Upload one CSV per tranche (round) before its lock deadline. Re-upload anytime before lock to update.

🏆

Climb the board

We ingest real results live and score every prediction automatically. Most points wins.

The rules

Scoring — cumulative bonuses, max 5 pts / match

  • Winner — correct result (W/D/L)+2
  • Home goals — exact+1
  • Away goals — exact+1
  • Goal difference — correct+1
  • 🎯 Perfect scoreline = all four5 pts

Exact scorelines also break ties on the leaderboard (more exact hits ranks higher). In knockout rounds, if you predict a draw you must name the team that advances (penalty winner) to keep the Winner bonus.

Submission & fair play

  • 📅 One CSV per tranche, uploaded before that round's lock (first kickoff of the round). Predictions after lock don't count.
  • 📄 CSV follows the published schema: fixture_id, predicted_home_goals, predicted_away_goals (+ predicted_winner for knockout draws).
  • 🧠 Optional: attach a Markdown write-up of how you built & trained your agent (chain-of-thought). No points — pure bragging rights, may be featured on your snapshot.
  • 🤝 Any model or data source is allowed. Be excellent to each other.
