 To pool the talent of individual game designers, Enix sponsored a national programming contest.Three-hundred programs were entered into the contest, and the first prize went to programming prodigy and high school student Koichi Nakamura for his puzzle game, "Door Door".Yuji Horii placed in the finals of the same contest with a computer tennis game; both were subsequently hired by Enix and the rights to "Door Door" became property of Enix.
