Doodle Champion Island Games, sometimes also referred to as simply Champion Island, is a 2021 role-playing browser game developed by Google in partnership with Studio 4°C. The game acted as an interactive Google Doodle in celebration of the 2020 Summer Olympics and 2020 Summer Paralympics as well as Japanese folklore and culture. The story follows Lucky the Cat as she competes in sport events across Champion Matches to become the champion of the island, whilst completing multiple side quests by helping people who are in need. The Doodle was removed on 6 September 2021 by Google but can still be played in Google Doodle archives.
