How a match works
Pick Ranked or Casual, select a game type. We find you an opponent at your ELO.
Both players see the same brief at the same moment. Timer starts. Build.
Build on your own machine, deploy wherever you want — Vercel, Netlify, Railway.
Paste your live URL before the clock hits zero. Late submissions forfeit.
Lighthouse runs against both URLs. Performance, Accessibility, SEO, and speed bonus.
Results screen shows scores side-by-side. ELO shifts. Streak tracked. Rematch?
