In order to propogate information on the World Year of Physics (WYP) and to promote students' appreciation of the significance of this event, the author devised a riddle about Einstein and implemented it at two high schools in Taiwan, with 95 students which were mainly based on Einstein's publications in 1905. During the game 81% of the students responded in the game, and 64% gave the correct answer: Einstein. According to the responses, the riddle seemed to effectively draw students' interest and attention to the incoming event of the WYP. Based on this study, three implications to physics teaching and learning were given.
