Band: Explorer Challenger Mastermind Grandmaster Gauntlet

Now sitting Explorer (Grades 3-5). IQ is age-relative by definition, so each band draws its puzzles from its own difficulty range - a younger child is never measured on whether they have met the content yet.

16 puzzles. 12 minutes. Mostly FIGURES - rotations, mirrors, and matrix patterns in the format culture-fair tests use - plus a few number and letter series, getting trickier as you go. Skipping is allowed; wrong answers cost nothing extra, so guess when you are stuck.

⚠️ This is a puzzle game, not a clinical IQ test - real IQ testing is done by professionals with validated instruments. Your score here measures one thing: how you did on these 16 puzzles today.
