Surprisingly, arguments in pool are often not about who played better, but about where the final black ball is supposed to go. Some say it must be potted in the opposite pocket, others insist on the same pocket as the last object ball, while some players allow any pocket. However, the official 8-ball rules provide a fairly clear answer.
Under the official WPA rules for 8-ball, the black 8-ball does not have to go into a predetermined pocket or automatically into the pocket opposite the one in which the last object ball was potted. A player may choose any of the six pockets, but must correctly call it for the final shot. If the 8-ball ends up in a different pocket, the player loses.
Official rule: the player chooses the pocket for the black ball
The most widely played competitive game involving the black 8-ball is 8-ball. It is played with 15 numbered object balls and a white cue ball. One player is assigned balls 1 through 7, known as solids, while the other gets balls 9 through 15, known as stripes. Only after clearing all seven balls from their group may a player shoot at the black number 8 ball.
The WPA, or World Pool-Billiards Association, recognizes 8-ball as one of its official disciplines and devotes a separate section of its rules to the game. 8-ball is a call-shot game, which means that on the final shot, it must be clear which pocket the player intends for the 8-ball. However, the rules do not designate any one pocket as mandatory for the black ball.
For example, if the easiest direct shot on the black ball is into the left corner pocket, the player may choose that one. They could just as easily choose the right corner, a side pocket or any other pocket. What matters is that the pocket is called or the intention is completely obvious, and that the shot is played without a foul.
The black ball does not have to go into the pocket opposite the last ball
One of the most common house rules is that the black 8-ball must be played into a pocket on the opposite side of the table from the one where the player potted their last object ball. This rule is indeed used in various bars, pool halls and games among friends, but it is not part of the standard WPA rules for 8-ball.
Nor does the reverse variation apply, under which the black ball must go into exactly the same pocket as the last ball from the player's group. Dr. Dave Pool Info, an expert website that summarizes WPA rules and the differences between various rule sets, even lists “last pocket”—requiring the 8-ball to be played into the same pocket as the last ball potted—as an optional game variation or handicap, not a basic rule of 8-ball.
Therefore, unless two players agree on a different house rule before the game, the claim that “the black has to go into the opposite pocket” has no basis in the official WPA rules.
What exactly does calling a pocket mean?
On a standard called shot, the player does not need to describe the ball's entire path. There is no need to state which cushion it will rebound from, whether it will touch another ball along the way or how it will enter the pocket. What matters is the intended ball and the intended pocket.
In a simple situation, the intended shot may be completely obvious. If there is any possibility of doubt, however, the easiest solution is to identify the pocket clearly before taking the shot. With the black 8-ball, this is also a good way to prevent an argument after the game.
Suppose a player calls the top-left corner, but an unexpected rebound sends the black ball into the top-right corner instead. Even though the ball was potted and the shot may have been technically impressive, it does not win the game. Under WPA rules, potting the 8-ball in an uncalled pocket results in the loss of that game.
When may a player shoot at the black ball?
Normally, only after clearing all seven balls from their group. For example, if a player still has one striped ball on the table, they cannot simply pot the black ball and expect to win.
If a player pots the 8-ball too early, they lose the game. This also applies if they pot their last object ball and the 8-ball on the same shot. At the moment the shot was played, the black ball was not yet their legal object ball.
The WPA rules also cover unusual open-table situations that have been clarified in newer versions of the rules. For an ordinary game, however, the most practical rule to remember is simple: clear your group first, then play the 8-ball.
When does potting the black ball mean a loss?
On the final ball, merely getting the 8-ball into a pocket is not enough. It must be a legal winning shot. A player loses in particular if they pot the 8-ball before clearing all of their own balls, pot it in a pocket other than the one called, commit a foul while potting it or drive the black ball off the table.
There is an important distinction between fouling while attempting the 8-ball and fouling while potting it. If the player does not pot the black ball but commits a foul on the shot, the standard penalty normally follows and the opponent receives cue ball in hand. If the player also pots the 8-ball on that same foul shot, however, they lose the game.
What if the black ball is potted on the break?
Here too, the official rules differ from many house variations. Under WPA rules, potting the 8-ball on a legal break does not automatically mean victory.
If the 8-ball is legally potted on the break, the player may choose to have it respotted and continue from the existing position, or have the balls reracked and break again. Therefore, the rule that “the black ball on the break means an instant win,” which is used in some informal games, is not a standard WPA 8-ball rule.
Do not confuse 8-ball with Blackball
The situation is complicated by the fact that the WPA also recognizes a separate discipline called Blackball. It is often played with two colored groups, typically red and yellow balls, plus one black ball. At first glance, it can therefore resemble traditional 8-ball.
Under WPA Blackball rules, however, shots are not called. A player wins after clearing their group and then legally potting the black ball. So if someone simply says, “We're playing pool with a black ball,” that does not necessarily mean they are using exactly the same rules as American 8-ball.
In Slovakia and most of continental Europe, the WPA is the natural point of reference for competitive pool. The European Pocket Billiard Federation, or EPBF, is a member of the WPA and states in its statutes that WPA rules and regulations are binding on the EPBF and its members.
Why does almost everyone have a different rule for the black ball?
8-ball is very often played informally. As a result, hundreds of local variations have emerged over the decades. In one pub, the black ball may have to go into the opposite corner; elsewhere, it must go into the same pocket as the last ball. Some count an 8-ball potted on the break as an instant win, while others require every rebound off a cushion to be called.
Such rules are not “wrong” if the players agree to them in advance. The problem arises only when a local rule is presented as a universal official rule.
The best solution for a friendly game is therefore simple: agree on the rule set before the break. If you are playing under WPA rules, there is no automatically designated opposite or “last” pocket for the final black 8-ball.
So how should you play the final black ball?
If you are playing standard 8-ball under WPA rules, the procedure is simple. First, the player must have potted all the balls in their group. They then choose the pocket in which they want to pot the black 8-ball and, if the intention is not completely obvious, clearly call the pocket to their opponent or the referee.
The player must then legally pot the 8-ball in that specific pocket. It does not matter where the previous ball was potted, which side of the table the chosen pocket is on, or whether it is a corner or side pocket. What matters is that the shot is legal and the ball goes into the correctly chosen pocket.

Dr. Dave Alciatore also clearly explains the rules of 8-ball, including called shots, fouls and situations involving the 8-ball, in a video based on WPA rules.
Summary
If the question of whether the black ball must go into the “opposite” pocket comes up in your next game, the answer under official WPA rules is no. In standard 8-ball, once a player has cleared their group, they may choose any suitable pocket for the 8-ball.
However, they must play it into the called or clearly intended pocket, and the entire shot must be legal. Rules requiring the opposite pocket, the same pocket as the last object ball or a specific corner are house or local variations, not standard WPA rules.
