Jeoparty

Overview

Jeoparty is a real-time, multiplayer Jeopardy-style trivia game built for parties and game nights. One person hosts and judges from their laptop or phone, players buzz in and answer from their own devices, and a shared TV displays the live board, questions, and leaderboard for everyone to follow together.

The idea was born while I was planning my going-away party. As I was brainstorming with friends about what games would be fun to play as a group, we landed on Jeopardy. But the existing options didn't feel very personalized or interactive, so I set out to build my own: a no-setup, no-accounts game you can spin up in seconds and replay with your own questions.

Features

I built Jeoparty end to end as a solo project, using React, TypeScript, and Tailwind CSS, with Supabase (Postgres + Realtime) powering the backend and Vercel for hosting. I built out the following core features:

• Four role-based modes: setup, host, player, and display, each with its own responsive layout tailored to the device it runs on (laptop/phone for the host, phones for players, TV for the shared display)
• Real-time, multiplayer sync: host, player, and display views are synchronized as questions are revealed, answered, and judged, using Supabase Postgres and Realtime to model and broadcast game state
• Live scoring and leaderboard: player scores update in real time, and a final leaderboard is displayed across all modes at the end of each game
• Custom board builder: allows hosts to create their own 5x5 boards with multiple-choice or free-text questions
• Reusable boards: hosts can reload a previous game's board by room code instead of rebuilding it from scratch
• Easy joining: players can hop in with a host-provided link or game code, no accounts or sign-up required

Reflections

Developing Jeoparty was a fun challenge, especially building out multiplayer functionality for the first time. Modeling the game as shared state in Supabase and broadcasting every reveal, answer, and judgment taught me a lot about designing around realtime data and handling the edge cases that come with multiple people performing multiple actions at once. The best part was testing it live with fifteen of my friends at my party and seeing everyone get so competitive :) It's since been deployed and is playable by anyone with a room code. Try it out with your friends or family!
