Doodle Champion Island Games is a sports-adventure game released by Google as a "Google Doodle" to celebrate the Tokyo 2020 Olympic Games. The game transports you to an island inspired by Japanese culture. Playing as Lucky, a white ninja cat, you will explore various areas of the island and defeat champions to become a legend of Champion Island. The game features seven minigames based on Olympic sports, including table tennis, skateboarding, archery, rugby, artistic swimming, sport climbing, and the marathon.
Players control Lucky the cat as they explore an island divided into seven zones, each modeled after a different Japanese location. In each zone, you will encounter a champion of a specific sport. Defeating a champion earns you a "Sacred Scroll." Once you have defeated all seven champions, you are honored as the "Island Champion." Players can also join one of four teams, each represented by a specific color and a creature from Japanese mythology. The team with the highest score is declared the winner at the end of the games.
Additionally, each zone offers a variety of quests for players to complete. These tasks typically involve assisting the island's inhabitants by locating items or carrying out sequences of trades. Some side quests allow players to unlock more challenging versions of the original minigames.
