Duckpin bowling has rules<ref name=NDBCrules2014>{{cite web |title=Rule Book/ Directory |url=http://www.ndbc.org/pdf/ndbc-rule-book-13-14.pdf |website=ndbc.org |publisher=National Duckpin Bowling Congress |archive-url=https://web.archive.org/web/20180821121729/http://www.ndbc.org/pdf/ndbc-rule-book-13-14.pdf |archive-date=August 21, 2018 |date=September 1, 2014 |url-status=live }}</ref> similar to ten-pin bowling. In a 10-frame game, bowlers try to knock down pins in the fewest rolls per frame. Bowlers have three balls per frame, instead of two as in ten-pin bowling, to knock over a set of 10 pins. If a bowler knocks down all 10 pins with their first roll in a frame, it is scored as a ''[[Strike (bowling)|strike]]''. If all the pins are knocked down in two rolls, the bowler has made a ''[[spare (bowling)|spare]]''. If all the pins are knocked down in three rolls, it is scored as a ''ten'', as in candlepins, with no bonus. If pins are still standing after the third ball, the bowler gets one point for each pin knocked down.

In the case of a strike, the bowler gets 10 points plus the total number of pins knocked down with the next two balls rolled, for a maximum of 30 points. In the case of a spare, the bowler gets 10 points plus the number of pins knocked down with the next ball, for a maximum of 20 points. If it takes three balls to knock down all 10 pins, the bowler gets 10 points, with no bonus. A bowler's final score is the sum of the points earned over 10 frames (a spare or strike in the tenth frame earns one or two rolls respectively). The maximum possible score of 300 points, which is accomplished by rolling 12 strikes in a row, has never been achieved under official conditions.

Duckpin bowling lanes are the same size as ten-pin bowling lanes, but with smaller gutters.<ref>{{cite web |title=Rules of the Game |url=http://www.duckpins.com/rules.htm |website=duckpins.com |access-date=12 August 2021}}</ref>
