Chapter I General Rules of the Game

Rule 1. Game - Definition
The game of bowling in the ten pins system consists of ten frames. The player throws two balls in each of the first nine frames, unless the strike is the first strike. In the tenth frame, a player throws three balls if a strike or a spin is counted. Each frame should be completed by the player in the usual order.

NOTE: For team competitions in the Bakker system, each player in the team performs all consecutive ball shots in one game until all ten frames are completed.

The correct sending of the ball is a throw at which the ball leaves the place where the player is located and crosses the line of foul on the game track. A score is counted for each throw, unless an "erroneous sending of the ball" is claimed. The throw of the ball must be done only by hand. You can not use any devices that are attached or applied to the ball, which can perform an auxiliary function on the throw or are a moving part during the throw.

Rule 2. Game - scoring points
Except when a strike occurs during the first throw, the number of pins shot down by the player at the first throw of the ball is marked in a small square in the upper left corner of the corresponding frame on the monitor, and the number of pins shot down by the player with the second ball throw is marked in the box in the upper right corner of the frame. If none of the pins in the frame are knocked down during the second throw of the ball, a dash (-) is placed in the scoring field. The total score for two attempts is counted and displayed on the monitor immediately.

Rule 3. "Strike"
If at the first throw of the ball in the frame the entire set of set pins are knocked down, then the strike is counted. The strike is marked with the 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 down by the player for the next two ball throws.

Rule 4. "Double"
Two consecutive strikes are called doubles. 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 triples. 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 beat out consistently 12 strikes.

Rule 6. "Spare"
Spae is counted if the pins remaining to stand after the first throw of the ball are knocked down at the second throw of the ball in this frame. The spin is indicated by the sign (/) in the upper right corner of the corresponding frame. In this case, 10 points are awarded for the spade plus the number of pins shot down by the player on the subsequent throw of the ball.

Rule 7. Clear frame
If the player does not manage to knock down all 10 pins for two ball throws in one frame, this is called an open frame, unless the pins that continue to stand after the first throw of the ball form a "split".

Rule 8. "Split"
Split is the position of several pins left standing after the first throw of the ball, in which the first (head) pins fell and:

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

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

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

Rule 9. The style of the game
The game is played on two tracks (one pair), adjacent to each other. Members of competing teams, troikas, couples or independent players must compete in the same order in a single frame on a single track in the usual way, and for the next frame move to another track until five pairs are played on each of the two tracks.

NOTE: for team games on the Bakker system, the members of the competing teams, the trio and the pairs play bowling sequentially and in the appropriate order and consecutive frames in the same game. Teams must change paths within a couple of ten frames.

Rule 10. Correct knocking down pins
A throw of the ball is considered perfect when the player sent the ball and this ball crossed the foul line. Each ball roll is counted, unless the ball is declared to be erroneous. The throw of the ball must be carried out only by hand. It is forbidden to use any devices in the ball itself or attached to it, which are disconnected after the throw, or which move during the throw.

NOTE: A player may use special equipment to assist in capturing and throwing a ball if it replaces an amputated or disabled hand completely or its main part.

It is believed that the player knocked down pins correctly, if the following conditions are met:
The skittles fell or flew off the ground under the action of a ball or some skittles.
The skittles fell or flew off the platform by the action of skittles bouncing off the side wall or the tailboard.
The skittles fell or flew off the ground under the action of skittles bouncing off the cleaning board when it was on the ground before cleaning the knocked pins.
Skittles that bent and leaned against the wall of the hammer or side panel.

All such pins are considered knocked down and must be removed from the site until the next throw of the ball.

Rule 11. Incorrect (unauthorized) knocking down of pins
If one of the following events occurs, the ball roll is counted, and the subsequent knockdown is not:
The ball goes out of the path to reach the pins.
The ball bounces off the tailgate.
The skeleton bounces off after contact with the body, hands or feet of the person in charge of setting the pins.
There is contact between the skittles and the mechanical pin setting device.
Any pin falls when you remove the knocked-out pins.
Any pin falls when contacting the person in charge of setting the pins.
The player breaks the rules.

