Magic Numbers: Mind Reader

Think of a number from 1 to 60. Flip six cards. Name their number. It looks like mind reading, and it works every time. Magic Numbers is the classic card trick, and Hamdouchi Interactive's first app, from 2009. It is rebuilt from scratch and ready to amaze your family, your friends and your class. HOW THE TRICK GOES Ask a friend to pick a secret number from 1 to 60. Show them six cards, one at a time, and ask: "Is your number on this card?" After the last card, you name their number. The app never tells you the answer. You do the quick addition in your head, and that is the magic. THE SECRET Learn how it works, in plain words for kids: - How to do the trick: what to say, the one secret, a worked example and tips for a smooth show. - Why it works: a short lesson from place value to binary, with six switches that show any number from 1 to 63 in decimal and binary. - Practice: the app hides a number, you add up the cards and check your answer. SECRET LOCK Keep the secret safe. Set your own 4-digit code, and The Secret asks for it every time the app opens. If you forget it, your device passcode or Face ID lets you set a new one.
