Eight models compute their picks after every draw, benchmarked against 1.9 million simulated tickets and sealed with a fingerprint before the numbers are drawn. Luck is the referee, the scoreboard is public, and the leader's pick is free.
Every model picked each of the last 1,880 draws using only the draws before it. The score is correct numbers; the delta is against pure chance (1,614.6 expected). Inside the band means no signal — which is what the mathematics predicts.
A random line expects the same hits every draw. Over 1,880 draws that expectation is exact, and 1,000 simulated players show how far chance alone wanders. A model only means something outside that band. Ours don't. We publish that.
After each official result the cluster ingests the draw, re-scores all eight models across the whole history, re-runs the luck simulation, writes next-draw picks to an append-only ledger and publishes the hash.
The leader's pick is open. Seven are sealed on the page and open in your inbox — free during launch, sent before every draw.
At launch, all eight picks, the ledger, per-model alerts and the API become a subscription. Founding members keep the launch price. Nothing is charged today.
No. EuroMillions is random; every ball has the same chance every time. Any model — ours included — scores like luck in the long run, and the arena says so. Probabilica is honest computation: models publish, a machine counts, you see exactly how far "AI predictions" get against chance.
Structure and sport: eight published methods, an unedited arena, alerts before each draw, and a ledger you can verify. Nothing here improves your odds, and we will never claim it does.
No. We sell no tickets and take no bets. In the UK, EuroMillions is run by Allwyn under a Gambling Commission licence — play only through the National Lottery. Probabilica is independent.
