Multiplayer Quiz Game — TCP/UDP Hybrid

A multiplayer quiz game built with raw Python sockets using a hybrid TCP/UDP architecture. Built as part of the ENCS3320 Computer Networks course at Birzeit University.

Architecture

• TCP → player registration, question broadcast, final results
• UDP → real-time answer submission and feedback

How it Works

1. Players connect via TCP and register with unique usernames
2. Server waits for minimum 2 players then starts the game
3. Server sends questions to all players via TCP
4. Players submit answers via UDP (10 seconds per question)
5. Server sends instant feedback via UDP (Correct / Wrong)
6. After 5 rounds, server announces final scores and winner via TCP

How to Run

Start the server

python server.py

Start each client (in separate terminals)

python client.py
