The Best in Youth Duckpin Bowling!
Average - A bowling average is determined by dividing the bowler's total pinfall in a league by the number of games bowled in that league, dropping all fractions.
Foul - A foul is committed when any part of the bowler's person or clothing touches the foul line or touches any point past the foul line, during or after release of the ball, this shall be considered a foul. If any object falls from the bowler's person and breaks the light beam during or after release of the ball, this shall be considered a foul. If the light beam is not broken, no foul shall be called. Upon notification to a member of the opposing team, a player may cross over the foul line to remove any obstructions. If, for whatever reason, a bowler goes over the line or touches any point beyond the line but does not release the ball, no foul shall be called.
Highest Average - The highest average attained in any one of several NDYA-sanctioned leagues in which the bowler competes.The following NDYA rules apply to all NDYA-sponsored leagues, tournaments, and events. Please refer to the National Duckpin Bowling Congress for actual game rules.
Handicap - Method of equalizing competition. Based on 80% of the difference between bowler's average and 160. For example, 160 minus bowler's average of 65 = 95 x 80% = 76.
Loft - Any ball delivered in anger that, while in the air, passes the furthest ducktail, dot, arrow, or 15 ft.
a. A league must have a minimum of 4 teams. A team may consist of 2, 3, 4, or 5 bowlers. If you have a 6-member team, all 6 bowlers will bowl every game, dropping the low score each game to determine the win or loss.
b. Legal Lineup
Option I - 3 bowlers for a 5-member team, 2 bowlers for a 4-member team, 1 bowler for 3- or 2-member teams. Forfeit is granted to team opposing a team that does not have a legal lineup.
Option II - No team shall forfeit as long as one bowler of that team is present and able to bowl. After 3 weeks, if ony one bowler remains on the team, the team shall be disbanded and the one remaining bowler shall be placed on another team.
Note: Scores rolled by non-NDYA members (i.e., non-sanctioned substitutes, pacers, etc.) do not count for league competition or for awards.
c. Absentee Score
Option I - Use bowler's full average and full 80% handicap.
Option II - Use bowler's average minus 5 pins, plus full 80% handicap.
d. Vacancy Score (Blind)
Option I - Pee Wees - 50, Preps - 60, Bantams - 70, Juniors - 80, and Majors - 90.
Option II - Use the league average, plus full 80% handicap. Add all averages together and divide by the total number of bowlers in the league.
Option III - For Prep/Bantam mixed leagues, use 65 plus full 80% handicap. For Junior/Major mixed leagues, use 85 plus full 80% handicap.
e. Late Members will not be allowed to catch up, but will receive 1/10th of their average (dropping all fractions) per frame for each frame missed, number of pins not to exceed 10 per frame. Such a game will count toward the individual's average and wins/losses. A late bowler may enter a game at any point.
Bowling Shoes - All bowlers must wear bowling shoes. In the event the child's feet are too small for bowling shoes and they deliver the ball from a stationary position, allow them to bowl in rubber-soled shoes. Such shoes should be carried (not worn) into the center on inclement days. Never allow a child to bowl in their socks or bare feet.
Bumper Bowling - At the discretion of the Youth Director, Bumper Leagues may be established for Pee Wees who bowl while gutter bumpers are in place. Bumper leagues are recognized as official NDYA leagues with bowlers being eligible for several individual awards; however, some additional rules apply (see Awards Program for award eligibility):
a. All members of the league will be sanctioned as bumper bowlers whether the bumpers routinely affect their scores or not.
b. At such time a bumper bowler transitions into a regular non-bumper league, the bowler must establish a new non-bumper average before becoming eligible for awards and before their scores count toward team competition.
a. The deadwood must be removed from the playing surface (lane) and gutters after each ball is rolled, mechanically if possible. Any pin (or pins) falling after the bowler activates the reset mechanism and/or any pin (or pins) knocked down by or falling after the action of the reset mechanism of an automatic pinsetting machine, shall not count as down. Failure to remove deadwood or balls from the playing surface (lane) or gutters will be ruled as follows:
First Ball - The first ball is lost. All pins knocked down by the first ball are respotted and the bowler rolls a second and third ball.
Second Ball - The second ball is lost. All pins knocked down by the second ball shall be respotted and the bowler rolls a third ball.
