A new interactive game featured on aims to put knowledge in as many hands as possible.
Each video contains an interactive pop quiz that can be taken within the display window on the site.
The company's blog explains further how the game works:
At the end of the video you’ll be asked a question which you should answer using the annotations embedded in the video. This will automatically take you on to the answer, and to the next question. The quiz has five questions in total, each from a different YouTube EDU partner, and then at the end you’ll receive your score.
