on 8/8/15Are you using a computer or the app?
With all the memory games to practice why did you get so hung up on that one? Any number of things from the server, type of product or program you are using with the games can cause a problem bu oersonally after playing them all many, many time I think Lumosity does a good job. Mine worked much better on my iPad after I downloaded the app. Might you want to try other games?
