Introducing a new game that teaches players about Yokohama City garbage sorting rules!
Play anytime to learn more about the garbage sorting system.

・About This Game
As garbage and waste items move across the screen, the player touches and drags them to the appropriate wastebaskets.
Putting items in the correct baskets earns the player more points.
Although the items scroll slowly at first, they move faster and faster as time passes.
Try to sort them quickly and accurately!

When a round is over, the player will be awarded a rank based on their score,
and items they placed in the wrongs baskets will be shown along with their correct sorting categories.

Correctly sort as many items as you can and try to achieve the rank of Sorting Master!

Q. What should I do with items when "Waiting for new basket…" is shown?
A. When you fill up one of the wastebaskets with items, Io-kun will come and replace it with a new, empty one.
You can't add new items until Io-kun has brought out the new basket.

Q. Io-kun and Mio-kun sometimes come scrolling across the screen along with the garbage. Should I put them in one of the wastebaskets?
A. Io-kun and Mio-kun are super active, and sometimes they even move across the screen with the other items. It wouldn't be very nice to throw them in a wastebasket, so you can just let them go by.
