Tic-Tac-Toe in Rust

A simple, classic Tic-Tac-Toe game implemented in Rust. This is a command-line interface (CLI) game where a player can compete against a simple, random-moving CPU.

Features

• Command-Line Interface: Play directly from your terminal.
• Player vs. CPU: Challenge a computer opponent.
• Score Tracking: The game keeps a running score of player wins, CPU wins, and ties.
• Simple Game Logic: Uses a straightforward approach to detect wins and ties.

Getting Started

Prerequisites

To run this project, you need to have the Rust programming language and Cargo, its package manager, installed on your system.

You can install Rust by following the instructions on the official Rust website.

Building and Running

1. Clone the repository:

   git clone https://github.com/rogue-87/tic-tac-toe-rs.git  
   cd tic-tac-toe-rs

2. Run the game with Cargo:

   cargo run

How to Play

The game will prompt you to choose a number from 0 to 8 to place your 'X' on the 3x3 grid. The grid layout corresponds to the indices like this:

0 | 1 | 2
--+---+--
3 | 4 | 5
--+---+--
6 | 7 | 8

After each of your turns, the CPU will make its move, and the board will be displayed. The game continues until a player wins or the board is full, resulting in a tie. You can play multiple rounds, and the score will be tracked.

Game Logic

The game logic is implemented within the Game struct in src/main.rs. Key aspects of the implementation include:

• Board Representation: A 9-element array of State enums (X, O, Empty) is used to represent the 3x3 game board.
• CPU AI: The CPU opponent uses a simple random number generator to pick an available spot on the board.
• Win and Tie Detection: The check method systematically scans the board for all possible winning combinations (horizontal, vertical, and diagonal lines). If no winning condition is met and the board is full, a tie is declared.
