Tris has a fascinating history: it was played in ancient Rome under the name "terni lapilli" by Roman soldiers. In 1952, it made computer science history as the first game ever played by a computer, through a program called OXO developed for the EDSAC computer.
The game is particularly interesting from a computer science perspective as it's:
- A perfect information game
- A zero-sum game
- Has a known "perfect strategy" (Nash equilibrium)
- Often used to teach game theory and AI basics
- Multiplayer Mode: Play with friends by sharing a unique match link
- AI Player: Test your skills against our AI
- Easy Sharing: Quick game sharing via WhatsApp
- Modern UI: Clean interface with responsive design
- Cache Resource and Session state for game management
- Dialogs for smooth interactions
- Custom CSS for that extra polish

streamlit run app/main.pyThe game is played on a 3x3 grid. Players take turns marking empty cells with their symbol (traditionally X and O). The winner is the first player to get three of their symbols in a row - horizontally, vertically, or diagonally. If all cells are filled without a winner, the game is a draw (known as "patta" in Italian chess terminology).
