Curiosity grounded in logic
Why IQ Lens is worth trying
Different types of tasks: visual patterns, numbers and spatial reasoning.
A clear process: choose an option, confirm your answer and continue.
Your preliminary result is free, with no registration required.
Sample tasks
Tasks involving patterns, numbers and spatial reasoning.
Sometimes all it takes is looking at something familiar from a different angle.
The test uses different ways of reasoning
- Visual patterns
Compare shapes, positions and numbers of elements, notice changes, and determine which figure should come next.
- Number problems
Look for connections in sequences and relationships between numbers. Sometimes the rule is immediately clear; other times, you need to test several possibilities.
- Logic and comparison
Find the shared principle, identify the odd element out, or choose the option that best fits the conditions of the problem.
Take your time rather than guessing. Examine the details, find the rule, and only then choose your answer.

How long does the test take?
Take your time: there is no countdown or time limit. At the end, you will see how long you took.
What does the result show?
Your result describes how you did on this test's tasks. It does not replace a professional assessment or describe all of a person's abilities.
Do I need to register?
No registration is needed for the basic test.
How much does the test cost?
The current test version and detailed PDF report are available free of charge.
Can I take the test more than once?
Yes. Familiar tasks are easier to solve, though: a repeat result may reflect that you remember the questions and solutions.
What tasks are in the test?
Number sequences, visual patterns, spatial tasks and finding the odd figure out. See the methodology page for details.
Does completion time affect the result?
No. In the current version, time is recorded and shown for context, but it does not affect the preliminary IQ estimate. Breaks may also be included in the total completion time.
Why is the result called preliminary?
IQ Lens currently uses a pilot internal scale. The test has not yet undergone full population norming, so the result should be viewed as an estimate within the current version of the test.