The throw of the ball is carried out when the knocked down bowls are not removed from the track or from the gutter and the ball touches these knocked pins before leaving the track surface.

If an incorrect pin-down occurs and the player is eligible for additional ball shots in the given frame, the misfired pin or skittles should be set to the place where they originally stood.

Rule 12. Skittles - wrong installation
If, during the first or second throw of the ball, immediately after the throw, it is found that one or more pins are incorrectly installed, but all the necessary pins are available, this ball throw and the corresponding result are counted. The responsibility for determining the correctness of the installation of the pins lies on the player itself. Before casting, a player who has noticed an incorrect setting of the pins must insist on their proper installation, otherwise the initial setting of the pins will be considered correct.

It is forbidden to change the position of any pins left standing after throwing the ball. This means that if the pins are moved by the mechanical pin setting device, then they must stay in their new place and their manual permutation is prohibited.

Rule 13. Skittles - bounce
If there was a bounce of the pins, and they stayed on the track, then these pins are considered not knocked down.

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

Rule 15. Skittles - replacement
In the event of breakage or other damage to skittles during the game, this pin must be replaced by another, the condition and weight of which is as close as possible to the other pins from the kit used. The need to replace pins is determined by the officials of this tournament.

Rule 16. The wrong ball
The ball is declared erroneous in any of the following cases:
Immediately after the ball is thrown (and until the next ball is thrown in the same path), it turns out that one or more of the pins are missing from the kit.
The person in charge of setting the pins will touch any standing pins before the ball darts to the pins.
The person in charge of setting the pins removes or touches any fallen pins before it stops.
The player rolls the ball off the wrong track or in turn. Or one player from each team on a pair of tracks is sending the ball out of its path.
The presence of physical interference by another player, spectator or moving object or the person in charge of setting the pins, while the ball is being cast and before it is completed. In this case, the injured player can either agree with the result of this throw, or declare that the ball is wrong.
Any pin moves or falls during the sending of the ball, but before the ball reaches the pins.
The sent ball hits a foreign object.

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

Rule 17. A throw of a ball on a wrong path (for official competitions)
NOTE: in accordance with the rules of the ETBF and the Federal Security Service, all official competitions are held in a sports mode (league system), two, three or four participants compete on one pair of tracks (the number of participants performing on one pair of tracks can not change during one competition) ;

Each game is played by the participants on a pair of tracks.

After one, two games (no more), all participants on the referee's command switch to other pairs of tracks.

When a ball is declared incorrect, the player or players must roll on the correct track in the following cases:

One player throws the ball on the wrong path.

One player from each team on a pair of tracks throws the ball on the wrong track. If several players from the same team in turn throw the ball on the wrong track, then this frame will be finished without changes. All subsequent frames must begin on the correct path.

Rule 18. Definition of a foul (violation)
A foul is fixed if the player moves or fades over the foul line by any part of his body, and also touches any part of the track, equipment or structure during or after the ball is thrown.

A ball is considered to be in the game until the same or another player takes a place to make the next throw of the ball.

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

Rule 20. Calculation of violation of rules during the roll
When fixing a violation (foul), the throw of the ball is counted, but the pins shot down with this throw are not counted. If the player who committed the foul has the right to additional ball throws in this frame, the pins hit by the ball when registering a foul must be reinstalled.

Rule 21. An obvious foul
Foul is fixed, even if it is not determined by an automatic foul recording device or by a judge, but the foul is evident for the following persons:

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

For officials watching 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 in the following cases:

It is proved that there are failures in the operation of the automatic device for recording a foul.

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

NOTE: as evidence, cinema and video shooting can be used, but only if the main judge of the competition is notified about the protest before the next player rolls out in this game 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 can not serve as grounds for filing a protest and / or appeal. In the above, the situation regarding the protest must be immediately notified to the chief judge of the competition, protests are taken only from players and / or their official representatives.

Rule 23. The Conditional Ball
In the case of filing a protest, the object of which is a foul, the correct fall of the pins or the wrong ball, and which can not be immediately resolved by the officials responsible for conducting the tournament, the player must drop the conventional ball or replay the frame.

