How to take the test
Read each row from left to right. Compare the complete tiles and identify which feature changes consistently: the main shape, its color or fill, its direction, or its position inside the scene. Then choose the fourth tile that continues that exact rule. You can click an option or press the number keys 1–4. After 12 items you get accuracy and a full explanation of every answer.
If you do not answer before the time limit, the item counts as an omission but the run continues. Results stay on this device.
Scoring method
The main score is your overall accuracy and the median time on correct items, measured withperformance.now(). Human Arena also reports performance at each difficulty level and the highest difficulty reached. Higher accuracy is better; lower time is better.
Why results vary
Attention, fatigue, screen size, and whether the tab was backgrounded can all shift a result. Treat the number as an entertainment and general-information measurement, not a medical, diagnostic, neurological, or IQ assessment.
What this game challenges
Pattern Reasoning Test measures inductive reasoning: finding the rule that links a series of figures. It is a specific reasoning skill, not a measure of intelligence or overall ability.
Original rule families
Items are generated from original families — rotation, shape, fill, position, alternation, combination, and symmetry — so the content is transparent and not copied from proprietary assessments. None of the items are clinical or diagnostic.
What this result does not mean
This is a game result, not an IQ score or diagnosis. Read the scoring methods and measurement limits.
