You get a link to a quiz created by your friend, who selected all the items from the given list that can be found in his/her room. Click on the link and take the quiz! You'll see the same list. Guess what he/she had chosen. All that you know is the number of the selected things. This is also the number of tries that you can have. When you finish your friend can see the results.
You can see your friends' results by clicking on your quiz link. Those who managed to get all the answers right, score the number of points equal to the number of the things selected by you. It means that if you marked 5 things that can be found in your room - the maximum number of points to score in your quiz is 5.
