Reasoning
challenge
Patterns, numbers and unexpected connections. An IQ-style challenge with explained answers and a clear breakdown of your performance.
This is a reasoning exercise. It does not measure a validated IQ or provide population percentiles.

Number sequences
Find the rule behind the numbers.
Logical deduction
Connect the clues. Find what must follow.
Visual patterns
Spot changes, relationships and combinations.
Spatial reasoning
Imagine rotations, reflections and positions.
Choose your challenge
Choose the length and whether to use a timer. You can skip, revisit and mark questions for review before finishing.
How your score
is calculated
What your score means
You receive one point per correct answer. We show correct answers out of the total, accuracy on answered questions and a breakdown by area. There are no speed bonuses or penalties for changing an answer.
Why we do not give you an IQ number
This original question bank has not been standardised on a representative sample. It cannot establish your IQ, a diagnosis or how you rank against others. Six questions in an area describe this attempt, not a stable personal ability.
Difficulty levels are editorial, not empirically calibrated. Repeat attempts can improve through familiarity. Spanish and English versions are translated exercises, not psychometrically equated tests.
