The fortune teller in action. Move your fingers together one way and then the next.
To tell someone's fortune:
Get them to pick a colour from the colours written on the fortune teller. If it is blue, spell out B L U E, while moving the fortune teller 4 times (the number of letters in Blue)
Now get the person to choose one of the numbers that are shown in the centre of the fortune teller when you finish spelling out the colour. Let's say it is 3. You would move the fortune teller 3 times.
Then the person should choose a number from the ones showing this time. Whichever number they choose, lift up the flat and that is their fortune.
