This is not a game it is a teaching tool, like Brain age. And at 60 I am too old to tolerate being lectured at and upbraided by an icon. Also I am never going to be remotely as fast as a youngster will be. Another deficit being that on the game where you have to write in the missing letter too often it incorrectly indentified the letter I wrote which was the correct one the first time around. It should be marketed as a teaching tool for school aged kids and those just past school age who need further work on vocabulary and spelling. But it has absolutely nothing to offer any reasonably intelligent person over 35.
