en.wikipedia.org/wiki/Man,_Play_and_Games
>Agon, or competition. E.g. Chess is an almost purely agonistic game. In this form of play, the players have equal chances but the winner succeeds because of "a single quality (speed, endurance, strength, memory, skill, ingenuity, etc.), exercised, within defined limits and without outside assistance."[3] Agon prioritizes skill, work, and professionalization.[3]
>Alea, or chance. In contrast to agon, games of alea depend on chance and fortune.[3] Alea negates skill and highlights "a surrender to destiny".[3]
>Mimicry, or mimesis, or role playing.
>Ilinx (Greek for "whirlpool"), which Caillois describes as "voluptuous panic"[4] in the sense of altering perception by experiencing a strong emotion (panic, fear, ecstasy) the stronger the emotion is, the stronger the sense of excitement and fun becomes. E.g. bungee jumping or Caillois' example of children spinning in a circle until they become dizzy.[4]
