How a spare changes the next calculation

The next ball matters; the next whole frame does not.

Write the spare correctly

A spare means the two deliveries in a frame total ten pins. Seven then three is written 7/. The slash represents the pins remaining after the first delivery, not a fixed number of pins. A 2/ spare and a 9/ spare both begin with ten frame points before the next-delivery bonus is known.

Work an example

Suppose frame one is 7/ and frame two is 52. Frame one scores ten plus five, or fifteen. Frame two is open and scores seven. The cumulative total after frame two is therefore 22. The second delivery of frame two does not enter the spare bonus because that bonus uses only the next delivery.

Follow consecutive spares

If frame one is 7/, frame two is 8/ and frame three starts with six, frame one scores eighteen and frame two scores sixteen. The cumulative total after frame two is 34. Frame three’s six is used for frame two’s bonus and will also be included in frame three’s own calculation. Keep frame points beside cumulative points to avoid mixing them.

Handle the final spare separately

A spare in the tenth frame earns one fill delivery to complete that frame’s scoring. Enter 7/5 for seven, spare and a five-pin fill ball. That tenth frame is fifteen points. It does not create an eleventh frame. If the fill ball is a strike, enter X and add ten; the fill strike does not earn another fill delivery.
