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
