Billiards play is greatly popular as a good billiards game gives fun and joy and could be sort of opportunity for socializing. The billiards has different tools and good to know how to use them in the proper way, e.g. the rack… 
A billiards rack is a frame usually made of plastic or wood that is used to organize billiard balls at the beginning of a game. A triangular shaped billiards rack is used for eight-ball, straight pool, one-pocket, snooker, bank pool and many other games.. Each game has unique conventions for racking.

Near the foul spot of the pool table, place one corner of the billiards rack. This corner is referred to as the apex. The proper position to place the racked balls is marked by the foul mark which is a small marking. While it is arranged the yellow ball 1 will be placed at the apex and the ball 8 will be placed in the middle while all other balls will be placed in random order. Amateur competitions place the balls with solid and striped alternatives at the rack. Make sure to push the billiards rack so that the ball at the apex is on the foul mark and that the side that is opposite the apex is close to the end of the table and parallel to it too. It is important that the balls are packed tightly together or when the break shot is made they will not break properly. So that is why it is a good idea to push the balls forward with your fingers until they are jammed pack.

Various games take up different ordered racking of the balls. Such as for straight pool the 1 ball is placed at the right corner and the 5 ball is placed at the left corner. All other balls stays in order. For a game of bank pool and one ball, the balls may be placed in the billiards rack at random.

Ideally a diamond shaped rack is used for a game of nine-ball billiards but there’s nothing wrong with using a triangular billiard rack as well. The difference with diamond shaped racks are that one of the two corners will be placed as the apex while the other corner will point at the table closest to its end. Remember to place ball 1 at the apex for a game of nine ball billiard because it is expected that the cue ball hits on the lowest numbered ball on the table on each shot. It really doesnt matter how the other balls are placed, though.
