The Overview

Speed quizzing web application for real-time multiplayer gameplay. Host and contestant roles with live scoring, device-based answer input, and real-time state management over WebSocket.

The Challenge

Speed quizzing requires sub-second state synchronisation across multiple devices. Every millisecond matters in competitive quizzing — no polling, no lag.

The Build

TypeScript/Next.js with WebSocket-based real-time state management. Host and contestant interfaces are separate views of the same state machine. Answer timestamps to sub-second precision for speed-based scoring.

The Result

Genuine real-time multiplayer quiz platform. Zero polling, zero lag, instant feedback — the way competitive quizzing should work.
