Chapter I General rules of the game

Rule 1. Game - Definition
A ten-pin bowling game consists of ten frames. A player throws two balls in each of the first nine frames, unless a strike occurs on the first message. In the tenth frame, the player throws three balls if a strike or spa is counted. Each frame must end with a player in the usual way.

NOTE: during the Becker (Bakker) team competition, each player in a team performs all consecutive ball throws in one game until all ten frames have been completed.

The correct sending of the ball is considered to be a throw, in which the ball leaves the place where the player is located and crosses the foul line on the game track. Points are counted at each throw, unless an “erroneous ball sending” is declared. Ball throwing must be done manually. You can not use any devices attached or attached to the ball, which can perform auxiliary function when throwing or are a moving part when throwing.

Rule 2. Game - Scoring
Except for the cases when a strike occurred at the first throw, the number of pins hit by a player on the first throw is marked in a small box in the upper left corner of the corresponding frame on the monitor, and the number of pins brought down by a player at the second throw of the ball is marked in a box in the upper right corner of the frame. If none of the pins standing in the frame is knocked down during the second throw of the ball, a dash (-) is placed in the scoring field. The total score for two attempts is calculated and displayed on the monitor immediately.

Rule 3. "Strike"
If at the first throw of the ball in the frame the whole set of pins is knocked down, then the strike is counted. Strike is marked with a sign (X) in a small square in the upper left corner of the corresponding frame. One strike is estimated at 10 points plus the number of pins shot by the player for the next two throws of the ball.

Rule 4. "Double"
Two consecutive strikes are called a double. In this case, the first strike is awarded 20 points plus the number of pins shot down by the player on the first throw of the ball immediately after the second strike.

Rule 5. "Triple"
Three consecutive strikes are called triple. In this case, 30 points are awarded for the first strike. In order to get the maximum number of points equal to 300, the player needs to knock out 12 strikes in succession.

Rule 6. "SPEA"
A spade is counted if the pins remaining to stand after the first throw of the ball get stuck at the second throw of the ball in this frame. Spares are indicated by the sign (/) in the upper right corner of the corresponding frame. In this case, 10 points are added to the spa, plus the number of pins shot by the player during the next throw of the ball.

Rule 7. Open Frame
If a player fails to knock down all 10 pins for two ball throws in one frame, this is called an open frame, if only the pins that continue to stand after the first ball throw do not form a “split”.

Rule 8. "Split"
Split is the position of the few pins remaining to stand after the first throw of the ball, in which the first (head) pin fell and:

At least one pin fell between two or more standing pins, for example, between the 7th and 9th or 3rd and 10th.

At least one pin fell immediately in front of two or more standing pins, for example, 5-6.

NOTE: split is usually indicated on the monitor as (O).

Rule 9. Style of play
The game is carried out on two tracks (one pair), adjacent to each other. Members of competing teams, triples, pairs, or independent players must compete one after the other in the same frame on one track, and go to another track for the next frame until five frames are played on each of the two tracks.

NOTE: in team games in the Bakker system, members of the competing teams, trios and couples, play bowling in a consistent and consistent manner and successive frames in the same game. Teams must change tracks within a pair after ten frames.

Rule 10. Proper knocking down of pins
Throwing the ball is considered perfect when the player sent the ball and the ball crossed the foul line. Every throw of the ball is counted, unless the ball is declared erroneous. Throw the ball should be made only by hand. It is prohibited to use any devices in the composition of the ball itself or attached to it, which are detached after the throw, or which move during the throw.

NOTE: A player can use special equipment to assist in capturing and throwing the ball if it replaces the amputated or crippled hand completely or its main part.

A player is considered to have shot the pins correctly if the following conditions are met:
The pins fell or flew off the ground under the action of a ball or any pins.
The pins fell or flew off the pitch under the action of the pins, rebounded from the side partition or rear side.
The pins fell or flew off the pitch under the action of pins, which rebounded from the cleaning board when it was on the pitch before cleaning the knocked pins.
The pins that leaned and leaned on the wall of the bump or side partition.

All such pins are considered shot down and must be removed from the court before the next throw of the ball.

