According to a University of Edinburgh Study, games like Sudoku can reawaken 'survival genes' in brains
Mastiff announced that according to a recent study conducted at the University of Edinburgh, games such as Sudoku can awaken 'survival genes' that lay dormant in the human brain. These survival genes make the brain cells live longer and resist disease, strokes and the effects of drugs. Mastiff will be releasing Dr. Sudoku for the Game Boy Advance in March 2006. The game features hundreds of puzzle problems, a tutorial mode, help for those moments when you really are stuck, the ability to 'pencil in' possible solutions, and a puzzle problem creation mode.
