Psi Number

This App allows you to guess, by telepathy, a number from 1 to 99, selected by any other person.

Works 100% of the times.
Obviously it is a trick and is revealed in full here, so you know what you buy and don't think that is a kind of fraud.
For the person who doesn't know the trick, it's very difficult to know how you can 'guess' always the secret number.


Procedure:
1.- Give the iPhone / iPod touch / iPad to the person you want to read his mind.

2.- This person must select a number from 1 to 99 using the wheel or entering it in the box.

3.- When this person have selected the secret number, must tap 'Select this number' button and must give you the iPhone / iPod touch / iPad.

4.- While you move the blue ball to the upper circle, look the symbols on the right and the left to known the two digits of the secret number.

Move the ball is just a way to take the time you need to interpret the two symbols and to prevent anyone would suggest that you read the mind without looking at the screen.


NOTE: To access to the operation manual of the application, you must enter the number 712 in the box used to enter the secret number.
This isn't mentioned anywhere else, so that in the application itself doesn't appear clues to spoil the fun.
