GIGABRAIN FIELD MANUAL

Mental Rotation Test

Mental Rotation compares two three-dimensional voxel structures. Decide whether they are the same object viewed from another angle or a mirrored impostor that rotation cannot reproduce.

How to play

Objective: Classify true rotations and mirrored structures with high accuracy.

  1. Choose a distinctive branch, corner, or asymmetry on the first object.
  2. Trace how that feature connects to the rest of the structure.
  3. Decide same when a rotation can align every feature, otherwise choose mirrored.

How scoring works

Accuracy drives the GigaScore with a steep curve, and every correct answer counts. A 50/50 guessing run stays low while consistent spatial reasoning rises quickly.

GIGABRAIN is an entertainment game and personal arcade benchmark, not an IQ, medical, or diagnostic test.

Tips for a cleaner run

  • Compare connectivity before comparing the overall silhouette.
  • Track one unusual corner through the imagined rotation.
  • If a local feature has reversed handedness, the structure is mirrored.

Mental Rotation Test questions

Can a mirror image match after enough rotation?

No. Rotation changes viewpoint but does not reverse the handedness of the structure.

Does answering faster increase the score?

Response time is shown as a useful result stat, but the current benchmark score prioritizes correctness to prevent rapid guessing.
