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.
- Choose a distinctive branch, corner, or asymmetry on the first object.
- Trace how that feature connects to the rest of the structure.
- 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.
