Digital Spy writes: "It must have been a tough pitch trying to convince Nintendo bosses that a game based around giving the brain a good workout would be a success; however, fast-forward a couple of years and the Brain Training series has been exactly that. Dr Kawashima's Brain Training is one of the biggest sellers on the DS and is popular among gaming veterans and newcomers of all ages. Aside from units sold, the second biggest clue that a game is doing well is the number of imitations it spawns. A plethora of beat-em-ups arrived after Street Fighter II made a splash, while rhythm action games have popped up everywhere following Guitar Hero's success. The same is also true for Brain Training style puzzle games on the DS."
