There are two types of billiards: English and American. They are both rectangular tables. This round billiard table Loop is different from ordinary billiards. The round table has only one hole and four colors. There are four colors of balls: white, yellow, red and black. The hole is not on the edge but on the center line. You only need to use the white ball to hit the yellow, red and black into the hole in sequence. This may sound simple but it is actually better than traditional balls. The table is more difficult to score.
