A bowling spare is a ten-pin bowling scoring result in which the bowler knocks down all ten pins using the two deliveries available in an ordinary frame, but does not knock down all ten with the first delivery. It is represented by a slash on a traditional score sheet and is worth ten pins plus the number of pins knocked down by the bowler's next delivery. The spare therefore differs from a strike primarily in timing.
A strike clears the entire pin deck with one ball, while a spare requires the bowler to use the second ball to remove the remaining pins. The scoring bonus makes the next delivery important because it determines the final value of the spare frame. If the next ball knocks down eight pins, the spare frame ultimately scores eighteen. If the next ball is a strike, the spare frame ultimately scores twenty.
Spare shooting is one of the most important technical skills in ten-pin bowling because even strong bowlers frequently leave pins standing after the first delivery. A player who can consistently convert remaining pins prevents open frames and preserves scoring opportunities. Spare configurations vary enormously. A single remaining pin may require a relatively straightforward straight shot, while widely separated pins can require specialised targeting and ball control.
Bowlers often use a plastic or polyester spare ball with relatively low hook potential to reduce the influence of lane friction and make the trajectory more predictable. Some players use their primary ball for certain spares, particularly when the geometry or distance requires a particular reaction. The objective remains consistent: deliver the ball so that the remaining pin or pins are legally knocked down on the second attempt.
The scoring of a spare differs fundamentally from the scoring of an open frame. An open frame records the total number of pins knocked down over the two deliveries and receives no subsequent bonus. A spare records ten pins immediately but remains incomplete until the next delivery occurs. This deferred scoring means that the ball following a spare is especially valuable.
A strike immediately after a spare causes the spare frame to score twenty, while a delivery knocking down only a few pins produces a lower total. The spare bonus therefore rewards maintaining offensive momentum. In the tenth frame, a spare earns one additional delivery because there is no eleventh frame from which to obtain the bonus. That extra delivery determines the final value of the tenth frame.
Spare formations have specialised names and techniques. A single pin is often described by its numerical position, while combinations of remaining pins can create configurations that are more or less difficult to convert. Corner pins, such as the seven pin and ten pin, can be challenging because they stand near the outer edges of the pin deck and require precise lateral targeting.
Splits are particularly difficult arrangements in which pins remain separated by a gap that prevents a conventional direct path from easily knocking down all of them. Some spare attempts can be made with a straight trajectory, while others require a controlled angle or deliberate deflection off another pin. Spare shooting is consequently a technical discipline in its own right rather than merely a secondary activity after an unsuccessful strike attempt.
The most effective spare strategy depends on the bowler's handedness, release, ball choice, lane condition and remaining pin configuration. Many bowlers develop a spare system based on standing position and target board, allowing them to make predictable adjustments for different pins. A straight spare ball can reduce uncertainty because the ball travels with less lateral movement than a strongly hooking strike ball.
This is particularly useful for distant corner pins, where excessive hook can cause the ball to miss the intended target. Nevertheless, a single universal spare system does not work identically for every player because release mechanics and lane conditions differ. The important principle is repeatability: the bowler needs a reliable method of sending the ball through the appropriate part of the pin deck.
A spare can occur after many different first ball outcomes. A player may leave a single pin, several adjacent pins, a cluster, a corner pin or a split. The first ball therefore determines not only the immediate pinfall but also the difficulty of the second delivery. Bowlers often evaluate the quality of a first ball partly by whether it leaves a manageable spare.
A ball that knocks down nine pins and leaves one easily convertible pin can be strategically more useful than a ball that knocks down eight while leaving a difficult split. This does not mean nine pins are always preferable because scoring depends on the complete sequence, but it demonstrates why bowling performance is not measured solely by raw first ball pinfall.
Spare conversion percentage is an important bowling performance statistic. A player with a high spare conversion rate can turn many non strike first balls into completed ten pin frames, limiting open frames and maintaining a stable scoring average. Missed spares are particularly costly because they remove the bonus opportunity and leave the player with an open frame. Competitive bowlers therefore devote substantial practice time to spare shooting, including corner pins, washouts and split combinations.
Mental routines are also important because the player must reset after a poor first delivery, identify the remaining configuration accurately and execute the second shot without becoming distracted by the previous outcome. Spare shooting demonstrates that bowling success requires both high scoring potential and error management.
The bowling spare is therefore a central scoring and tactical concept rather than simply the act of knocking down the final pins left standing. Its formal definition is all ten pins being cleared with two deliveries in a frame after the first delivery failed to clear them all. Its score is ten plus the next delivery, and its practical importance lies in converting imperfect first balls into completed scoring frames. Spare shooting requires accurate targeting, appropriate equipment, knowledge of pin geometry, lane awareness and repeatable technique. Understanding spares also explains why a bowler can perform well without striking every frame, provided remaining pins are consistently converted and the resulting bonus opportunities are exploited.
