First Nintendo had the DS exercise people’s brains through Brain Age, then it taught users English in English Training DS and the latest training software tests how fast your eyes are. In DS Power of Observation Training players have to follow a box containing a green circle swap places with two other boxes and quickly identify a six digit number when it’s flashed on the screen. Once you’re done with basic training you play mini games set in a sports theme where you have to tap a fast ball as it flies towards the screen. DS Power of Observation Training has an interesting concept that aims to increase reaction time and it’s coming out soon, May 31st soon. I’m on the fence about covering this with a playtest, but if you want to here more about it sound off here.
