Doodle Champion Island Games is an innovative role-playing browser game developed by Google in collaboration with Studio 4°C, launched to celebrate the Tokyo 2020 Olympics. This unique gaming experience combines traditional Japanese folklore with Olympic sports in an engaging pixel-art style adventure.

Released during the Tokyo 2020 Olympics, this interactive Google Doodle quickly became one of Google's most ambitious and well-received game projects, featuring a comprehensive storyline, multiple challenges, and hidden achievements for players to discover.
