Minna de Kitaeru Zenno Training is an arcade brain training game released in late 2006 by Bandai Namco, created under the supervision of the smartest disembodied head we know, Dr. Ryuta Kawashima. Much like Brain Age, it uses a touch screen to present simple mathematical and logical tasks. But unlike Brain Age, Zenno Training is on a huge screen in the middle of a game center.
It's quite amazing how popular brain training has become! We wonder if Bandai Namco expects people to go back to the arcade every day for training. That would be so diabolical!
