Grid Builder

BUILD THE GRID. CHASE THE PERFECT SEASON. Grid Builder is a draft-and-spin game for motorsport fans. Spin the reel to pull a team and a season from the modern era of racing (2000-2025), then bank one component into your garage. Five slots. One mission: assemble a team good enough to win every single race on the calendar. Going unbeaten is the dream. Pulling it off is another story. HOW IT WORKS - Spin to draw a constructor and season at random. - Bank one piece from that team-season into an open slot: Driver 1, Driver 2, Team Principal, Chassis, or Power Unit. - Fill all five slots, then run the season simulation. - Watch it play out race by race. Win them all and you go unbeaten. Drop one and the run is over. REAL DATA, REAL RATINGS Every driver, chassis and power unit is rated from actual season results across 2000-2025 - points share, wins, poles, teammate head-to-head and reliability all feed the numbers. That means the legends really do rate like legends, and the midfield grind really is a grind. No hand-waving, no made-up stats. THREE DIFFICULTIES - ROOKIE: more re-spins, friendlier draws, a kinder win bar. - PRO: a balanced test of your team-building instincts. - LEGEND: scarce re-spins, brutal draws, and a win bar that only a truly stacked grid can clear. RE-SPINS Hate the draw? Burn a re-spin to reject it and try again - but you only get so many, and on Legend they are precious. Knowing when to gamble and when to take the pick is the whole game. SHARE YOUR RUN Every result generates a clean, shareable card with your full five-slot grid, your team rating, and your final tally. Post your unbeaten run and dare your friends to beat it. A FEW THINGS YOU'LL LEARN FAST - A superstar driver can't carry a broken car. - Reliability wins championships - a fast DNF is still a DNF. - The right principal and the right era matter more than you'd think. No accounts. No internet required to play - the entire dataset is bundled in the app. Just spin, build, and find out if you can go flawless. Grid Builder is an independent, unofficial game. It is not affiliated with, endorsed by, or sponsored by Formula 1, the FIA, or any team or driver. All names are used descriptively to reference historical motorsport results.
