The invention relates to a humanoid game-playing robot, a method and associated computer programs. In the prior art, there is no humanoid robot which is able to move on its lower limbs, to make gestures, communicate by way of visual and/or audible signals, receive the latter and interpret them in order to deduce appropriate behaviour for participating in a game as host, question poser, question answerer, investigator or moving subject of the game. The hardware, internal-software and programming-software architectures of the robot of the invention make it possible for these functions to be carried out and for new game experiences to be created, in which the frontiers between the virtual world and the real world are moved again.
