Tic-Tac-Toe AI with Aging Mechanics is a modern, strategy-driven reinvention of the classic Tic-Tac-Toe game.

Unlike traditional Tic-Tac-Toe—which is a solved game that almost always ends in a draw with perfect play—this project introduces aging game mechanics, chess-style time control, and AI-powered move analysis to create a constantly evolving and competitive gameplay experience.

Each move has a limited lifespan and expires after a fixed number of turns, forcing players to think beyond static patterns. To prevent infinite gameplay loops caused by expiring pieces, each player is also given a time budget, where the time taken to make a move is deducted—running out of time results in an immediate loss.

The game supports AI opponents, real-time multiplayer, post-game analytics, and strategic insights generated using Google Gemini AI, making it both a fun game and a demonstration of advanced frontend, backend, and AI system design.
