Slock, who plays nine more balls, because the game is longer and more difficult, there are fewer people who can play, and girls generally play nine more balls. One hour, the average price is 3-30. In some roadside places, one hour is only from 3 yuan to 6 yuan, so the tablecloth, clubhouse and environment will be worse. Professional billiards venues range from 15 to 30, and student ID cards can be discounted in some places. If the school is under 20, that's enough. I hope I can help you.
