AP Games

The AP Games is the result of the completion of the project Tic-Tac-Toe with AI at JetBrains Academy. This project was developed just for fun and to learn Python and some concepts of a decision-making algorithm.

Tic-Tac-Toe with AI + bonus Reversi game

Tic-tac-toe, is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner.

Reversi

Reversi is a strategy board game for two players who take turns marking the spaces in an 8x8 board.

Each player must place the piece so that an opponent's piece, or a row of opponent's pieces, is flanked by your pieces. All of the opponent's pieces between your pieces are then turned over to become your color. The object of the game is to own more pieces than your opponent when the game is over. See source.

The example below shows the game interface:

	0 - Tic-Tac-Toe;
