To correctly rack pool balls you must ensure that each ball is securely seated in its holder. There should be no space between the balls. The apex is the most important ball in the rack. It serves as the foundation for all the other balls. If the apexball isn't in the correct position, then the other balls won’t fit properly.
Rules to rack pool balls
There are rules to track pool balls in a pool game. These rules can vary depending upon the type of game or number of balls being played. Some pool rules allow you to tap the balls in place while others require you to use a rack template. A rack template is commonly found on tournament-level pool table.
Eight ball pool has the balls placed in a triangular ring. The first ball goes in front. The second ball goes at the back. And the third ball goes in center. It is crucial to arrange the balls correctly. This can be confusing at first, but once it is mastered, it becomes second-nature.
Use a racking template
A template can be used to rack pool balls for many reasons. A template prevents your balls from getting soaked. In addition, using a template will prevent general felt wear. A template will also prevent clusters, and the balls won't slip off the rack.

Third, a rack template will help maintain the balance. A racking template will ensure that the balls are placed in a particular order so they stay in place. For a tight, neat rack you can use alternating colours.
You can use a rack that is diamond-shaped
If you are going to rack pool balls, place them in a set of diamonds. This will ensure the balls have a tight fit on the rack. This is done by placing one ball at the top of the diamond, one on the foot spot and nine in the middle. Then, make sure the rack is as tight as possible, without intentionally leaving gaps. Place the remaining balls in random order.
If you play 9 Ball, a diamond-shaped rack can be very useful. It can keep the balls from rolling and is easy to hold with your thumb. Rotating the outer diamond balls can make the rack even closer together. You can also make it more secure by sliding your thumb into the bottom of the diamond's rear.
Use a triangular rack
To rack your pool ball, use a triangular rack. The balls must be tightly and securely held in their place. If they aren’t tightened, the balls could be loosened or moved, which can lead to them breaking or moving around. You can also try rotating the rack, which will also help keep the balls in place.
Ideal for 15-ball games, a triangular rack works well. If you have 14 balls, place one ball on each foot and another on the corner. This allows you see if there is a last one. If the last ball is missing, place it in an empty triangle rack. This will ensure the final ball is included with the other 14 balls. Once the final ball is included, you can then continue playing. You must score the required number of points to win.

Using a regular triangle
To avoid clustering of balls, use a regular triangle to rack your pool ball. To avoid clusters of balls, the gap between them should be as small and narrow as possible. A gap that is too big can cause the balls to get loose, which could affect your first break. Use a Magic Rack to prevent this. It is affordable and works perfectly.
First, determine what kind of pool balls you want stacked on a regular triangle. If you're using a 7-ball rack, you can put any ball at the apex. Many players prefer to place the 1-ball higher up on the rack.
