Guessr47.
for Rewkers
A multiplayer location-guessing game for video-game maps. Host uploads map screenshots with answer pins; players join via short code from chat and guess locations on stream. GeoGuessr for video games.
The problem.
Rewkers wanted a stream-side party game that pulled the audience into the broadcast directly — something playable from anywhere with a short join code, not yet-another-overlay watching the host.
What was built.
- Multiplayer real-time game with sync + async modes
- Twitch OAuth player auth (no separate signup)
- Host-side map upload + answer-pin placement
- Live scoreboard + round timer
- Short code join (paste in chat, players load in)
- Convex backend with realtime subscriptions
- Custom design tokens for brand-matched look
The stack.
React / TypeScript / Vite / Convex / Twitch OAuth
