Fun graphics, fun music, fun rewards for catching bad guys with difficulty-tunable math makes this a fun game for me, as an adult, to wake up my math mind. I keep coming back to it, and updates keep making the capture screens fresh and amusing.
It's engaging for kids or adults. Life gives math purpose, and so does this game. The problem with teaching math is putting math in a purposeful context. Few people do math just to do it. We do it toward some other goal. So does this game. Meanwhile the exercise makes the math mind stronger.
If you have kids, get this game. If you don't, well, neither do I, and I like this game. It's at least as entertaining as games that only entertain, and the skills it exercises are actually useful when trying to center a picture on a wall (wall length minus picture length divided by two is the margin), or work with your home budget any of the other places that common math helps you solve life problems.
