Challenge Balancing for Personalised Game Spaces Bakkes, S.C.J.; Whiteson, S.A.; Li, G.; Viniuc, G.V.; Charitos, E.; Heijne, N.; Swellengrebel, A. Abstract-In this paper we propose an approach for personalising the space in which a game is played (i.e., levels) -to the end of tailoring the experienced challenge to the individual user during actual play of the game. Our approach specifically considers two design challenges, namely implicit user feedback and high risk of user abandonment. We

User studies that validate the approach to online game personalisation in the actual video game INFINITE MARIO BROS. indicate that it provides an effective basis for automatically balancing the game's challenge level to the individual human player.
