## What it is

A quiniela is the classic office/family prediction pool. This one needs no accounts — pick a nickname and a PIN — and keeps everyone’s picks in sync in real time.

## What I built

-   Real-time sync with Firebase Firestore.
-   Live scores from a football data API, with standings calculated automatically.
-   Group consensus odds built from everyone’s picks.
-   No build step: plain HTML, CSS and JavaScript. It started inside this website and was later extracted into its own repo.
