Rotate block solids in your mind. Find the same object among reflected and altered shapes in ten free mental rotation rounds.
Study the block solid. One option is the same object after a rotation. Choose among rotations, reflected shapes and altered connections. Use 1–4 or arrow keys. Lock your choice. Time is reported separately and does not add task points.
Turn the object in your mind; count arms and follow their bends. A rotation preserves the connections between blocks. A mirror image reverses the handedness of a bend. Compare the longest arm first, then follow its smaller branches.
Turn the object in your mind; count arms and follow their bends.
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.
