IQScore Cognitive Assessment
Our full IQ test. Answer 36 reasoning questions across pattern, number, logical and applied reasoning, then get an estimated IQ score, a section breakdown and a review of every question you missed.
Number Memory Test
A number flashes on screen and disappears. Type it back from memory, and every correct answer adds one more digit.
Reaction Time Test
Click the instant the screen turns green. Five rounds give you an average reaction speed in milliseconds.
Visual Memory Test
Memorise a pattern of squares, then tap them from memory. The grid grows as you get better.
Chimp Test
Study the numbered squares, tap 1 and the rest are covered. Can you clear the board from memory?
Stroop Test
Name the ink colour, not the word. Twenty rounds reveal how well you handle distraction and your personal Stroop effect.

What are brain games?
Brain games are short, structured tasks that challenge specific mental skills such as memory, attention and reaction speed. Each IQScore game gives you a measurable result, so you can see where you stand and try to beat your own best.
Do brain games make you smarter?
Practice reliably improves how well you perform on the specific game you play. Research on whether that improvement carries over to general intelligence or everyday life is mixed, so we present our games as a quick and enjoyable way to check in on your skills, not as a guaranteed way to raise your IQ.
How the IQ test and brain games fit together
The cognitive assessment looks at broad reasoning and gives an estimated IQ score. The brain games zoom in on one skill at a time. Together they give you a fuller picture of how you think. You can also read more about how IQScore works.

What is the difference between the IQ test and the brain games?