Rule 11. Incorrect (unauthorized) knocking down of pins
If one of the events listed below occurs, the throw of the ball is counted, and the subsequent knockdown of the pins is not:
The ball goes beyond the track to the pins.
The ball bounces off the tailgate.
The skittle bounces off contact with the body, hands, or feet of the person responsible for setting the skittles.
The pins come in contact with the mechanical installation of the pins.
Any pin drops when removing the knocked down pins.
Any pin falls in contact with the employee responsible for setting the pin.
The player breaks the rules.

The ball is thrown when the knocked pins have not yet been removed from the track or from the gutter and the ball touches these knocked pins before leaving the track surface.

If an improper knocking down of the pins occurs and the player is entitled to additional throws of the ball in this frame, the incorrectly knocked pins or pins should be installed on the place where they initially stood.

Rule 12. Skittles - Wrong Installation
If at the first or second ball throw immediately after the throw it is found that one or several pins are set incorrectly, but all the necessary pins are available, this ball throw and the corresponding result are counted. The responsibility for determining the correct installation of the pins lies with the player. Before making a throw, a player who has noticed an incorrect installation of the pins must insist on their proper installation, otherwise the initial installation of the pins will be considered correct.

It is forbidden to change the position of any pins remaining to stand after throwing the ball. This means that if the pins are moved by the mechanical installation of the pins, they should remain in their new place and their manual rearrangement is prohibited.

Rule 13. Skittles - Rebound
If the pins rebounded and they were left standing on the track, then these pins are considered not knocked down.

Rule 14. Skittles - which ones are considered knocked down.
Only those pins can be considered knocked down, which were actually knocked down or completely removed from the playing surface of the track as a result of the correct throw of the ball.

Rule 15. Skittles - Replacement
In case of breakage or other damage to the pins during the game, this pitch must be replaced with another one, the state and weight of which corresponds as closely as possible to other pins used in the kit. The need to replace the pins is determined by the officials of this tournament.

Rule 16. Wrong ball
The ball is declared erroneous in any of the following cases:
Immediately after throwing the ball (and before the next ball throw on the same track), it turns out that one or several pins from the kit are missing.
The staff member responsible for setting the pins applies to any standing pins before the ball reaches the pins.
The employee in charge of installing the pins removes or touches any fallen pins before it stops.
The player throws the ball is not on its path or not in turn. Or one player from each team on a pair of tracks makes the ball be sent not on its own track.
The presence of physical interference from another player, the spectator or a moving object or employee responsible for setting the pins during the throwing of the ball and before it is completed. In this case, the injured player can either agree with the result of the throw or declare that the ball is wrong.
Any pin shifts or falls when the ball is sent, but before the ball reaches the pins.
The sent ball collides with a foreign object.

When the ball is declared erroneous, the parcel does not count. All the pins that stood when the ball was declared erroneous should be rearranged, and the player gets the opportunity to throw the ball again.

Rule 17. Throw the ball on the wrong track (for official competitions)
NOTE: in accordance with the rules of ETBF and FSBR, all official competitions are held in sport mode (the league system), two, three or four participants compete on one pair of tracks (the number of participants participating on one pair of tracks cannot change during one competition) ;

Each game is conducted by participants on a pair of tracks.

After one, two games (no more), all participants on the team of judges go to other pairs of tracks.

When a ball is declared an erroneous player or players must throw on the correct track in the following cases:

One player throws the ball on the wrong track.

One player from each team on a pair of tracks throws the ball along the wrong track. If several players from the same team take turns throwing the ball along the wrong track, then this frame will be played unchanged. All subsequent frames must start on the right track.

Rule 18. Determination of foul (violation)
A foul (violation) is fixed if a player passes over any part of his body or steps beyond the foul line, and touches any part of the track, equipment or structure (structure) during or after the throw of the ball.

The ball is considered to be in the game until the same or another player takes the place for the next ball throw.

Rule 19. Intentional violation (foul)
If a player in his own interests violates the rules intentionally, the result of this ball throw by this player is annulled, and further throws in this frame are not allowed for this player.

