About Find The Odd
Fun brain tests, made with care.
Find The Odd is a collection of quick, playful brain tests — spot-the-odd puzzles, rapid math challenges, and knowledge quizzes. Every test is designed to be played in a few minutes, shared with friends, and — most importantly — fun.
Who's behind this?
Hi, I'm Aren Breur, the creator of Find The Odd. I've spent 30+ years in IT and I love building simple, useful things on the web. Find The Odd started as a personal project to make brain teasers that are actually fun to share — no sign-ups, no tracking walls, just pick a test and play.
How the tests are made
Every test is hand-crafted: questions are written and checked by me, puzzles are generated fresh each round (so no two games are the same), and difficulty is tuned so tests stay fair. If a test feels off, I'd genuinely like to know — that's what the contact page is for.
