You must make sure each pool ball is properly stacked in its holder. There should be no space among the balls. The apex ball is the most important in the rack. This serves as the foundation for the rest of the balls. If the apex ball is out of position, the other balls will not fit properly.
Rules to rack pool balls
Rules for pool ball racking are established. These rules are different depending on the type of game and the number played. Some pool rules require that the balls be tapped into place. Others require the use of a rack model. A rack template is commonly found on tournament-level pool table.
Eight-ball pool balls are placed in triangular racks. The first ball is placed in the front, the second one goes at the back of the rack, and the third ball goes in the center. These balls should be placed in the correct order. Although this can seem confusing, once you get the basics, it will become second nature.
Use a racking template
A racking template can be useful when you are trying to rack your pool balls. First, it will prevent your pool balls from sinking into dips by using a template. A template will prevent general feel wear. A template can also prevent clusters from occurring and prevent balls from sliding off the rack.

Third, a racking template will help you maintain the proper balance. When using a racking template, you'll be sure to place the balls in a specific sequence, so that they will always stay in place. For a tight, neat rack you can use alternating colours.
Use a rack with a diamond-shaped design
Place the pool balls in a circle formation when stacking them. You will make sure the balls fit tightly on the rack by doing this. First, place one ball at a point on the diamond. Next, place one ball on each side of the foot. Finally, place nine balls in the center. Next, tighten the rack as tightly as you can without leaving any gaps. Then place the balls in random order.
A diamond-shaped rack is particularly useful for 9 Ball. It has an edge that can prevent the balls from moving, and it's easy to secure the balls with your thumb. Rotating the outer diamond balls can make the rack even closer together. It can be made more secure by inserting your thumb in the bottom of the rear diamond.
A triangular rack is used
Use a triangular rack to store your pool balls. Make sure the balls are tight and securely held in place. If they are not, then they may break or move around, which is not a good result. Rotating the rack is another option that will keep the balls put in place.
A triangular rack will work well for a fifteen-ball game. When you have 14 balls on the table, place the first one on the foot spot and the second on the corner of the back. This allows for you to verify if the final ball is present. If you do not see the last ball, place it on the empty triangle rack. This will ensure the final ball is included with the other 14 balls. You can continue playing once the final ball has been added. To win, you must reach the specified number of points.

Use a regular Triangle
To avoid clustering of balls, use a regular triangle to rack your pool ball. To avoid clustering, the gap between the balls should be as small 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.
You must decide what type of pool balls you want to rack before you can use a triangle to hold them. If you're using a 7-ball rack, you can put any ball at the apex. Many players prefer placing the 1-ball at or near the top of their rack.
