Great idea for kids but to difficult for kids for these reasons:
-Puzzle pieces are to difficult to rotate for children
-Puzzle pieces do not lock in place once they are put in the right location (its to easy to accidently move them out of place)
-Puzzle pieces need to line up almost perfect to fit into place. (need to make it easier for the pieces to fall into place)
-When shaken to mix the puzzle pieces they move to far off to the edge and is difficult to retrieve.
If the programer fixes these problems it will be a great app for kids but until then look somewhere else.
