Grid IQ - Measure intelligence

GridIQ is a daily grid puzzle that measures your pattern intelligence on a real Elo-calibrated IQ scale. Solve today's puzzle in under 3 minutes. See your GridIQ — a real number that goes up when you play well and down when you don't. Climb from Beginner to Mastermind through eight intelligence tiers. HOW IT WORKS The grid is divided into rectangles. Each rectangle contains a number — its area. Tap a 1-cell number to place it. Drag across cells for bigger rectangles. Solve faster and more accurately to push your IQ higher. REAL IQ SCORING GridIQ uses Elo math calibrated to the real IQ distribution (mean 100, standard deviation 15). Beating a puzzle harder than your current rating raises your IQ. Underperforming drops it. No participation trophies. DAILY RITUAL One new puzzle every morning, same for everyone in the world. Build a streak by playing each day. Earn streak freezes that save you on missed days. Hit 7, 30, 100, and 365-day milestones. CHALLENGE CAMPAIGN 25 numbered challenges with progressive difficulty.
