It is said that the Herdsman and the Weaver can meet only once a year on Star Festival Day, which is on July 7th, over the Milky Way.
This game is to erase two cards from the Milky Way and let them meet.
You can erase the same card that is adjacent to the top, bottom, left, and right.
If you erase all the cards, the two can meet.
Lets get them together quickly.