Third Ball - The third ball is lost. All pins knocked down by the third ball are lost and the bowler is through for that frame.
b. When an automatic pinsetting machine is in use, and the Number 7 pin and/or the Number 10 pin is knocked down by pins being cleard by the gutter belt, such pin(s) shall be regarded as down so long as the deadwood or reset mechanisms have not been activated. Any pin or pins knocked down by the Number 7 pin and/or the Number 10 pin as a result of this action, shall also be counted as down.
Disputes - Any match that is under dispute must be made known to the opposing team captain and official in charge. Play should not being until dispute is clarified and satisfied. Should the players on the protesting team roll the next ball before the protest is made, no protest shall be given consideration.
Foul Line Rules - All fouls shall be handled in accordance with the following rules:
a. When a foul occurs on the first ball, the ball is declared dead, all pins shall be respotted, and the bowler rolls his second and third balls. If the bowler knocks all ten pins down on the second ball it shall be counted as a spare.
b. When a foul occurs on the second ball, all pins knocked down by the second ball shall be counted as though knocked down by the third ball and the bowler is through for that frame. If the bowler spared on the second ball and fouls, it is scored as a ten frame and the bowler is through for that frame.
c. When a foul occurs on the third ball, all pins knocked down by the third ball are lost and the bowler is through for that frame.
d. Should a bowler make a strike in the 10th frame and foul on the first roll-off ball, that ball shall be lost and the pins knocked down by that ball counted as though knocked down by the second roll-off ball. Should a foul occur on the second ball, both the ball and the pins knocked down by that ball are lost, and only the pins knocked down by the first ball count.
e. If it is apparent that a player deliberately fouls to benefit by the calling of such foul, the bowler shall receive a zero for that frame. Where an automatic pinsetting machine is in use and it is apparent that a bowler deliberately steps on the pedal or pushes the button that activates the deadwood removal mechanism to benefit by such action, then the act of the bowler shall be considered a deliberate foul, recorded as such and bear the same penalty as outlined in foregoing paragraphs.
f. Bowlers shall show lane courtesy to bowler(s) on an adjacent lane who is ready to start or in their approach. Bowlers shall make every effort to bowl ball for ball (start approach as soon as the other bowler(s) on the adjacent lane(s) has completed their delivery). Any bowler who waits for the bowler(s) two or more lanes away shall be deemed to have committed a deliberate foul and shall receive a zero for that frame.
NOTE: The above foul rules shall be used for both manual and automatic machine pinsetting.
a. A ball must hit a pin before leaving the playing area. If said ball returns to playing area and knocks down pins, such pins are counted as down. If a ball does not hit pins upon delivery, rebounds and knocks down pins, such pins must be reset.
b. If the first ball rolled rebounds from gutter and knocks down pins, the pins must be reset and two balls are then rolled.
c. If the second ball rebounds from the gutter, the pins knocked down by the second ball must be reset and the third ball is rolled.
d. If the third ball rebounds from the gutter, only the pins knocked down by the first and second balls are counted.
Inclement Weather - If inclement weather or other extenuating circumstances make it necessary to cancel league competition, a fun day should be substituted for those in attendance. Bowlers should be notified that scores are not eligible for awards.
a. The lanes immediately adjoining each other shall be used in all games. The contesting team shall successively and in regular order roll one frame on the one lane, and then change lanes for the next frame, alternating lanes each frame until the game is completed. The teams must start the following game on the same lanes on which the 10th frame of the previous game was rolled.
b. At the option of the league, two frames may be rolled consecutively on one lane by each bowler on the team before alternating lanes. Where this procedure is followed, the teams will start each succeeding game on the opposite lane from which the 10th frame of the previous game was rolled.
Pre-Bowling - Individual
a. At the discretion of the Program Director and the center's management, bowlers may roll in advance of their scheduled match. Such games must be rolled under league conditions and strict ADULT supervision.
b. Individual awards WILL NOT be recognized for pre-bowled games. Please make the bowler and their parents/guardians aware of this prior to their pre-bowling.
c. A bowler may not roll his games for a previous league session.
Pre-/Postponed Bowling- Team
a. At the discretion of the Program Director and the center's management, team matches may be rolled in advance or postponed. If granted, pre-bowled matches must be agreed upon by all members of both teams and be rolled under league conditions and strict ADULT supervision. If granted, such postponements should be rolled off within 3 weeks of the date of the postponement and be rolled under league conditions and strict ADULT supervision.
