My daughter loves memory, and I like it well enough, too. This version has some nice twists in the two special cards, one of which turns over every card in the game suddenly, the other of which turns over every card that has been previously exposed during the game. You can disable those if you like, as, with all Alligator Apps, everything in the game is fully customizable. I havent played around much at all with customizing it but the options are extensive, including adding your own pictures. I recall that there is even a rather intriguing option to use audio and video together or even turn off the pictures so that you have to remember which word was spoken when each card was turned over. Ive downloaded other Memory apps since and deleted them quite quickly because this one makes them all quite blah in comparison.
