One adaptive test for each trivia category. Every question has already run on a Mind Loft daily gauntlet, and its difficulty comes from how real players did on it, so the test can say where you stand rather than just how many you got. 25 to 30 questions, about eight minutes, harder when you are right and easier when you are not.
The daily gauntlets (Streak, Deep, Atlas, Sport and Biz) are one life and asked in a fixed order, so a day’s results show exactly who reached each question and who got past it. From that, every one of the 5,510 questions here carries a measured difficulty, last calibrated on September 29, 2026. Questions from days that have not run yet are never used, so a test can never spoil a daily.
Your score is IQ shaped but player normed: 100 is the typical Mind Loft player and 15 points is one standard deviation of that field, with a plus or minus that shrinks as you answer. It measures what you know about a subject against the people who play here. Nothing is posted to any leaderboard; your results stay on this device.
