About this game

No tedious or complex mathematical calculations are required.

Q.E.D. is a quiz app where you find the answers using only your intuition, logic, and pure "brain power."

Among the top 1% of skilled players, where do you rank?

▪️ No complex calculations! Win solely with pure logic

There are no problems that require a calculator. Anyone can take on the challenge as long as they possess brilliant insight and solid reasoning skills. However, not just anyone can solve them.

▪️ "Descriptive" answers read and graded directly by AI

This is not a simple multiple-choice quiz or short-answer quiz. A smart AI grader reads your submission and determines whether it is correct.

▪️ Select your desired category, such as Math or Creativity

Test the limits of the fields you are confident in! From logic puzzles requiring mathematical intuition to creativity quizzes that break stereotypes, you can choose a category that suits your taste and take on the challenge. ▪️ IQ & Ranking System to Prove Your True Intelligence

Your unique IQ score is calculated based on the highest difficulty problems you have legitimately solved on your own. A fierce top percentage (%) ranking is assigned based on how quickly you solved them.
