To rack pool balls for 8-ball, set all fifteen in the triangle with the front ball on the foot spot, the 8-ball in the middle of the third row, and one solid and one stripe in the two back corners. Everything else can go anywhere. Then press the pack tight so every ball touches its neighbours and lift the triangle away cleanly. That is the whole rule; the rest of this page is how to do it well.
01
Where the rack sits on the table
The triangle goes at the foot end of the table, the end opposite where the breaker stands. Five rows fill it: one ball at the front, then two, three, four, and five. The front ball is called the apex ball, and it sits directly on the foot spot.
If your table has no dot marking the spot, find it with the diamonds. Count two diamonds up each long rail from the foot end and picture a line joining them across the table. The foot spot is the middle of that line. Most cloths show a worn patch there anyway.
The back row of five must run parallel to the foot rail. A rack that is twisted even slightly sends the break off to one side and makes the spread uneven, so sight along the back edge of the triangle against the rail before you let go.
02
The only three placement rules
Under the standard world rules for 8-ball, exactly three positions in the rack are fixed.
The apex ball is on the foot spot. Any ball may be the apex ball. What matters is where it sits.
The 8-ball is in the middle of the third row. That is the dead centre of the triangle, with a ball on each side of it. It is the most protected position in the pack, which is the point: the game-deciding ball should be the one least likely to fly into a pocket on the opening shot.
The back corners are one solid and one stripe. Which goes left and which goes right does not matter. Corner balls are the ones most likely to travel toward a pocket on the break, so splitting the groups there stops the rack from favouring one of them.
The other twelve balls are placed at random. You do not need to sort them, and you are not supposed to arrange them to help yourself.
Before lifting the triangle, look at three things: black ball in the centre, two different groups in the back corners, front ball on the spot. If those are right, the rack is legal.
03
Three things people think are rules
Solids and stripes must alternate. They do not. An alternating pattern is tidy and harmless, and it happens to satisfy the corner rule automatically, which is probably why it spread. But two solids sitting side by side is not a fault.
The 1-ball must be at the front. Not in standard 8-ball. Some leagues and many bar tables do it by custom, and it is fine to follow the house, but the rulebook does not ask for it. The confusion comes from 9-ball and 10-ball, where the 1-ball really is required at the apex.
The balls go in number order. No pool game played with a triangle requires numerical order through the rack. If you have been lining up 1 through 15, you have been doing extra work.
04
How to make the rack tight
Placement makes a rack legal. Tightness makes it break properly. When the cue ball hits the apex, energy passes through the pack ball to ball. Every gap is a place where that energy is lost, and a rack with gaps near the front can absorb a hard break and barely move.
The method that works on almost any table takes four moves. Load the balls with the triangle sitting a little behind the spot. Slide the whole thing forward until the apex ball arrives on the foot spot. Put your fingers behind the back row, inside the triangle, and press the pack forward so all fifteen are squeezed toward the apex. Then take your fingers out and lift the triangle straight up, front edge last, without touching a ball.
Now look at it from the side before anyone shoots. The three front balls matter most. If you can see cloth between the apex ball and either ball behind it, rack again.
When one ball keeps drifting away from its neighbours, the cause is almost always the table rather than you. Years of racks wear small craters into the cloth around the spot, and balls settle into them. Swap the wandering ball for another, rotate the pack, or move the whole rack forward or back by a hair. On a very worn table a perfect rack may not exist; aim for a frozen front three and accept the rest.
Tapping a ball down with another ball to seat it works, but it dents the cloth and makes the next rack worse. Most rooms would rather you did not. Pressing forward with your fingers gets the same result and leaves the table alone.
05
Who racks, and what the breaker can ask for
The traditional arrangement is that the player who is not breaking racks for the one who is. Many leagues and tournaments have moved to rack your own, where the breaker sets the balls and the opponent is free to look them over. Agree which you are using before the first game.
Whoever racks, the breaker is entitled to a tight one. Asking for a re-rack because the front balls are gapped is normal and not rude. What is rude is the reverse: racking loosely on purpose to spoil someone’s break. It is against the spirit of every ruleset and explicitly penalised in most of them.
The triangle itself is only a tool. Thin template racks that stay under the balls during the break are common in tournaments because they produce a frozen pack every time. On a phone there is nothing to do at all; a game such as Duel sets the balls for you, so every break starts from the same tight pack.
06
Racking 9-ball, briefly
Since the two games get mixed up, here is the difference. 9-ball uses only balls 1 through 9, set in a diamond: rows of one, two, three, two, and one. The 1-ball goes at the apex on the foot spot, the 9-ball goes in the centre, and the other seven are random. You can form the diamond inside a standard triangle by pushing the balls to the front, or use a diamond-shaped rack made for it.
Everything about tightness applies equally. With fewer balls in the pack, a single gap matters even more.

Common questions
How do you rack pool balls for 8-ball?
Put all fifteen object balls in the triangle with the apex ball on the foot spot and the back row parallel to the foot rail. The 8-ball goes in the middle of the third row, and the two back corners hold one solid and one stripe. Every other ball can go anywhere, and all fifteen should be pressed together so each ball touches its neighbours.
Where does the 8-ball go in the rack?
The 8-ball goes in the middle of the third row, which is the centre of the triangle. Counting from the apex, the rows hold one, two, three, four, and five balls, so the 8 sits with two balls ahead of it on each side and a full row behind it. That central position makes it the ball least likely to drop on the break.
Does the 1-ball have to go at the front of an 8-ball rack?
Not under the standard world rules, which let any ball sit at the apex. Some leagues and plenty of bar tables do put the 1-ball in front by custom, so ask before the first game if it matters to the people you are playing. In 9-ball and 10-ball it is different: the 1-ball must be at the apex.
Do solids and stripes have to alternate in the rack?
No. The only requirement about groups is that the two back corner balls are one solid and one stripe. Alternating the rest is a common habit and does no harm, but the rules treat the remaining balls as random, and a rack is not illegal because two solids or two stripes sit side by side.
How do you get a tight rack?
Slide the loaded triangle forward until the apex ball is on the foot spot, then press the balls forward from the back row with your fingers so the whole pack is squeezed toward the apex. Check that the front three balls are touching, because a gap there costs the most, and lift the triangle straight up without brushing a ball. If one ball keeps rolling away, swap it with another or shift the rack a hair, since the cloth is usually worn at that spot.
Who racks the balls in pool?
In most casual games and under the standard rules, the player who is not breaking racks for the breaker. Many leagues and tournaments now use rack your own instead, where the breaker racks and the opponent may inspect it. Either way, the breaker is entitled to a tight rack and can ask for it to be redone before shooting.
