What is a practice effect?
Reduced anxiety, remembered item types, faster strategies, and less novelty all help. Gains are often a few points on full-scale scores and can be larger on speeded or memory subtests. It is not proof that g rose by the same amount.
How long should you wait to retest?
Wechsler manuals specify minimum retest intervals for clinical use. Online quizzes have no such control. Repeating our games daily will improve those games; it will not mint a valid second IQ.
Is coaching cheating?
For high-stakes admissions, undisclosed coaching that teaches the exact item pool is unethical. Learning general puzzle habits is ordinary. Stolen commercial items are illegal and we do not use them.
Do practice effects last?
Some of the bump fades; some strategy stays. That is why serial online scores trend up even when nothing “deep” changed.
What should I do instead of grinding IQ clones?
Sleep, exercise, and reading support cognition more honestly than item memorization. Use trail-making-lite or visual-search as timed attention practice, not as a fake retest of WAIS.
Will this site’s games inflate a real IQ test?
A little familiarity with matrices or analogies might shave seconds off similar tasks, but our items are original and short. They are not a WAIS or Raven prep course.

What Is a Good IQ Score?
An IQ of 100 is exactly average; 110-119 is above average, 120 and up puts you in the top 10% (a genuinely 'good' score), and 130+ is considered gifted. IQ is built on a normal distribution with a mean of 100 and a standard deviation of 15, so most people cluster near the middle.

Your IQ percentile tells you the share of people you scored higher than: an IQ of 100 is the 50th percentile, 115 is about the 84th, 120 is roughly the top 10%, and 130 is roughly the top 2%. The table below maps every major IQ band to its classification, percentile, and share of the population.
IQ Percentile Chart: What Percentile Is My IQ? →Are Online IQ Tests Accurate?
A well-designed online IQ test gives a reliable estimate of your reasoning ability, but it is not a clinical diagnosis — only a proctored test like the WAIS or Stanford-Binet provides that. This test is built on Raven's Progressive Matrices and CHC theory, scored on the standard scale (mean 100, SD 15), with an internal reliability (Cronbach's alpha) of about 0.85-0.92.
Are Online IQ Tests Accurate? →Can You Increase Your IQ?
You can meaningfully sharpen reasoning skills, working memory, and test performance through training and education, but raising your underlying general intelligence (g) substantially and permanently is not well supported — core g is largely heritable. The honest answer is that some gains are real and some popular claims are overstated.
Can You Increase Your IQ? →Genius IQ Level: What Number Counts as Genius?
A 'genius' IQ traditionally starts at 140, while 130 and above is labeled 'very superior' on modern tests. Scores that high are extremely rare, and the famous IQ numbers you see for historical figures are almost always estimates, not measured results.
