The purpose of this final paper is to create a web application that will enable playing the game of checkers against the application user or against the computer (game agent). The application allows users to wait or search for an opponent. The game against the computer has a level of difficulty to choose, so user can choose between easy, medium or hard level of the checkers game. The application keeps track of the statistics of played checkers games for each user. The field of games is one of the oldest fields of research and application of artificial intelligence. Minimax algorithm with alpha-beta pruning was used for development of the game agent. In order for the algorithm to make decisions as accurate as possible, a heuristic was developed to evaluate the states of the checkers board. ASP.NET Core Framework, programming language C#, Visual Studio development environment, Microsoft SQL Server relational database, Entity Framework Core, SignalR library of ASP.NET, JavaScript, ReactJS, Visual Studio Code development environment, HTML, CSS and Bootstrap were used to develop the application.
