Visual attention plays a critical role in game playing. A better understanding of the allocation of visual attention can benefit the design of game scenarios. In this paper we propose to design games in different difficulty levels based on the estimation of attention. We use eye movement information in an analysis of attention. Eye fixation and pursuit conditions are considered separately. We find that the image complexity at eye fixation points and the relative position between pursuit direction and disturbance during pursuit eye movements are significant for attention allocation. This result is applied to the design of an interactive 2D game having two difficulty levels. Player response speeds and scores are compared for each difficulty level of the game.
