The game jockey is a new practice between DJing and video gaming. This study underlines the difficulty to hybridize these two creative cultures. Game jockey implies a person, who will mix games during a live performance, by adapting to the players’ feelings. We will present key concepts of the DJ practice and the similarities to the game universe. Based a Jockey – Game – Players triangle, we offer a creation research that tries to evaluate the possible figure of the jockey and the use of game samples. Our triangle model opens on cultural practices that are to invent.
