The 8 ball
Unless you are supposed to be aiming for the 8 ball, pocketing the 8 ball at any point in the game results in loss.
In 8 Ball this is loss of game under most rules. The 8 ball must be the object ball and struck first under most rules.
Standardized rules, published by the Billiards Congress of America (BCA) dictate that if your opponent scratches and all your object balls are located "in the kitchen", or behind the head string, your object ball which lies closest to the head string, or the 8-ball if all your object balls are off the table, is to be spotted. However, this rule does not apply if you are playing by "ball-in-hand" rules or if "house rules" dictate otherwise. It's always best to ask such questions before the balls are broken.
Depends.... Does the ball "jump" off the table and land on the floor? If so then yes. If it jumps off the table and lands back on with out falling into the pocket then no(like a jump). once the ball (any ball) hits the floor it is a foul. jumps are allowed in billards (except snooker i believe)
If the black 8 ball is the object ball and a foul occurs during the shot, the game is over. This foul is loss of game.
you have to break it and make the 8 ball go in a pocket (at the same time)
Magic 8-ball hears your request. *You shake the magic 8-ball.* The triangle of knowledge says "Please ask again later"
The object ball refers to both the first ball hit by the cue ball and refers to the ball intended to be pocketed, depending upon how the term is used. In most cases, it refers only to the ball that is to be pocketed.
No, when you shake the 8-ball the fluid inside sloshes, causing the object inside to rotate, causing a random answer to appear.
If you're referring to a foul, it's ball in hand for the incoming player, provided it is a cue ball foul (i.e. scratch, ball off table, hitting opponents ball before your own, etc.). I believe some fouls result in loss of turn, but not ball in hand (i.e. - an object ball leaves the table).
As soon as you hit your opponents ball it is a foul. Under most rules, this results in ball in hand. However, under other rules, knocking the 8 ball in when it is not the object ball is loss of game.
