Bank Pool: Full Rules, Shot Calling, and How to Play
What Is Bank Pool?
Bank pool is one of the most demanding disciplines in American pool. Every single ball must be pocketed off at least one rail, no direct shots allowed. That constraint sounds simple, but it fundamentally changes how you think about the table. Where regular eight-ball rewards a player who can run balls efficiently in straight lines, bank pool rewards those who can read angles, control speed, and execute under pressure. It’s a game that strips away luck and puts geometry, touch, and nerve front and center.
The game has deep roots in American pool halls and has produced some of the sharpest shooters the sport has ever seen. Players like Efren Reyes and Eddie Taylor built legendary reputations on the bank table. If you want to sharpen your cue ball control and your understanding of angles, there’s no better game to study and play.
Equipment and Setup
Bank pool is played on a standard 9-foot American pool table, though 7-foot and 8-foot tables are used in casual settings. The full-size table is preferred for serious play because the longer distances amplify angle errors and demand more precise speed control. The game uses a standard set of fifteen numbered object balls and a cue ball. If you’re building a dedicated practice setup, it’s worth checking a quality pool table buyer’s guide to understand how table responsiveness and cushion condition affect banking.
Cushion condition matters enormously in bank pool. Dead, flat cushions change your angles unpredictably. Lively cushions return the ball with more energy and at a more consistent angle. Before you start adjusting your aiming system, make sure the cushions on your table are in good shape, a warped or dead cushion will teach you the wrong angles. Similarly, the cloth speed affects how much the ball slows before it reaches the pocket. Faster cloth means the ball carries more of its original angle; slower cloth means more angle loss. Know your table.
A standard rack is used, with all fifteen balls racked in a triangle. There is no specific ball placement requirement in most bank pool formats, balls are racked randomly, though some players and house rules place the one ball on the foot spot. The breaking player must drive at least four balls to the rails on the break, or it is a foul.
Full Rules of Bank Pool
The Object of the Game
The first player to legally pocket eight balls wins the game (in a fifteen-ball set). Some short-rack formats use nine balls and require five to win. In either format, every pocketed ball must contact at least one rail before dropping into the pocket. A ball that goes directly from cue ball contact into a pocket, no matter how clean the shot, does not count and is returned to the table.
Calling Shots
Bank pool is a call-shot game, and the calling rules are stricter than in most pool disciplines. Before each shot, the shooter must nominate both the ball and the pocket. That’s the basic requirement, shared with games like nine-ball and eight-ball. But bank pool goes further: you must also indicate the general nature of the bank, specifically, which rail or rails the ball will contact.
In practice, most players and referees use a “ball and pocket” call in casual play, with the understanding that the ball must bank to get there. In formal or tournament play, if a ball crosses more rails than called, for example, you call a one-rail bank and it rattles around three rails before dropping, whether that counts depends on the specific rules in use. The BCA and many tournament formats rule that the ball must pocket in the called pocket via a bank, and if it pockets via an unintended path, it does not count. Always clarify the calling convention before you play.
Combination banks, where you use the cue ball to drive one ball into a rail, which then drives another ball into a pocket via a bank, are legal but must be called in full. Slop does not count in bank pool. If a ball drops without matching the called shot, it is spotted and your turn ends.
Legal Break
The breaking player must strike the rack from behind the head string. At least four balls must contact a rail or rails on the break, otherwise it is an illegal break and the incoming player can accept the table as is or request a re-rack. If the breaker pockets a ball on the break via a bank, they continue their inning. If a ball is pocketed on the break directly (without contacting a rail), it is spotted, some rule sets also award the incoming player ball-in-hand behind the head string. Confirm the local rule before play.
Fouls and Penalties
Standard pool fouls apply: failure to contact the called ball first, scratching the cue ball, driving no balls to a rail after contact, shooting out of turn. In bank pool, the penalty for most fouls is ball-in-hand for the incoming player, they can place the cue ball anywhere on the table. This is different from some older rule sets where the penalty was simply cue ball in hand behind the head string, so again, clarify before you play.
