ぐりぐり都道府県 is an educational game available for iPhone users. Developed by Haruyoshi Arakawa, this free app falls under the category of Education & Reference.

In this game, players can test their knowledge of Japanese prefectures by moving a virtual joystick to find and place the correct prefecture according to the given clue. By answering correctly, players earn in-game coins that can be used to unlock additional features.

As players progress and answer more questions correctly, they will accumulate information about the different prefectures. Collecting festival destinations and food diaries will complete the illustrated guidebook.

The main character, "しろいくま" (White Bear), can be found relaxing in the "しろいくまるーむ" (White Bear Room). As the room becomes more enriched, the bear may undergo changes.

Players can use the coins they earn in the game to purchase items from the Penguin Company and enhance their room with new decorations.

There are two game modes available: answering five random questions or answering all 47 prefectures in random order. The game offers two difficulty levels, starting with "ふつう" (Normal) and progressing to the more challenging "ほんき" (Serious).

Get ready to embark on a fun and educational journey through the prefectures of Japan with ぐりぐり都道府県!
