GrandPrixGurus is a free Formula 1 prediction game for individuals and groups of friends. Before each Grand Prix, players predict the top five finishers, the fastest lap, and an odds-based bonus. Sprint predictions are also available when a sprint is scheduled. The game does not involve real money and is not affiliated with the FIA, Formula 1, or the teams mentioned. Players earn three points for each driver placed in the exact position, one point when a predicted driver finishes anywhere in the top five, and an additional bonus for predicting the full top five correctly. Results contribute to season standings, either across all players or within a group of friends. The site also offers head-to-head challenges covering three Grand Prix races, streaks and achievement milestones, and rankings for players, friends, drivers, and teams, updated after each race. A typical session involves submitting predictions before a race, checking the points and standings after the event, and sharing the result through a link or social media story. The service supports French and English, offers phone reminders, and can be installed as an application. It is free to use and does not display advertising.