Rule 20. Miscalculation of throwing rules
When fixing the violation (foul), the throw of the ball is counted, but the pins knocked down at this throw are not taken into account. If the player who committed the foul has the right to additional throws of the ball in this frame, then the pins knocked down by the ball during the registration of the foul must be re-installed.

Rule 21. Obvious foul
A foul is recorded, even if it is not detected by an automatic foul recording device or a judge, but the commission of this foul is obvious for the following persons:

For both captains (representatives) or one or more players from competing teams.

For officials following the game and score.

For the official responsible for the tournament.

Rule 22. Foul - Protest
After the announcement of a foul protests are not accepted except for the following cases:

It has been proven that there are failures in the operation of the automatic device for registering a foul.

There is strong evidence that the player did not commit a foul.

NOTE: film and video can be used as evidence, but only if a protest is announced to the main referee of the competition before the player’s next shot in the game is played and an immediate viewing of the controversial episode is possible.

Cinema and video materials submitted after the end of the games are not accepted for consideration and cannot serve as grounds for filing a protest and / or appeal. In the above situation, a protest must be immediately announced to the chief referee of the competition, protests are accepted only from players and / or their official representatives.

Rule 23. Conditional ball
In the case of a protest, the subject of which is a foul, the correct drop of a kegel or an erroneous ball, and which cannot be immediately resolved by the officials responsible for holding the tournament, the player must throw a conditional ball or replay the frame.

In the event of a dispute at the first throw of a player in any frame, or at the second throw of a player in the tenth frame after the strike at the first throw in the tenth frame:

If the controversial situation is resolved, regardless of whether the player has committed a foul or not, the player must complete the frame, and then throw a conditional ball in such an arrangement of pins that would stand if the controversial pins did not fall.

If the subject of the dispute is the doubtful wrong falling of the pins, the player must complete the frame, and then throw the conditional ball into such an arrangement of pins that would stand if the controversial pins did not fall.

If the controversial situation is resolved, regardless of whether the ball should have been declared or not, the player must complete the frame and then play the controversial frame completely.

If a dispute arises in an additional attempt or in the third roll of the tenth frame, then the controversial ball is not appointed, unless the disputed situation is resolved, regardless of whether the ball was mistakenly declared or not. In this case, the conventional ball should be thrown into the same arrangement of pins, which stood when throwing the ball that became the subject of dispute.

Rule 24. Ball - surface change
Changing the surface of the ball during official competitions is prohibited.

NOTE: if it turns out that the player knew in advance that his actions would violate this rule, the result of the game, during which this rule was violated, is subject to cancellation. In addition, the player is suspended from further participation in these competitions. Competition is the rest of the current game and all subsequent games of the tournament.

Rule 25. Foreign objects in the approach zone
The application of any foreign matter to any part of the playing area that adversely affects the normal playing conditions of other players is prohibited. This rule applies, but is not limited to, substances such as talc, pumice and resin on shoes, soft soles or heels that leave marks in the approach zone. It is prohibited to carry talc powder into the playing area.

NOTE: the area for players (playing area) must be determined by the organizers of the competition and approved by the chief judge using identification methods that are understandable to the audience. Access to the zone for finding players (in the immediate vicinity of each pair of tracks on which their players compete) is allowed only for one person (accredited coach or team leader), unless specifically defined.

Rule 26. Errors in account management
Errors in the account management or calculation of the result must be corrected by the responsible person of the tournament immediately after the discovery of the fact of such an error. Disputes should be resolved by a specially authorized person.

Protests against mistakes in account management must be filed no later than one hour after the end of the game or block of games of each day of the tournament, but before awarding prizes or the start of the next round (when playing with knockout), depending on which event occurs earlier.

Each case of filing a protest under this rule is specific, therefore, when considering each specific protest, one should not be guided by the experience of considering similar disputable situations.

NOTES: after registering an account, it cannot be changed unless an obvious error was made in maintaining the account and scoring. Obvious errors should be corrected by the tournament official immediately after their discovery. Decisions on controversial situations are made by the leadership of the tournament. In accordance with the rules of the tournament management can set a specific period for correcting errors. Гейм или фрейм (фреймы) в рамках игры, безвозвратно потерянный в ходе подсчета очков, может быть переигран с одобрения руководства турнира, если только такая процедура не запрещена правилами проведения турнира.

