It depends which rules you are playing, and there are only two answers. Under the official rules, 8-ball is a call-shot game: you name the ball and the pocket on every shot, and anything that drops elsewhere ends your turn. Under the casual bar rules almost everyone actually learns, only the 8-ball has to be called and everything before it counts however it goes in. The one thing both agree on is that the 8-ball is always nominated.
01
The two rulesets, side by side
The World Pool-Billiard Association and the Billiard Congress of America both publish 8-ball as call-shot. Every shot after the break requires you to indicate a ball and a pocket, and a ball dropped anywhere else does not earn you the next shot. This is what you will play in a tournament, in most organised leagues, and in any room where someone owns a rulebook.
Casual play runs on the opposite default, usually described as “slop counts.” You shoot at your group, whatever falls falls, and you keep shooting as long as one of your own balls went down. The only nominated shot in the rack is the last one.
Official rules: call every shot. Bar rules: call the 8 only. Ask which one you are playing before the break, not after a lucky cross-side drops.
02
What “calling a shot” actually means
A legal call is two pieces of information: which ball, and which pocket. That is the whole requirement. You do not have to describe the route the ball takes, and you are not held to it — the cushions, kisses, caroms, and deflections along the way are irrelevant to whether the shot counts.
This trips up more players than any other part of the rule. If you call the 12-ball in the bottom left corner and it clips the 3-ball on the way, takes a completely different line, and still drops in the bottom left corner, the shot is good. You called the destination, not the journey. Equally, a perfectly struck ball that goes exactly where you planned but into the wrong pocket is not good, however clean it looked.
Extra balls are a bonus rather than a problem: if your called ball drops in its called pocket and others fall on the same stroke, everything stays down and you shoot again.
03
The obvious-ball convention nobody explains
Watch a serious match and you will notice the players barely speak. That is not them ignoring the rule — the published rules say obvious balls and pockets do not have to be indicated out loud. A straight cut into the corner with nothing in the way is obvious.
The safeguard is that your opponent always has the right to ask which ball and which pocket you intend, and you have to answer honestly before you shoot. That single provision is what keeps the convention from becoming a loophole.
The rule of thumb: if a spectator could not name your intended pocket from looking at the table, it is not obvious. Banks, kicks, combinations, and anything travelling more than one rail should be spoken every time.
04
What happens when the ball goes somewhere else
Here is the detail most players get wrong: pocketing a ball in an uncalled pocket is not a foul. Nothing gets spotted, and your opponent does not receive ball in hand. The ball stays down and the turn simply passes.
That changes how bad a wild shot really is. Firing your last stripe up the table and hoping costs you double if it drops in the wrong hole: your opponent inherits the table and you have removed one of the balls obstructing their run. Under call-shot rules the disciplined play is often a safety, not a hopeful pot.
05
The break and the open table
The break is never a called shot. You cannot nominate a pocket, and anything that drops counts. Sinking three balls on a monster break is entirely legal luck under both rulesets.
What surprises people is that a made ball on the break does not choose your group. The table stays open, and the first legally called and pocketed ball after the break is what assigns solids or stripes. Drop two stripes on the break, then call and make a solid, and you are a solids player.
06
The 8-ball is the shot everyone calls
Whatever else is negotiable, the black is not. Every ruleset in ordinary use requires you to nominate a pocket for the 8-ball, and the penalty is the harshest in the game: putting the 8 down in an uncalled pocket is a loss of game, not a foul. There is no version where it is respotted and play continues.
So say the pocket out loud even when the shot is trivially obvious, and point if there is any ambiguity at all. A cross-corner that ends up going cross-side is a loss, and “you knew what I meant” has never once won that argument.
Some house rules add restrictions on top, most commonly banning banks and combinations on the 8-ball. That is a house rule rather than an official one, and it is worth asking about in an unfamiliar room.
07
Playing both versions without arguing
The reason to learn call-shot rules even if you never enter a tournament is that they make you shoot with intent. When every pot has to be declared, hopeful shots stop being free.
A simulator makes the difference easy to feel, because the ruleset is a setting rather than a negotiation. Duel defaults to the casual convention — only the 8-ball needs a nominated pocket — and an optional tournament ruleset extends calling to every shot once the groups are assigned, where a ball dropped in a pocket you did not call stays down but passes the turn. The break is not a called shot in either mode, exactly as the published rules have it.

Common questions
Do you have to call your shots in 8-ball?
Under the official WPA and BCA rules, yes — 8-ball is a call-shot game and you must name both the ball and the pocket on every shot. In casual and bar play the near-universal convention is the opposite: only the 8-ball has to be called, and everything before it counts however it drops. Neither version is wrong, but they produce very different games, so agree on one before the break.
Do you have to call the pocket on the 8-ball?
Yes, in effectively every ruleset in use. The 8-ball is the one shot that casual, league, and tournament rules all agree must be nominated, and dropping it in an uncalled pocket is a loss of game rather than a foul. This is true even when the shot is obvious and even when the 8 was already sitting in the jaws.
What happens if you make a ball in a pocket you did not call?
The ball stays down and your turn ends. Under call-shot rules a ball pocketed in an uncalled pocket is not a foul, so your opponent does not get ball in hand — they simply shoot next with one of your balls already off the table. That is why a wild uncalled shot can help your opponent twice over, by clearing your group and handing them the table.
Do you have to call bank shots and combinations?
You have to call the ball and the pocket, but not the method. Official rules only require naming which ball goes into which pocket — the cushions, kisses, and caroms along the way do not need to be described. In practice banks and combos are never treated as obvious, so say them out loud even in a friendly game.
Do you call your shot on the break?
No. The break is not a called shot in any standard ruleset, and anything that drops counts. The table is still open afterward, so pocketing a stripe on the break does not give you stripes — the first called shot after the break is what assigns the groups.
Is slop allowed in pool?
Slop — a ball that drops somewhere you did not intend — counts in casual and bar rules, which is why those games feel faster and luckier. Under official call-shot rules the slopped ball stays down but the turn passes to your opponent, so luck is neither rewarded nor undone. The 8-ball is never slop in either version: it has to go where you called it.
