What is the activity of the picture of Fantasy Westward Journey?

Hmm. This is called fireworks. Actually, it's like a lottery ticket.

You can buy it from a wizard next to his surname.

This game is full of F, and the rule is to find a number that is not repeated with others.

The smaller the number that is not repeated on that day, the greater the prize. Down in turn.
