By using this simple trick you can win free drinks from your friend! Simply ask your friend to open their calculator and times 3 x 5 x any single numbers until they reach a 9 digits number.
Ask them to tell you 8 of the digits in any order but keep 1 a secret, if you guess this number they will buy you that number of drinks (they can not choose 0).
As they tell you each number use the slider in the app to enter each number.
The app will reveal their secret number...... sounds impossible, try it, it really works.
This app supports the message 'Don't Drink and Drive', we hope that people using this in bars and pubs will be reminded not to drink and drive.