Правило 27. Прерванный фрейм, игра
Если вследствие неисправности оборудования дорожек, на которых идет игра, нормальный ход серии может затянуться, руководство турнира может перенести окончание гейма или серии на другую пару дорожек.

Правило 28. Затяжка игры
1. Игроки, готовящиеся выйти на исходную позицию и выполнить бросок шара, должны иметь следующие права и обязанности:

Они могут потребовать освободить ближайшую левую дорожку при выходе на исходную позицию или подготовке к броску шара.

Эти же правила относятся к игроку, готовящемуся выйти на исходную позицию и выполнить бросок шара по ближайшей правой дорожке.

Игроки должны быть готовы к игре, когда подходит их очередь. Они должны выходить на исходную позицию и выполнять бросок без задержки, при условии, что ближайшие к ним дорожки справа и слева свободны.

2. Если игрок не соблюдает правил, оговоренных в параграфе 1, это может быть расценено как затяжка игры. Игрок, не соблюдающий данных правил, должен быть предупрежден уполномоченным официальным лицом турнира следующим образом:

Устное предупреждение за первое нарушение (без штрафа)

За второе и каждое последующее нарушение в любой игре данного блока игр участнику объявляется предупреждение и на него налагается штраф. Штрафом является аннулирование количества сбитых кеглей в данном (на момент вынесения предупреждения) фрейме.

В целях интерпретации применения данного правила, Судья должен специально контролировать любого игрока или команду (в соревнованиях по Беккеру), которые отстают на более чем 4 фрейма от следующих игроков в соревнованиях в индивидуальном разряде или парах; или более чем на 2 фрейма в соревнованиях троек или команд.

При появлении каких-либо вопросов, касающихся применения данного правила, или их отсутствия, в официальных соревнованиях окончательное решение принимает главный судья.

1.12 Pin installation devices (pinsetters)
Bowling centers that use automatic devices to install pins should ensure their annual verification, which consists in determining the correctness of the installation of pins. In case of detection of deviations in the operation of devices for the installation of pins, approval of such devices will be made only after the elimination of all deficiencies.

1.13 bump stops
The bump or side wall can be completely made of hardwood or from proven and approved synthetic materials. They must be installed parallel to the track.

The bump should start from a point opposite to or no more than 15 inches (381 mm) in front of the position for pins # 1 and pass to the wall of the rear shock absorber.

Specifications of the mine zone for equipment for automatic installation of pins are developed specifically for a specific device for installation of pins at the same time as issuing approval for its use.

1.15 Rear shock absorber
The rear shock absorber should always be covered with black material. At the same time, the design of the rear shock absorber must be such as to prevent the pins from rebounding onto the track.

1.16 Markup or pointers
Markings or pointers applied to paths and sections of the approach must meet the following requirements:

a) At each of the following points of the approach area (the distance is measured to the spade line), up to 7 guidelines can be inserted or applied: 2-6 inches (51-152 mm), 9-10 feet (2743-3048 mm), 11— 12 feet (3353–3658 mm), 14–15 feet (4267–4572 mm). Each series of guide pins should be parallel to the line of interruption (foul), and each guide should be uniform, in the form of a circle, the diameter of which should not exceed? in. (19 mm).

b) At a point at a distance of 6–8 feet (1828–2438 mm) after the spade line and parallel to it, up to 10 guides can be inserted or marked on the track. Each guideline should be uniform, in the form of a circle, the diameter of which should not exceed? in. (19 mm).

c) At a point at a distance of 12–16 feet (3658–4877 mm) after the spade line, up to 7 targets can be inserted or applied. Each goal must be uniform, and may consist of one or more arrows, diamonds, triangular or rectangular pointers. The dimensions of the surface covered by each target should not exceed 1? inches (31.8 mm) wide and 6 inches (152.4 mm) long. Each goal must be located at equal distance from another, and together they must form a single pattern.

d) Inserted markings or indexes should be made of wood or plastic. They should be inserted flush with the surface of the approach plots. When applying the markings, this should be done on unfinished wood, after which the markings should be varnished or similar, transparent material that is commonly used for surface finishing. All such elements, made in any bowling center, should be uniform, both in terms of design and size. Such uniformity should be ensured, at least on a natural pair of tracks.

