This App is the mobile version of a card trick (guess a number between 1 & 100).
Please ask someone to memorize a number between 1 and 100. The number should be kept secret. Afterwards you are going to show this person seven different cards with number sequences.
For each card your counterpart needs to check if the memorized number is included on the specific card. The answer can be either "YES" or "NO" and can be provided with the buttons below each card.
After answering the seven questions with "YES" or "NO" an interim page will be displayed, where you can click the magic wand button in order to reveal the result. Before you press the button you might want to use a little magic spell in order to create some tension.
Let's impress your friends with this legerdemain or just enjoy this magic trick yourself.
