- It covers mental rotation, block design, matrices, and spatial span.
- Vocabulary, analogies, and phonological short-term memory.
- Yes, profiles vary.
- Interests and training matter more than a 12-trial dot cloud.
- No test is fully culture-free.
- Hidden-figures-lite and corsi-blocks for space-ish practice; letter-span-lite and word-recall-lite for verbal-ish practice.
What is the visuospatial side?
It covers mental rotation, block design, matrices, and spatial span. Corsi-style and hidden-figures lite toys echo the family without copying a copyrighted subtest or issuing an IQ.
What is the verbal side?
Vocabulary, analogies, and phonological short-term memory. Letter-span-lite is a forward letter string, not a Wechsler Verbal Comprehension index.
Can one side be high and the other low?
Yes, profiles vary. A gap on a web pair of games is still two noisy toys, not a learning-disability evaluation.
Does a spatial strength mean an engineering career?
Interests and training matter more than a 12-trial dot cloud. Do not hire yourself — or anyone — from a browser score.
Are nonverbal tests “culture-free”?
No test is fully culture-free. Matrices reduce some language load but still reflect schooling and familiarity with diagrams.
What can I try here?
Hidden-figures-lite and corsi-blocks for space-ish practice; letter-span-lite and word-recall-lite for verbal-ish practice. None of them is a clinical IQ.

What Is Attention Control?
Attention control is the skill of holding a current goal and filtering noise — a side conversation, a flashing tab, or a flanking arrow on a screen. It overlaps working memory and inhibition, yet it is not a synonym for IQ, and a browser hit count is not a diagnosis. Labs time tightly controlled trials; this site offers lite practice only, with no clinical battery behind the score.
What Is Attention Control? →IQ and Income
Surveys often find a positive correlation between cognitive-test scores and later earnings, but the path is noisy: education, health, networks, discrimination, and luck all sit in between. A correlation is not a paycheck forecast, and a higher score on a web game here is not a raise, a credential, or a clinical IQ. Group charts never tell you one person’s worth or hiring outcome.
IQ and Income →What Is Cognitive Flexibility?
Cognitive flexibility is the ability to update a rule when the world changes — switching from color to shape, or from one task set to another, without staying stuck. It is one executive-function toy, not a full intelligence profile. Task-switch lite on this site is original practice with no age norms, no standard error, and no clinical IQ attached to the hit count.
What Is Cognitive Flexibility? →Test Norming Basics
Norming is how a published test turns a raw hit count into a number you can compare with a reference group of the same age. Without a documented sample, a standard deviation, and a date, a web score is just a count. This site’s games are not normed batteries and must not be read as a clinical IQ, a school placement, or a medical finding.
Test Norming Basics →What Is a Z-Score?
A z-score says how many standard deviations a result sits from a group mean: (score − mean) / SD. IQ deviation scores are a dressed-up z on a 100/15 scale — but only when the test was actually normed. Typing a web-game total into that formula does not manufacture a clinical IQ, because you still lack the real mean, SD, and sample that the formula assumes.
