Xs&Os / Tic-Tac-Toe / Noughts & Crosses

This is a simulation of the Xs & Os / Tic-Tac-Toe / Noughts & Crosses game with the respective Minimax algorithm implementation, showcased in the Pharo environment using Bloc, Pharo's low-level UI framework. The goal of this work is to representatively show the power of TDD and pure object-oriented programming, with the ability to interact with objects live for an easier debugging experience.

• Note #1: This project was done for a seminar paper. You can download and read the paper over this link (in Serbian). The seminar paper follows the project up until this commit, and from that point onwards documentation found in the codebase supersedes the seminar paper.
• Note #2: Pharo MOOC served as a sort of prerequisite before I started working on the seminar paper. Some info about my progress regarding the MOOC can be found here.
