At first I didnt understand how to select the card with the up/down, left/right motion, but as soon as I got it down and memorized the correct patterns and motions, I preformed the trick flawlessly! It only took about 10mins to memorize it too. It was also the beat purchase Ive made and Ive spent about 20$ on apps.
