Billiard balls are the round spheres used in all the different versions of billiards or pool. It might not seem like there would be much difference in the type of balls used for the game, but there actually is. Each different game for pool and billiards is played with a slightly different size and coating of ball.  Billiard balls are available in a multitude of colors and these colors make them stand out beautifully against the green background of the pool table top. All other games that use a ball to play with, stick to one color. But in billiards you have a myriad of colors that are used. Some games are played with all the balls while others are played with a fixed number and color of balls.

In the USA, pocket billiards is known as pool, so the billiard balls are called pool balls. Pool balls are the most eye catching sports utilities. Most billiard halls believe that the wide range of colors of the billiard balls adds to the enjoyment of the game. You name it and you will probably find a billiard ball in that color from yellow, burgundy, black, orange, purple, blue to red; they have them all. And if all the mono colors were not enough they also have them in double colors. The contrast they create when placed against a green back give the game an aesthetic value of sorts.

To a regular person, the color of the balls is the only difference between them, but a professional pool player will be quick to point out the various differences between different types of pool balls. To a novice player, most of these may not make sense in the beginning but a seasoned player will tell you that the weight of a pool ball is what separates it from the other pool balls. The weight of the pool ball is largely responsible for its performance. As you get better at your game you will realize the difference that the weight of the pool ball makes to your game.

Most pool balls also have a number on them. The balls used for Carom are not numbered but others are. The single colored balls are called solids while the double colored balls are called stripes. For example you may have a yellow ball with the number 1 written on it, the blue and white ball will be ten and a combination of green and white is number fourteen. The normal billiard balls used in most games are smaller than the ones used for Carom. There are also billiard balls available for training. These are marked with target rings that tell the new player exactly where he or she needs to strike.

When not in use, the balls are generally stored in the ball rack. In carom, since the game is played without pockets the balls stay on the table till the end of the game. But in pocket billiards the balls that fall into the pockets, pass through a trough into a collection area where they are held for further use. Today billiard balls are made out of Phenolin resin or polyester and acrylic. These materials make the billiard balls strong enough to sustain shots without chipping or cracking. But before the introduction of synthetic polymers, billiard balls were made out of clay or wood. The rich were known to use ivory balls, but they were a far cry from the durable and colorful billiard balls available today. There are many different billiard balls. Different balls go with different games. Understanding the ones to use for which billiards game is very important.
