This is a cleanly designed, customizable game of concentration that works well on the iPad's touch screen. There are three challenge levels -- a 4x2 grid with 4 pairs of picture cards; a 6x4 grid with 12 pairs; and an 8x5 grid with 20 pairs.

A correct match displays the name of the animal in one of five user-chosen languages - English, Spanish, French, Russian or Ukrainian - and is also pronounced in that language.

An important feature of this app is the ability to make new cards from pictures in your iPad's photo library. To import a picture, you touch a thumbnail, crop and rotate as needed, type in a name, and record up to 5 seconds of your own narration about the picture. So, for example, it is possible for a teacher to put in items or children from his or her classroom, making this much more than your typical concentration game.
