Stimulate your gray matter and lower your “Brain Age” by playing the piano, calculating change, unscrambling words, drawing free-form connect-the-dot figures and more. The sequel to a generally well-received “Brain Age” doesn’t leave much room for disappointment. While the touch screen’s recognition of numbers and letters can get pretty frustrating when you’re trying to reach the optimal “Brain Age,” the positives of this title far outweigh the marginal negative.

Fun mini-games aside, “Brain Age 2” tracks and graphically displays your scores for each exercise over the course of two months, using the first attempt from each day. Add in Dr. Kawashima’s fun brain stimulation techniques and 100 sudoku puzzles, and you’ve got a combination of education and entertainment that’s fun for everyone. Grade: A
