One Pocket Rules: How to Play One Pocket

The Chess of Pool

One pocket is the game that separates players who memorize shots from players who actually think. In every other pool game, you have six pockets to work with. In one pocket, you have one, your one, at the foot end of the table, and your opponent has theirs. Every ball you pocket must go into your pocket, or it doesn't count. Every ball you accidentally pocket into their pocket counts for them, not you.

That single rule change transforms pool from a shotmaker's game into a positional chess match. You spend more time playing defense than offense. You trap balls behind your pocket. You kick safeties. You move balls one diamond at a time. A complete one-pocket game can last twenty minutes or more between skilled players, with maybe four or five pocketed balls total. That's the beauty of it, every shot matters.

I didn't get one pocket for years. I thought it was boring. Then I watched Efren Reyes play it live in the Philippines on a trip in 2016 and I understood. The game is about controlling space, not about running balls. Since then it's become one of my favorite formats, especially for longer sessions where I want to think more than stroke.

The Rack and Pocket Selection

One pocket uses a standard 15-ball triangle rack, racked on the foot spot with the apex ball on the spot. The arrangement of the balls within the rack doesn't matter, it's not a rotation game. The cue ball is placed anywhere behind the head string for the break.

The two foot-end pockets (the two corner pockets nearest the rack) are the only scoring pockets. Before the break, players choose which one belongs to each of them. The breaker, by tradition, gets the pocket on the side the opponent chooses not to claim, or the pockets are assigned by mutual agreement. In most serious matches, the opponent of the breaker picks their pocket, and the breaker takes the other.

The side pockets and the head-end corner pockets are neutral. Balls that fall into any of those pockets are spotted back on the foot spot, they don't count for either player and don't end the inning.

Object of the Game

First player to legally pocket eight balls into their designated pocket wins the game. That's it. It doesn't matter which eight, any eight of the fifteen object balls count, as long as they go into your pocket on legal shots.

Because you only need eight, the game ends before the rack is cleared most of the time. But getting those eight is hard. Your opponent is actively trying to keep balls away from your pocket, park the cue ball in positions you can't shoot from, and push balls toward their own pocket. It's a war of position more than a race to pocket.

How to Break

The break in one pocket is unlike any other pool game. Because accidentally pocketing balls on the break can help the opponent, players don't hit the rack hard. Instead, the breaker aims for a soft, controlled break designed to leave balls clustered near their own pocket or trapped where the opponent can't easily reach them.

For the break to be legal, the cue ball must contact the rack, and either a ball must be pocketed (into any pocket, but ideally the breaker's) or the cue ball or an object ball must reach a rail after contact. A common pro tactic is to break soft off the side of the rack, drive a few balls slightly toward the breaker's pocket, and leave the cue ball trapped behind the pack.

If a ball accidentally goes into the opponent's pocket on the break, it counts for them. If a ball goes into the breaker's pocket, it counts for the breaker, and they continue shooting. Balls that scatter into neutral pockets are spotted on the foot spot.

Legal Shots

On any shot, the cue ball must contact an object ball. After contact, either a ball must be pocketed OR the cue ball or any object ball must reach a rail. Unlike rotation games, there's no lowest-ball-first rule, you can hit any ball on the table first. This opens up enormous tactical possibilities, because you can play off any ball to execute a safety or a bank.

Only balls that fall into your designated pocket count for you. Balls that fall into your opponent's pocket count for them, and they don't even have to be shooting. If your shot accidentally drives a ball into their pocket, that's their ball. This is why so much of one pocket is about controlling the roll of every object ball, not just the cue.

Balls pocketed in the side pockets or head-end corner pockets are spotted on the foot spot. If there's no room on the foot spot (a ball is already there), the spotted ball goes directly behind the existing ball, as close as possible, on the long string.

Fouls and Penalties

The penalty for a foul in one pocket is both the loss of one ball (one of your already-pocketed balls is spotted back on the foot spot) and ball-in-hand for the opponent behind the head string. The ball-in-hand restriction is a big deal, you can't shoot at any object ball in front of the head string unless you first drive the cue ball past the head string and return. This gives the fouling opponent a real break.

Common fouls include: failing to contact an object ball, failing to drive a ball or the cue ball to a rail after contact, scratching the cue ball, jumping the cue ball off the table, and double-hitting the cue ball. A player who has not yet pocketed any balls still loses a ball, they go to -1. The minimum ball count is unlimited in the negative direction, so you can go into a huge deficit if you keep fouling.

Three consecutive fouls results in loss of game, same rule as 9-ball and 10-ball. Warnings must be issued after the second foul.

Defensive Strategy

One pocket is 70% defense at the high level. The best shot is often not the one that pockets a ball, it's the one that parks the cue ball frozen to a rail opposite your pocket, leaves nothing near your opponent's pocket, and forces them to play a low-percentage kick or bank. This is why the game is called chess, you're thinking two and three shots ahead, constantly.

Key concepts include: 'banking' balls toward your pocket (hitting them to roll one or two diamonds closer to your side), 'moving' clusters (breaking up clumps of balls so they can be picked off individually), and 'pocket hanging' (leaving a ball hanging on the edge of your pocket as an insurance shot later). Efren Reyes is the all-time master of these concepts, watching his matches is the best free education in positional pool you can get.

Never force a shot in one pocket. If the shot isn't clearly there, play safe. The game rewards patience more than any other pool format.

Winning the Game

First player to legally pocket eight balls into their designated pocket wins. In a race, matches are often played as races-to-3 or races-to-5 because each game takes so long. A race-to-5 can take two to three hours at the pro level.

Money games in one pocket often use a handicap system. The weaker player might need to score only six balls while the stronger player needs nine or ten, or the weaker player might get a 'head start' of one or two balls already on their score. Handicaps in one pocket are delicate and negotiated before every match.
