Tell your Facebook friends about the DK Quiz
There are two ways to challenge your friends:
1. Click on the 'Challenges' tab at the top of the quiz page and then click on the 'New Challenge' button. Then all you need to do is select a quiz (out of the ones you've completed), select a friend from your list and if you like, attach a message to your challenge.
2. You can choose to challenge your friends to a quiz that you have just played by clicking on the 'Challenge your friends' tab at the end of the quiz. You can then choose the friend that you want to challenge and send them a message. You will only be able to challenge friends who have not already played the quiz. If you want to see how you've done against your friends that have already played the quiz then you can go into your 'Profile' and then into 'My Friends' and click on the 'View Head to Head' button.
