Othello in an urban space:A trial of doing “Othello ®” game in human scale. Each of participant plays a role of a piece of the game. Unlike we do the game on board and play by two players, there is no center of decision. All the strategy of the game is audible by the opponents. Even you may be in opponents in next turn. Thus players/participants try to adopt/evolve the rule of the game to fit to the situation. The battle field turned to be a field of making agreements to continue and enjoy the game. In the end, the game questions what was the purpose of the game.
