Memory ace is an app which sharpens your memory while you play. It has four different games - Simon, Patterns, Cards and Faces. Simon game is similar to the Simon says. It has 4 coloured buttons each of which produces a different note. The app glows buttons in some sequences along with their notes. You need to reproduce it. First one button, then two, then three etc. This game attracts kids and adults because of its musical quality. Patterns games shows a pattern in a grid for few seconds. You have to click on this boxes. The size of grid increases as you move to higher leves. Cards is similar to memory game you played with playing cards as a child. To start with 8 cards are shown face down. You tap on a card to open it. If two consecutive cards you open are of same type, you have cleared them. If not, they are again closed. Face activity is a game which shows 2 faces to start with. Then one of the faces is removed. You have to identify if out of the given four options. Number of faces increases as you go to higher levels. All the faces are from Simpsons family. So all in all, you play, have fun and give some exercise to your gray cells.
