Draw a perfect circle, square, triangle and pentagram freehand. Play ten shape drawing rounds and compare your outline with ideal geometry.
Draw the illustrated shape with one continuous stroke per outline, using mouse, touch or pen. The reference stays visible. Release the last required outline to reveal fitted ideal geometry and normalized deviations. Time does not add points.
Circle, square and equilateral triangle; rectangle, right isosceles triangle and semicircle; regular pentagon, hexagon and crossing pentagram; a circle inscribed in a square.
Draw large. Close the outline once. Mouse, touch, pen and compact fields have separate comparisons.
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.
