A real puzzle from the app. Which number replaces the question mark?
Every answer comes with the "why"
iQz doesn't just mark you right or wrong. It explains the rule behind each puzzle, so next time you spot the pattern faster. That's the difference between guessing and actually training your reasoning.
Five kinds of reasoning
The same puzzle styles you'll find in IQ and aptitude tests.
Abstract
3×3 matrices: find the shape that completes the pattern.
Spatial
Shapes and cube nets you have to picture in your head.
Numerical
Number grids and sequences with hidden rules.
Verbal
Reasoning with words and meanings.
Logical
Deduction puzzles that reward careful thinking.
Hard Only mode
36 hard puzzles free (51 with the extra pack) for when the easy ones get easy.
No ads. No account. No internet needed.
iQz is built to be the opposite of most "brain training" apps. There's nothing to sign up for and nothing interrupting you between puzzles.
The News tab and buying the extra puzzle pack need a connection. Everything else works offline. See our privacy policy.
