You need to be familiar with the rules before you can start playing bar-pool. You should know the rules of 8-ball, Rotation and Double tapping as well as Assigning solids and stripes. This will make your game more enjoyable and fun for everyone. Also, make sure you know the proper way to play 8-ball, as it will help you win.
8-ball
Rules for eight ball pool games are different than those used by professional pool players. These rules are not intended for professionals, but the average player. You don't have to read fifteen pages of complex rules in order to play a pool game. Instead, they will help to explain the basics of pool.
No color-based racking is allowed for the eight-ball game. The eight ball must be the most frontmost of the three central balls in this version. Most people put the one infront. You lose a turn if you throw a wrong ball. It is not necessary to call straight-in shots, or touch a rail while taking a shot.

Double tapping
Double tapping, in bar pool rules, refers to the ability to double tap on an item ball by positioning the ball close to it and aiming for it. A cueball is within an inch of an object ball if it is less than 12 inch. It is also called "sharking".
Assigning solids to stripes
A common way to define the style of a game is to assign solids and stripes to bar pool rules. The most popular pool games are those with solids or stripes. These are variations on eight ball. In a game of 8 ball, players use a cue ball to call most aspects of a shot.
Official pool rules forbid hitting your opponent's object balls first. A player who has a striped ball in their pocket ends their turn. The double hit refers to when the cuestick hits the cueball twice within one stroke. This is called a foul.
Etiquette
There are many rules to play pool at a bar. Each bar will have its own rules. Ask before you play. You might also ask about any special rules in effect for the next games. If any rules are in effect, you need to be respectful of them and adhere to them. So everyone can have fun playing the game without causing harm.

It is important that you remember that WPA's "official rules" don't include "dirty swimming pools." Smart pool is a shot that isn't dirty. However, some people consider defensive shots dirty. Intentionally scratched shots are also considered unethical.
