About this game

Have fun while making a difference in the fight against littering! A brand-new game experience where taking photos and sorting trash helps develop the world of Yokai. Collect and train Yokai to clean up both the Yokai realm and your real-world streets!

In this game, players gather data on littered trash while having fun. The vast amount of collected data is used to solve social issues, starting with anti-littering measures.


Game Overview & Features

- Snap Litter & Register Info to Get and Train Yokai! Use your smartphone to photograph litter in your city and register details about it to collect and train Yokai!

- Unique Yokai Inspired by Litter In the world of poypoy, Yokai are spirits that manifest through littered trash. Thanks to these charming and unique Yokai, you'll feel a closer connection to the issue of littering!

- Progress Through Photo & Sorting Missions Snap trash anytime using the Camera Button at the bottom of the home screen! When you're at home or on the train, take on "Sorting Missions"—look at photos of trash taken by other players and categorize them. Doing plenty of these two features drives your game progress!

- Get Higher Rewards for Detailed Info After snapping a photo, filling in detailed information about the trash earns you even bigger rewards than just sending a photo alone. Short on time or mobile data? No worries—you can choose "Send Later"!


Community & Competitive Features

- Competitions Host your very own competition! Simply share the ID and password with team representatives to compete in metrics like number of photos taken, completed Sorting Missions, and more!

- Rankings Compete with players worldwide across various leaderboards, including monthly photos taken, completed Sorting Missions, and more!

- Friends Connect with friends to interact in-game! You can even check each other's mission progress.


Other Features

- Field Guide View information on all the Yokai you've collected so far! You can even set your favorite Yokai as your main partner on the home screen.

- Daily Missions Complete daily missions every day to earn extra rewards! Keeping your daily mission streak going might lead to something special...

- Stamp Book As you play the game, earn special stamps in your Stamp Book! Aim to complete your Stamp Book!

- Shop Use "poy," the in-game currency earned from missions, to exchange for various Yokai and items!

- Items (Coming in Future Updates) Utilize items to master the game!

- News & Announcements Check all in-game updates, including admin announcements, item giveaways, and messages from competition organizers. You might even receive special gifts from the admin team...
