Tic-Tac-Toe Game Server

A simple HTTP-based Tic-Tac-Toe game server implemented in C using the libmicrohttpd library.

Overview

This project implements a web-based Tic-Tac-Toe game where:

• The player plays as 'X'
• The computer plays as 'O'
• The game runs in a web browser
• The game logic is handled by a C-based HTTP server

Features

• Simple, clean web interface
• RESTful API for game interactions
• Computer opponent making random moves
• Full game state tracking
• Win/loss/draw detection

Requirements

• C compiler (gcc or clang)
• libmicrohttpd library
• Standard C libraries (stdio, stdlib, string, time)

Building the Project

[Instructions for building the project would go here.]

Running the Server

This will start the server on port 8888. Open your web browser and navigate to http://localhost:8888 to play the game.

API Endpoints

Endpoint	Method	Description
/	GET	Returns the game interface (HTML)
/move	POST	Makes a player move. Send JSON: {"position": 0-8}
/reset	POST	Resets the game to initial state

Game Board Layout

The game board is represented as a 3x3 grid with positions numbered 0-8:

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

Response Format

Moves return JSON responses in the following format:

{
  "board": [0, 1, 2, 0, 0, 0, 0, 0, 0],
  "message": "Player X's turn",
  "gameOver": false
}

Where:

• board is an array of 9 integers (0=empty, 1=X, 2=O)
• message indicates game status
• gameOver is true when the game has concluded

Architecture

The server uses libmicrohttpd to handle HTTP requests and maintain game state. The application: Initializes the game state

• Processes player moves
• Makes computer moves
• Checks for win/loss/draw conditions
• Returns updated game state to the client
