BuzzFeed has introduced a multiplayer version of its classic quizzes called Quiz Party, which lets you and up to three friends complete them simultaneously in your browser. The feature gives you a unique URL to share with friends so you can quickly found out, as a group, what geological epoch matches your personality or what Disney princess you are based on your blood type. (Disclaimer: these are not, so far as we know, real BuzzFeed quizzes.)
At the moment the functionality is quite basic. You’re each still essentially completing the quiz on your own, and there’s no chat feature to let you talk to your friends. But it’s a lot more social than simply sharing the results of a quiz on social media, and waiting for friends to complete it in their own time.
