IQ Test Challenge

How smart are you – compared to everyone else? IQ Test Challenge is a free IQ test with classic intelligence puzzles. After every test you see where you stand: among all players and among people like you, by country, age group, gender and education.

THE IQ TEST
Ten tasks from six categories, getting harder as you go. No time limit – think as long as you like. At the end you review your answers, submit them and see your score, your IQ estimate with its range and your percentile on the distribution curve of all players. Then go through every task with its solution and explanation.

SIX CATEGORIES OF CLASSIC PUZZLES
- Patterns: Raven-style matrices, figure series, figure analogies, the odd one out
- Numbers: number series, number grids, number pyramids, balances, missing operators, clock angles
- Spatial: cube nets, rotation vs. mirror image, counting cubes, mazes
- Memory: figure grids, n-back, digit span
- Logic: syllogisms, seating plans, knights and knaves, assignment puzzles
- Words: analogies, odd word out, anagrams, proverbs, hidden words

Every puzzle is generated fresh – you will not run out of tasks.

COMPARE YOURSELF
The comparison is the heart of the app. See how many players solve a task, which answer others picked and how your result compares with the whole community. Your data stays anonymous: no account, no sign-up, and your profile details are optional.

MORE WAYS TO PLAY
- Daily challenge: five tasks, the same for everyone in the world, with a daily ranking
- Sudden death: one task after another, one mistake ends the run. With leaderboards worldwide, per country and per week
- Duel: challenge friends with a code – same five tasks, who scores more?
- Training: practise a single category without a score
- XP, levels, 20 badges and your daily streak
- Statistics: your strengths and weaknesses per category, history and IQ estimate over all tests

IN SIX LANGUAGES
English, German, Spanish, Italian, Portuguese and French – the word puzzles are written for each language.

FREE, NO ADS
The IQ test and all game modes are free and without ads: three IQ tests on your first day, then one test and one sudden death run per day. The Club membership (monthly or yearly) unlocks more: explanations for every task, up to five IQ tests a day, unlimited sudden death, your percentile in every comparison group, all details of your past tests and a crown in the rankings – and you support the further development of the app. The subscription renews automatically and can be cancelled at any time in your store account settings.