2. Requirements for processing tracks
For all official competitions held or sanctioned by the FBI, the following requirements should be applied to track processing.

After each application of the conditioner on the lubricated part of the track (including any part of the track processed by the buffer of the machine for applying the conditioner) there must be at least 5 units of the conditioner. Over the entire surface of the lubricated part of the tracks, you must use an air conditioner of the same type and manufacturer. For competitions, the same conditioner and the same treatment methods should be used to lubricate the tracks.

The minimum and maximum processing distance, including the portion of the track processed by the buffer, must be at least 28 feet (8535 mm) and no more than 45 feet (13715 mm). This rule does not mean that the recommended minimum treatment distance is 28 feet. For processing tracks, you can take any value from the range from 28 to 45 feet.

3. Specification of bowling pins
Currently, when checking pins, techniques approved by the ABC / WIBC Technical Specifications Department are used, therefore all pins approved by ABC / WIBC will be approved by the WTBA.

The use of mobile devices in a bowling ball is prohibited, except that it is allowed to insert any device to change the distance between fingers or the size of the holes for the thumb and other fingers, provided that this design of this device ensures its rigid fixation during the throw, and it cannot be removed from the ball without damage. . Over the entire surface of the lubricated part of the tracks, it is necessary to use a lubricant of the same type and manufacturer. During competitions, the same lubricant and the same processing methods should be used to lubricate the tracks.)

It is prohibited to introduce into the ball metal or any other substance other than the original material of the ball used in its manufacture. In addition, any change to the ball resulting in its weight parameters or balancing outside the range specified in the specifications is not allowed, and the use of such balls in competitions held under the auspices of the WTBA is strictly prohibited.

Special plugs can be inserted to re-drill the holes in the ball. A variety of pointers, markings are allowed to be inserted into the ball, provided that they are made flush with the outer surface of the ball. In all cases, they must be made of a material similar (although not necessarily the same) to the original material of the ball. There should not be any foreign material on the outer surface.

These restrictions also apply to both the manufacture and / or any modification of the ball, provided that this does not apply to a conscious overstating of the weight in the process of making the ball, installing inserts or qualified repair.

The circumference of the ball and its weight should not exceed 27 inches (686 mm) and 16 pounds (7.25 kg), respectively. The diameter of any ball must be constant.

There should be no grooves or grooves on the surface of the ball, with the exception of holes or grooves for its grip, identification signs and numbers, random chips or wear stains.

4.3 Parameters to be measured at the venue of the tournament:


a) Gross weight. Must be no more than 16 pounds (7.25 kg).

b) Holes or recesses to grip. Their number should not exceed 5 (five).

c) One hole for balancing is allowed. Its diameter should not exceed 1 1/4 inch (31.8 mm).

d) Vents for fingers and / or thumb holes are allowed. Their diameter should not exceed 1/4 inch (6.4 mm).

4.6 Hardness
The surface hardness of a bowling ball used in any competition under the auspices of FIQ, WTBA must be at least 72 units when measured with a hardness tester “D” at room temperature.

NOTE: the surface hardness of the ball should be measured by a hardness tester equipped with a handheld indicator, which is known as the “hardness tester“ D ””.

The method of testing the hardness is as follows:
Three measurements are performed at points that are at equal distances from each other around the circumference of the ball. Measurements begin in the area of ​​drilling holes of the ball, while the probe of the hardness gage is perpendicular, that is, at an angle of 90 degrees to the surface of the ball. The results of the three measurements are added, and the resulting value is divided by 3. The final value is the hardness of the surface of the ball when measured with a hardness tester "D". All measurements are carried out at room temperature, which can usually be determined by sensations while touching the ball. If you take measurements of hardness immediately after the ball was brought from frost or from a zone with a high temperature, the measurement results will not be accurate.
