The Google Doodle changes for various holidays or events. Today’s is in honor of Jules Verne’s birthday: a 20000 Leagues Under the Seatheme. It’s interactive, but not to the level that the Pacman Google doodle was.
Back in May 2010, the Pacman Google doodle celebrated the 30th anniversary of the Pacman game. You could actually open it in a new browser and play the game: 255 levels of Pacman!
Did you miss that google doodle and still want to play? You can!
