Results of a study conducted by the Mind Research Network indicates that playing Tetris increases gray matter in the brain, leading to improved brain efficiency and a thicker cortex.

Adolescent girls were chosen for the research, which was conducted over a three-month period. Adolescents were chosen because of the likelihood of researchers to be able to see changes in developing brains, while girls were chosen over boys since the latter group typically has had “considerably more computer game experience and, therefore, may not show detectable brain change after game practice.”

MRI scans were used to assess brain activity and progression.

Co-investigator on the study, Dr. Richard Haier, noted:

Tetris, for the brain, is quite complex. It requires many cognitive processes like attention, hand/eye co-ordination, memory and visual spatial problem solving all working together very quickly. It’s not surprising that we see changes throughout the brain.”
