Using the site
The games here are free to play for personal enjoyment. You do not need an account. Please do not attempt to disrupt the site for other people, scrape it at a volume that degrades it for others, or automate the AI report feature to consume its capacity.
It is a simulation, provided as-is
Everything here is a model of Formula 1, not a record of it. Ratings are our own estimates, race results are generated by simulation, and the site is provided without warranty of any kind. We do not guarantee the site will be available, accurate, or free of errors, and we are not liable for any loss arising from using it.
No betting
The race predictor outputs probabilities from a simulation. It is not a tip, a forecast or betting advice, and it has no knowledge of real-world form, upgrades, penalties or news. Do not use this site as a basis for gambling.
