The black 8 ball during a billiard pool game told the teenage players, "See, being called on last to be on the team is sometimes the best outcome because you win!The black 8 ball during a billiard pool game proudly yelled, as he slid into the pocket that the player correctly called, "I've rolled longer than the stripes and solids to get here."The black 8 ball during a billiard pool game said, "Having a number painted on your belly sure makes people avoid you...that is, until one player finally calls your name!"
All pool games require that certain balls be identified. If you chose to use a custom set of pool balls with only the markings necessary for a particular game, it would not be contrary to the regulations to do so.
The 8 ball.
There is no spot for the black ball on a pool table.
If someone in a game of straight pool hits another person's ball and then hits the eight ball into the pocket, they do not win the game. In order to win in pool, you must be the first to get all of your balls into the pockets, and you must also get the eight ball into a pocket without touching another person's ball.
This is not possible in any common game of pool. Only Straight Pool allows the balls to be placed in nearly any position to accomplish this - no other common pool game allows placing the balls in that order. The middle of the rack is in between the second and third row of balls. It appears what is being asked is what ball will be in the 5th ball position, with one ball to left and one ball to the right if all the balls are arranged lowest to highest. This would be the 5 ball. However, Straight Pool requires that the 1 ball and the 5 ball be placed in the corners. Therefore, no pool game allows the balls to be placed in the way required - so, any ball may be in the "middle" position depending upon the game of pool being played.
This depends upon the game being played. In English Billiards, there is no black ball. In Pocket Billiards, each game is different - In 7 ball, there is no black ball; In 8 Ball, it goes in the center; In 9 Ball, it may be placed anywhere except the apex; In Straight Pool it can go anyplace except the back to corners.
