About IQ Challenge
IQ Challenge is a quick brain-training quiz that mixes arithmetic, number sequences, logic puzzles and digit memory. A new set of questions is generated every round, so no two games are the same.
It is designed for fun and practice. It is not a clinical or standardized intelligence test, and your score should not be taken as a measure of IQ.
Tips and strategy
- Look at the differences between numbers in a sequence.
- For memory questions, group the digits in pairs.
- Read logic questions twice; the trick is often in the wording.
- A fast correct answer is worth more, but a wrong one scores nothing.
How to play
- Pick a difficulty level.
- Answer ten questions: math, number sequences, logic and memory.
- Each question is timed, and faster correct answers score more.
- See your accuracy by question type at the end.
