Game of TicTacToe with a GUI where the Computer uses the Minimax-Algorithm
To start the Game the core.jar file needs to be added as dependencies, either with a build tool like Gradle or in IntelliJ´s Project Settings.
###IntelliJ
The game always starts with the AI's turn (to make it a bit more challenging ;)).
To make your move just click on a free spot. The AI responds after a few milliseconds. If your first move was not in the center, then the game is already lost.
The AI will test out every possible move before playing, always striving for a win or a draw.
As the AI has the first turn playing and never plays incorrectly, this game is unwinnable.
