Estimate how many dots you saw in a brief flash. Ten free Dot Flash rounds add larger quantities, color filtering and memory-only estimation.
Look at the brief dot pattern, then estimate the number with the slider. Once orange distractors appear, only green dots count. Submit to compare your estimate with the actual quantity.
Each three-round stage grows from easy to hard. Color filtering starts in round four. From round seven, the response preview disappears and a delay adds a memory challenge. New mechanics begin with fewer dots; glimpses last 1.2–2.4 seconds.
Estimate a small group and how many groups fit. For dense patterns, compare area and density rather than trying to count every dot.
Ten rounds add up to an Instinct Score of 0–1000. Round limits rise from 40 to 220 points. Instinct’s Core separately measures how accurately you predicted your rank; it waits for at least 30 other comparable attempts. These games are informal benchmarks, not a diagnostic assessment.
