If you have downloaded my "test your memory" app and had liked it, here is a new version of it.
The latest version has patterns memory which is supposedly good for spatial memory. A rectangular grid with some cells filled are shown. You have to remember them and tap the filled cells.
Also I have added sound to clicks (or taps) in each game. Good to play with some sound, right? Of course you can disable sound, if you don't like it.
So download the game and enjoy.