A scratch (cue ball in pocket) on a bank shot is a foul. The incoming player gets ball-in-hand. There is no special penalty for a scratch beyond ball-in-hand in modern rule sets, though in some money games a scratched ball is spotted and the opponent simply shoots from where the cue ball lies, establish the rules upfront.
If a pocketed ball is not a legal bank (it went directly into the pocket), it is spotted on the foot spot and the shooter’s turn ends. It is not treated as a foul unless the shooter also failed to contact a rail with any ball after the hit. This distinction matters, you can miss the bank and not foul, but you lose your turn and the ball comes back out.
Spotting Balls
Balls that need to be spotted, either because they were pocketed illegally or returned due to a foul, are placed on the foot spot. If the foot spot is occupied, the ball is placed as close to the foot spot as possible toward the foot rail, touching the spotted ball. If multiple balls need spotting, they are lined up toward the foot rail.
Understanding Bank Angles
The Mirror Angle System
The starting point for banking is the mirror angle, also called the equal-angle or diamond system baseline. The idea is simple: the angle of incidence equals the angle of reflection. Draw an imaginary line from the target pocket to the rail, then mirror it back, the ball should arrive at the pocket. This works reasonably well on a perfect table with a new ball at low speed, but real-world conditions mean you need to adjust.
Speed is the biggest variable. A ball hit hard compresses the cushion more and tends to narrow its exit angle, it comes off the rail at a shallower angle than a mirror reflection would predict. This is called a short bank or the ball “shortening.” A ball hit softly bounces more naturally and may even run slightly longer than the mirror angle predicts, especially on lively cushions. Most players learn their home table well enough to compensate instinctively, but on an unfamiliar table, always take a practice read before big shots.
Sidespin (English) applied to the object ball at contact also affects the bank angle. If you hit the cue ball with right English, the cue ball spins right and imparts a small amount of running or checking spin to the object ball depending on the angle of contact. For most bank pool shots, you want to minimize English on the cue ball to keep object ball spin predictable. When you do use English deliberately, to widen or narrow a bank, you’re using what’s called transferred spin, and it requires a lot of practice to control reliably.
The Diamond System
Most serious bank players use some version of the diamond system, which assigns numbers to the diamonds (the inlaid sights) on the rails and uses those numbers to calculate where to aim the cue ball on the rail to send the object ball to the target pocket. The classic three-rail kicking system can be adapted for bank shots. The full diamond system is a topic in its own right, but the core concept is: number the long rail diamonds 0 through 4 (pocket to pocket), number the short rail diamonds 0 through 2, and use subtraction to find your aiming diamond. Different systems use different numbering conventions, so pick one and stick to it, mixing systems creates confusion.
The diamond system is a starting point, not a guarantee. Table conditions, ball wear, and speed all introduce variation. Use the diamonds to get in the ballpark, then let feel and experience refine the shot.
Shot Selection and Strategy
Which Ball to Bank
In bank pool, you’re not just trying to pocket one ball, you’re thinking about where the cue ball ends up after the bank so you have another shot. This is harder than in straight pool because the cue ball often travels a significant distance after the object ball banks, and predicting where it lands requires understanding both the object ball’s path and the cue ball’s residual path.
Prioritize balls that are near a rail and already set up at a natural banking angle. A ball sitting six inches from a long rail with a clear path to a corner pocket is a far better option than a ball in the center of the table that requires a hard cross-corner bank with minimal margin for error. Angle and proximity to the rail are your two primary criteria when selecting which ball to shoot.
Avoid cross-corner banks when a cross-side or short-angle bank is available, cross-corner banks cover more distance and are harder to control for speed. The longer the bank, the more small errors in angle and speed are amplified by the time the ball reaches the pocket.
