I'm addicted to NumberWiz. It started well before the app release, when I was playing it in the development environment.
The addiction intensified when I started running it on the device itself. It was so easy to just pick up the sleek iPod touch, fondle its soft steely body, pressing the home button and seeing the raven-black glass screen light up. The enigmatic NumberWiz icon begs to be touched and is seen again at startup. An excellent choice of wallpaper for a lock screen.
As you can see I'm not complaining. As a NumberWiz junkie my mind will only get better, and if I start training, so will my body.
Go out and multiply, NumberWiz gamers!
