Google's Logo Is An Addictive, Multi-Level Video Game To Celebrate The 50th Year Anniversary of Doctor Who

Doctor Who was a science-fiction BBC TV show about a time-traveling humanoid alien.

Today is its 50th year anniversary.

To celebrate that, Google has created an interactive, multi-level game. You choose a character and then try to beat six levels, avoiding aliens, ghosts and more to flip switches, obtain a letter that spells "Google," and get back to a phone booth. Google times you on your mission to grab all the letters.