Cue Ball Control After the Bank
Most intermediate bank pool players focus entirely on getting the object ball to the pocket and forget to think about cue ball position. The cue ball doesn’t just stop after you hit the object ball, it continues, and where it goes determines whether you have a next shot. Use follow (top spin) to send the cue ball forward after contact, draw (back spin) to bring it back, and stun (no spin) to stop it close to where it hit the object ball. On bank shots, stun is often your friend because the object ball is going away from you toward the rail, and a stun shot keeps the cue ball central and roughly where it started.
Learn to control speed with your bridge and stroke rather than with English. For bank pool specifically, keeping your cue ball spin neutral gives you more predictable object ball behavior off the rail. If you want to start using English deliberately for position, read up on your cue selection, a cue with appropriate tip hardness and consistent deflection helps when you’re applying side spin for position play.
Drills to Improve Your Banking
The Straight-Back Bank Drill
Place an object ball on the center of the foot spot. Shoot it straight into the foot rail and try to bank it back up the table into the top corner pocket. This is a straight-back bank with no angle. It isolates speed control and center-ball contact. Hit it softly and count how many out of ten you can drop. Then hit it at medium pace. Then hard. You’ll see immediately how speed changes where the ball returns. Do this on both corner pockets.
Cross-Side Bank Drill
Set the object ball on the second diamond from the corner on the long rail. Shoot it into the short rail and bank it to the opposite side pocket. This is a classic cross-side bank. Set up the shot from different cue ball positions and practice getting the object ball within a diamond of the pocket, then tighten it to getting it in. This shot is one of the most common in bank pool and is worth hundreds of repetitions.
Progressive Rail Drill
Place balls at each of the five diamonds along one long rail, each about six inches from the rail. Work your way down the table banking each ball to a called pocket. Try to maintain cue ball position as you move from ball to ball. This simulates actual game conditions where you must both pocket the ball and think about where you’re going next.
Common Mistakes in Bank Pool
The most common error is hitting bank shots too hard. Players instinctively add pace to make sure the ball reaches the pocket, but extra speed shortens the angle and sends the ball past the pocket. Most missed banks in pool rooms go short and long, short of the pocket because of excessive speed, long of the pocket because of insufficient speed combined with heavy cloth. Practice hitting your banks with less pace than you think you need.
The second common mistake is aiming at the rail rather than visualizing the full path of the ball to the pocket. You should be looking at the end point, the pocket, and working backward to find where the ball needs to contact the rail. Players who stare at the contact point on the rail tend to aim there and lose track of where the ball is actually going.
Finally, many players neglect pre-shot routine consistency. Banking requires a repeatable stroke. If your backswing, address, and delivery vary shot to shot, your banks will scatter. Keep your stroke smooth, your grip relaxed, and your follow-through straight. Bank pool is a discipline that punishes mechanical inconsistency more than almost any other game.
Frequently Asked Questions
Can you use combinations in bank pool?
Yes, combinations are legal in bank pool, but the ball that is ultimately pocketed must still bank off at least one rail before going in the pocket. You must call the shot in full, the ball you’re hitting first, the ball being banked, and the pocket. If you pot the wrong ball or the ball drops without banking, it doesn’t count and the ball is spotted.
What happens if a ball goes in directly without banking in bank pool?
A ball pocketed directly, without contacting a rail, is not counted. It is returned to the table and spotted on the foot spot. Your turn ends, but it is not necessarily a foul unless you also failed to drive a ball to a rail after contact. The distinction matters: a non-bank pocket is a miss and spot, not automatically a foul.
How many balls do you need to win in bank pool?
In the standard fifteen-ball format, the first player to legally bank and pocket eight balls wins. In a short-rack format with nine balls racked, the target is five legally banked balls. The winning number is always just over half the balls in play. Some money game formats use race-to formats across multiple racks rather than a single rack, which you should agree on before play begins.