In the event of a controversial situation at the first throw of the player in any frame, or at the second throw of the 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 fouls or not, this player must complete the frame, and then throw the conditional ball into a pin arrangement that would have stood if the contested skittles had not fallen.

If the subject of the dispute is a dubious incorrect drop in the size of the pins, the player must complete the frame, and then drop the conventional ball into a pin arrangement that would stand if the contested skittles did not fall.

If the controversial situation is resolved, regardless of whether the ball was to be declared wrong or not, the player must complete the frame, and then play the controversial frame completely.

If the dispute arises in an additional attempt or in the third roll of the tenth frame, then the disputed ball is not assigned unless the disputed situation has been resolved regardless of whether the ball was to be declared wrong or not. In this case, the conditional ball should be thrown into the same pin arrangement, which stood when the ball was thrown, which became the subject of a dispute.

Rule 24. Ball - change the surface
Change 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 the rule was violated, is subject to cancellation. In addition, the player is excluded from further participation in these competitions. Under the competition is understood the rest of the current game and all subsequent games of the tournament.

Rule 25. Foreign objects in the approach area
The application of any foreign matter to any part of the playing area, which adversely affects the normal playing conditions of other players, is prohibited. This rule extends, but is not limited to, such substances as talcum, pumice and resin on shoes, soft soles or heels leaving traces in the approach zone. Do not pour talc powder into the playing area.

NOTE: The zone for players (the play area) must be determined by the organizers of the competition and approved by the main referee using the identification methods that are understandable to the spectators. 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 (an accredited coach or team leader), unless otherwise specified.

Rule 26. Errors in Account Management
Errors in the conduct of an account or the calculation of the result must be corrected by the responsible person of the tournament immediately after finding the fact of such an error. Disputable situations should be resolved by a specially authorized person.

Protests for errors in the conduct of the account must be submitted no later than one hour after the end of the game or block of games of each day of the tournament, but before the delivery of prizes or the start of the next round (in a knockout game), whichever occurs first.

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

NOTES: After registering an account, it can not be changed unless an obvious error has been committed while maintaining the account and calculating the score. Obvious errors must be corrected by the tournament official immediately after they are discovered. Decisions on controversial situations are made by the leadership of the tournament. In accordance with the rules, tournament management can set a fixed deadline for correcting mistakes. 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.

Глава II Спецификация оборудования

1.12 Pin setting devices (pinsetters)
Bowling centers that use automatic pin setting devices must ensure that they are checked annually to determine the correct placement of the pins. In case of detection of deviations in the operation of the pin setting devices, the approval of such devices will be made only after all the deficiencies have been removed.

1.13 Bumpers
The baffle or side partition can be entirely made of hardwood or from tested and approved synthetic materials. They must be installed parallel to the track.

The bump stop should start from the point opposite or not more than 15 inches (381 mm) in front of the position for the pins # 1 and pass to the rear shock absorber wall.

The distance between the wooden surface of the two bumpers should be 60 1/8 inches ± 1/8 inches (1527 ± 3 mm).

The height above the track surface should be 20 1/2 inches ± 3 1/2 inches (521 ± 89 mm).

For tracks equipped with automatic pin setting devices, this width must be at least 25 inches (635 mm). The mine zone specifications for automatic pin setting equipment are developed specifically for a specific pin setting device simultaneously with the issuance of approval for its application.

1.15. Rear shock absorber
The rear shock absorber should always have a coating of black material. In this case, the design of the rear shock absorber should be such that it prevents the rebound (rebound) of skittles on the track.

