Ten-pin bowling looks simple on the surface, yet the score sheet can feel like a puzzle until you understand the value of each frame. One of the biggest sources of confusion is the spare.

Below is a clear breakdown of what a spare is worth, how to calculate it on any frame, and why learning to convert spares is the quickest path to a higher average.

Bowling Scoring in a Nutshell

A standard game has ten frames, and every pin you knock down contributes to your total. Most frames allow up to two rolls, except the tenth, which can award a bonus roll for a strike or spare.

Strikes and spares add bonus points from rolls that follow. That bonus structure is what gives bowling its strategic twist and what makes spares more valuable than many beginners assume.

What Exactly Counts as a Spare?

A spare occurs when you knock down all ten pins across the two rolls of a single frame. In scoring notation it is marked with a forward slash "/" on the second roll.

Unlike a strike, where the pins fall on the first roll, a spare shows you needed both attempts, yet you still cleared the deck. Because you succeeded in the frame, the rules award a bonus on top of the base ten pins.

The Math Behind Spare Scoring

When you record a spare, that frame’s score is 10 plus the number of pins knocked down on your very next roll. Only one roll is used for the bonus, not the next two.

This means a spare is worth anywhere from 10 points, if your next roll is a gutter ball, up to 20 points, if your next roll is a strike that knocks down all ten pins.

Spare Scoring Examples

Example 1: You hit 6 pins on your first roll and pick up the remaining 4 for a spare. On the next frame’s first roll you knock down 7 pins. The spare frame scores 10 + 7, giving you 17 points.

Example 2: Same spare, but your next roll is a strike. Now that spare frame is worth 10 + 10, totaling 20 points.

Example 3: You spare in the tenth frame. Because there is no eleventh frame, the rules grant a single bonus roll. Whatever you hit on that roll is added the same way, so a strike would again give the full 20.

Strings of Spares and Their Effect

Rolling spares in back-to-back frames creates a steady stream of bonus points. Each spare feeds off the first roll of the frame that follows, so a series of consistent first-ball counts keeps every prior frame climbing.

For instance, four consecutive spares followed by first-ball counts of eight would add 18, 18, 18, and 18 to the score sheet, a reliable way to post a solid game even without strikes.

Spare vs. Strike: Key Differences

A strike is 10 plus the next two rolls, so its ceiling value can hit 30, whereas a spare caps at 20. Because of that extra roll, strikes carry more scoring potential.

Still, spares are easier to achieve on average, and missing them turns a frame into a simple pin count with no bonus. In competitive play, the bowler who never misses makeable spares often outscored the one chasing strikes but leaving open frames.

Tips to Convert More Spares

Raising your spare percentage is the fastest way to lift your average. Start by using a plastic or polyester ball for straight throws. A ball that hooks less is easier to aim at corner pins.

Second, develop a specific target for every common leave. The 7, 10, and bucket formations all have optimal angles that minimize deflection and improve carry.

• Practice shooting at a single pin for a full game to build muscle memory
• Keep your heel on the approach longer to maintain balance and accuracy

Conclusion

A spare guarantees 10 points plus the pins from your next roll, giving it a flexible value between 10 and 20. Because those bonus points hinge on the following frame, every roll matters.

Mastering spare conversions transforms your consistency and sets the foundation for bigger scores when the strikes start flowing.
