Online Tic-Tac-Toe

Build a browser-based tic-tac-toe. Two players, turn-based, server-validated (no cheating).

What We’re Building

    P1[Player 1<br/>Godot/WebGL] <-->|WSS| Server[EVOID Server<br/>Game Logic]
    P2[Player 2<br/>Godot/WebGL] <-->|WSS| Server

Features:

• Turn-based gameplay
• Server-side validation (impossible to cheat)
• Room system (private games)
• Win/draw detection
• Desktop + WebGL export
• Embeddable in any website (postMessage API)

Why Tic-Tac-Toe?

Simple game, powerful concepts:

• Turn management — who goes when
• Server validation — server decides valid moves
• State sync — both players see the same board
• Win detection — server checks for winners

These patterns scale to chess, checkers, card games, and more.
