T-9 Ultimate Tic-Tac-Toe

Ultimate Tic-Tac-Toe takes the classic game to the next level with a 3x3 grid of traditional tic-tac-toe boards. The twist? Your opponent's move determines which board you must play on next, creating layers of strategy that transform simple gameplay into complex tactical decision-making.

Built with Go and SvelteKit, T-9 delivers real-time multiplayer gameplay through WebSocket connections, ensuring instant move synchronization and smooth game state management. The system handles complex game logic including board transitions, win conditions across multiple levels, and player matchmaking.
