Challenge
What needed to be solved
Build a simple but technically solid multiplayer game with authentication, persistent player data, room system, realtime updates and a competitive rating flow.
Project Tic Tac Toe
Tic Tac Toe
TicTacToe is a realtime multiplayer online game built as a full-stack project with authentication, player accounts, room-based gameplay, rating logic and persistent match history. New users are redirected to the sign-in page, can register a new account, customize their avatar, review their game history and then either create a room or join an existing one. The lobby page supports realtime updates and infinite scroll for available rooms, while the gameplay itself includes live state synchronization, rating changes and dynamic score updates between players.
