Project Apex: Race Engineer

You are the Chief Engineer. You do not drive the car — you design it. Every day, every engineer in the world gets the same circuit, the same weather, and the same budget. Eight engineering decisions. One submission. No undo. Then the car runs three laps, and the numbers tell you exactly what your choices were worth. THE DAILY ASSIGNMENT A new circuit at midnight UTC, with its own weather and its own credit budget. Most days the stewards outlaw one component, and you have to build around the ban. Choose across eight systems — engine mode, tires, aerodynamics, suspension, gear ratio, cooling, brakes and reliability — then lock it in and live with it. NO LUCK. NONE. The simulation is fixed-point and fully deterministic. The same setup produces the same lap time on any device, forever. There is no dice roll hiding behind a bad result. If you were slow, you were wrong, and the debrief will show you where. THE DEBRIEF Your lap, sector by sector, measured against the fastest legal setup that existed that day — found by solving every one of the thousands of legal combinations. See exactly how much time each sector cost you, what percentage of possible setups you beat, and what your Chief Engineer would change next time. LEARN, THEN PROVE IT Experiment replays today's exact conditions with a different setup as many times as you like, and never touches your official result. Quick Race throws you a surprise circuit. Test Lab lets you pick the circuit, weather and budget yourself. COMPETE A global leaderboard each day. Everyone's setups stay sealed until the day closes, so nobody can copy the leader's answer while the race is still on. Build a streak by submitting on consecutive days. No ads. No in-app purchases. No accounts to create. There is no option without a cost. That is the game.
