Core Brain’s page describes an IQ score of 194 as exceptionally rare, but it does not establish a reliable population frequency for that result. On the customary IQ scale, 194 is about 6.27 standard deviations above the mean; that calculation describes a position on a statistical model, not a verified count of people who score that high on Core Brain’s test.
What Core Brain says about an IQ of 194
Core Brain’s page for a score of 194 labels it “Profoundly Gifted,” displays a percentile of 100.0th, and gives two different rarity descriptions: “in roughly 1 in millions of people” and “Roughly 1 in Infinity people score this high or higher.” Those statements do not provide a consistent, usable estimate of how many people would receive the score. Core Brain’s IQ 194 page
The page also promotes a 20-minute test and says it assesses six areas: pattern, numeric, verbal, spatial, logic, and matrix. These are Core Brain’s descriptions of its own test and score; the page does not independently demonstrate that the test can measure IQ accurately at this extreme.
What 194 means on the customary IQ scale
Deviation IQ scores are commonly centered on a mean of 100, with a standard deviation usually set at 15 points. The American Psychological Association describes these conventions in its definition of intelligence quotient; OpenStax also describes a modern IQ scale with a mean of 100 and standard deviation of 15 in its psychology textbook.

Using those parameters, the calculation is (194 − 100) ÷ 15 = about 6.27. In other words, 194 sits roughly 6.27 standard deviations above the mean on that conventional scale. This is a mathematical comparison, not an observed prevalence figure for Core Brain users or the general population.
Why the displayed percentile does not settle rarity
A displayed percentile of 100.0th is rounded. At the far upper end, that rounded value cannot distinguish among extremely high scores or tell a reader how many people actually score at or above 194. Turning a model-based position into a real-world frequency requires evidence that the particular test measures reliably in that range and an appropriate norm sample. The available information on Core Brain’s page does not establish either.

So the most accurate answer is that 194 is extraordinarily far above the mean under the conventional IQ model, but the exact rarity of a Core Brain score of 194 is unknown. The page’s “1 in millions” and “1 in Infinity” language should be treated as claims made by Core Brain, not as validated statistics.
Quick Recap
Best Value
- SLIDE, DON'T LIFT — IQ Flow is the freshest twist yet on the compact brain teaser: you fill the grid by sliding pieces in from the edges, with no lifting allowed. That single rule turns a familiar packing puzzle into a real test of planning and foresight, because every slide affects the ones that follow. It works your concentration, planning, logic, spatial insight and problem solving — and it's every bit as absorbing for a grown-up as for a child.
- 120 CHALLENGES, EASY TO EXPERT — FOR AGES 7 TO ADULT — With 120 challenges of steadily rising difficulty, IQ Flow is a genuine all-ages brain teaser with a clever wrinkle: challenges show you the goal, not the starting position, so you always begin from an empty board. Early challenges ease you in; the Master level reveals only the wave pattern on top of each piece, demanding a whole new way of thinking. A 7-year-old and a puzzle-loving adult can each find their level. One solution per challenge.
- SLIDE THE PIECES IN AND GO WITH THE FLOW — Choose a challenge, then fill the central grid by sliding the pieces inwards from the open sides of the board — you can't drop them in from above, and some edges are blocked. Sometimes you'll need to move pieces already on the board, sliding them out and back in, to make room for the rest. Plan your route, because one early slide can ripple across the whole board. One solution each time — can you go with the flow?
- COMPACT, PORTABLE & MADE FOR EVERY GENERATION — The whole game packs into a compact case with a secure travel lid, so there are no loose pieces to lose on a plane, in the car or at a restaurant.
