In this tutorial we will be making a Tic-Tac-Toe game (also known as Noughts and Crosses) using nothing more than the built in Unity UI and two basic scripts. The approach to creating the game in this lesson should show two important things. The first is the versatility of the Unity UI toolset. In addition to this, we want to walk through a project by breaking it down into manageable pieces; approaching and solving one problem at a time. We will be following the steps of designing and prototyping that one could take during any game project.
