An effective use of a computer makes mathematics classes much more interesting and motivates many students to learn. In elementary geometry we have five significant notions for a triangle; that is, the center of gravity, the incenter, the excenter, the circumcenter and the orthocenter of a triangle. Concerning those five points we have a natural problem. Determine a triangle on the plane with one of the following conditions: (1) Three of those five points lie in a common straight line, (2) A vertex lies on the straight line through two of those five points. In this paper we present a drawing game for a student to find a solution to the above problem with fun, and obtain some results from our various experiments.
