In this study, the smart game based on Unity3D, a multiplatform game engine, was tried to be
developed. Unity3D, as an integrated developed tool, provides itself the functions needed for
game development, so in fact all games can be developed, and as required, the functions can
be modified to meet the request of a user through Unity3D. In this study, for efficiency of the
game development process, the multiplatform game engine based smart game was planned so
that the game was developed in the form that the game could be played by using the touch
function of a smart phone according to the voice.
