Dubbed the Global Candy Cup, the doodle features a competition among four witches “to collect the most candy before the end of Halloween.”
A visitor to Google’s home page can choose to join the teams of the Blue, Red, Yellow, or Green witches.
Google said its art team is behind Team Blue, while engineering is behind Team Green. Production is behind Team Red while External Help is behind Team Yellow.
Google said the teams will “keep playing throughout the day” with members adding to their teams’ scores.
“Only one team will go home with the Cup — will it be yours?” Google said.
