It is an incremental game of the Touhou Project where you get the Yin Yang ball that springs up at Hakurei Shrine, level up the facilities of the shrine, turn the gacha to get and level up the character, and develop Hakurei Shrine.

- Facilities and Yin Yang Ball
By raising the facilities of the shrine to level 1 or higher, Yin Yang balls will begin to spring up.
You can get points by touching the Yin Yang ball, and by using the points to level up the facility, the points you can get from the Yin Yang ball will also increase.
There are 6 types of yin and yang balls, blue, green, purple, red, silver, and gold, and the time that springs up differs depending on the color.
Yin Yang balls that spring up early have low points, and Yin Yang balls that take time have high points.
Blue: 3 seconds
Green: 30 seconds
Purple: 5 minutes
Red: 1 hour
Silver: 6 hours
Gold: 12 hours

- Gacha
You can buy a gacha ticket with points and use the ticket to turn the gacha to get a character.
The price of a gacha ticket will increase each time you buy one, but the price will return when the date changes.

- Characters
By leveling up the characters obtained from the gacha, the maximum number of Yin Yang balls will increase, and the time it takes for the Yin Yang balls to jump up will be shortened.

- Affection tap
By tapping the character displayed on the main screen, you can get points according to the character's level, and the character's affection meter will go up.
Depending on the level of the affection meter, the probability of getting double points when tapped will increase.
