How does Football Bet Builder generate predictions?

We aggregate real-time odds from multiple bookmakers, apply Bayesian probability calibration, and analyse team form, head-to-head records, expected goals (xG) data, and injury reports to generate our predictions.

What is probability calibration in football betting?

Probability calibration adjusts raw bookmaker-implied probabilities using historical accuracy data. Our model learns from verified outcomes to correct systematic biases in different markets like home wins, BTTS, and over/under goals.

How are predictions verified?

Every prediction is automatically checked against official match results from Football-Data.org and ESPN. Verified outcomes are displayed transparently on our Results and Accuracy pages.

What are Smart Acca and Build a Bet?

Smart Acca (auto accumulator) automatically selects the highest-probability picks to build your accumulator. Build a Bet (pick and mix) lets you browse every rated pick across every market, add your favourites to a bet slip, and see combined odds update live.

Honest caveats

No one can guarantee betting profits. Our probabilities are informed estimates, not certainties. Team news and injuries aren't factored in. Always do your own research.

Gamble responsibly. Only bet what you can afford to lose.
