QuizQuarters

Overview

A real-time multiplayer quiz app built to explore Socket.IO and event-driven communication.

Problem

Most quiz experiences feel disconnected when players answer from separate devices, with no shared sense of progress or competition.

What I built

• Real-time multiplayer quiz rooms where players can join and compete together.
• Live participant lists and leaderboard updates synchronized through Socket.IO.
• Host-controlled questions with multiple-choice answers and a countdown timer for each question.
• Automatic participant synchronization when players disconnect.

Architecture

React client → Socket.IO event layer → Node.js/Express server → synchronized quiz room state and player updates.

Key technical decisions

• Used event-driven Socket.IO communication to keep question progress, timers, answers, and participant state synchronized across connected clients.

Challenges and how I solved them

• Keeping participant state accurate as players joined, answered, and disconnected in the middle of a live quiz.

Outcome

A working real-time multiplayer quiz experience hosted at quiz-quaters.vercel.app.

What I would improve next

Add persistent quiz history, richer host controls, and more game modes.
