WhatsApp and public page
Send a score. Follow your place in the pool.
Fans enter their World Cup predictions through WhatsApp. After each match, the system calculates points, updates the standings, and sends each participant their result. A public leaderboard lets everyone follow the competition while keeping phone numbers private.

A message
The entry is a score sent in a chat. Nothing to install, no account, no app to learn before the first match.
- The thread is the interface
- One prediction per match
The match ends
The collector's event starts the flow. Points for the exact score, winner, or draw never stack: only the best result counts, and each tournament stage applies its own multiplier, up to triple in the final.
- A lock, so a correction never counts twice
- Penalties only score if you called the draw
Back to everyone
Totals are rebuilt from the per-match results, each player receives their finishing position, and the same standings reach the site through a route that strips out phone numbers.
- Standings pushed, not polled
- No nickname means anonymous, never a phone number