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

a) At each of the following points in the approach section (the distance is measured up to the line of the spade), up to 7 guiding landmarks can be inserted or plotted: 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 points should be parallel to the line of attack (foul), and each guideline should be uniform, in the form of a circle whose diameter should not exceed? inch (19 mm).

b) At a point 6-8 feet away (1828-2438 mm), up to 10 guide points can be inserted or applied along the line of the spinal line and parallel to it on the track. Each guiding reference should be uniform, in the form of a circle whose diameter should not exceed? inch (19 mm).

c) At a point 12-16 feet (3658-4877 mm) after the line of spacing on the track, up to 7 targets can be inserted or plotted. Each goal must be uniform, and can consist of one or more arrows, rhombuses, 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 should be located at an equal distance from the other, and together they should form a single picture.

d) Inserted markings or signs should be made of wood or plastic. They must be flush with the surface of the approach sections. When marking, it should be done on the hardwood, after which the markings should be covered with varnish or similar, transparent material that is usually used for finishing the surface. 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 authorized by the Federal Security Service, the following requirements must be applied to the processing of tracks.

After each application of the air conditioner, at least 5 units of the air conditioner must remain on the lubricated part of the track (including any part of the track treated with the buffer of the air conditioning machine). On the entire surface of the lubricated part of the tracks it is necessary to use an air conditioner of the same type and manufacturer. When carrying out competitions to lubricate the tracks, the same air conditioner and the same treatment methods should be used.

The minimum and maximum processing distance, including the portion of the track treated with the buffer, must be at least 28 feet (8535 mm) and not more than 45 feet (13715 mm). This rule does not mean that the recommended minimum treatment distance is 28 feet. To process the tracks, you can take any value from the range of 28 to 45 feet.

3. Specification of bowling pins

4. Specification of bowling balls

4.1 Material
A standard bowling ball must be made of non-metallic composite material and must meet the specifications of weight, size and balance specifications.

The use of mobile devices in a bowling ball is prohibited, except that it is permissible to insert any device to change the distance between the fingers or the size of the thumb holes and other fingers, provided that such a design of this device ensures its rigid fixation during the throw, and It can not be removed from the ball without damage. . On the entire surface of the lubricated part of the tracks, one type of grease and the manufacturer must be used. When carrying out the competition, the same lubricant and the same treatment methods should be used to lubricate the tracks.)

It is forbidden to insert a ball of metal or any other substance different from the source material of the ball used in its manufacture. In addition, any change in the ball leading to the exit of its weight parameters or balancing beyond the range specified in the specifications is not allowed, and the use of such balls in competitions held under the auspices of WTBA is strictly prohibited.

To pierce the holes of the ball can be inserted special plugs. It is allowed to insert into the ball various indicators, markings, provided that they are flush with the outer surface of the ball. In all cases, they must be made of a material of a similar (though not necessarily the same) source material of the ball. The outer surface should not have any foreign material.

These restrictions also apply to both the manufacture and / or any refinement of the ball, provided that this does not apply to deliberate overstating of the weight during the ball making process, installation of inserts or qualified repairs.


4.2 Weight and size
The ball's circumference and weight should not exceed 27 inches (686 mm) and 16 pounds (7.25 kg), respectively. The diameter of any ball should be constant.

On the surface of the ball there should be no depressions or grooves, with the exception of holes or recesses for its capture, identification inscriptions and numbers, accidental chips or spots of wear.

4.3 The parameters to be measured at the venue:


a) Gross weight. Should not be more than 16 pounds (7.25 kg).

b) Holes or grooves for gripping. Their number should not exceed 5 (five).

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

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

e) One opening for inspection is allowed. Its diameter should not exceed 5/8 inches (15.9 mm) and depth - 1/8 inch (3.2 mm).

f) Static imbalance. Do not exceed the tolerances specified below.

g) Hardness of the ball. In accordance with the requirements listed below.


4.4 Parameters that do not need to be measured at the tournament venue:

a) The length of the circle of bowling balls

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

NOTE: The hardness of the surface of the ball should be measured by a hardness meter equipped with a manual indicator, which is known as the "hardness tester" D "".

The hardness testing procedure is as follows:
Three measurements are made at points equidistant from each other along the circumference of the ball. The measurements begin in the hole drilling area of ​​the ball, while the hardness probe 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 value obtained is divided by 3. The final value is the hardness of the ball surface when measured with a hardness meter "D". All measurements are taken at room temperature, which, usually, can be determined by the sensations during the touch of the ball. If you perform hardness measurements immediately after the ball has been brought from a frost or from a zone with a high temperature, the measurement results will not be accurate.
