You must play this Google Doodle puzzle celebrating Ludwig van Beethoven's birthday!Dec 17(AZINS) In its unique way, Google Doodle is celebrating Ludwig van Beethoven's 245th birthday on its home page. The fun part is, you have put together all his sheet music to help him reach the concert hall!

Ludwig van Beethoven is one of the maestros and one of the best composers ever lived. His exact birthday isn't known. Therefore, the time when he was baptised in the year 1770 is celebrated as his birthday.

The Beethoven doodle on Google search page is a puzzle. Your task is to arrange the mixed up sheet music in correct order to complete his work and help him get to the concert hall. The puzzle features his 'Fifth Symphony,' 'Moonlight Sonata,' 'Ode to Joy.' The difficulty in arranging the sheet music increases as you clear the levels.

Google's doodlers were working on the concept for over two years. The biggest challenge they faced was creating something interactive and different than previous Beethoven doodles.

Jordan Thompson, an engineer on the Google Doodle team, said, "We went through a lot of different prototypes for what we wanted a Beethoven doodle to be. But none of them really filled the role of what we wanted, which was to teach people about Beethoven and his music," reports TIME.com

The doodle went live on December 16 and will stay up through December 17.
