Official Scoring Explained Simply
If you are new to bowling, the official scoring system can look confusing at first.
A strike is not just 10 pins.
A spare is not just 10 pins either.
That is because traditional bowling scoring includes bonus points based on what you do with your next shots.
Once you understand the basic rules, it all becomes much easier to follow.
When you are ready to measure shot quality as well as pinfall, compare the traditional system with KB Scoring.
Official Bowling Scoring Explained in Three Simple Rules
Once you understand these rules, the traditional scoring system becomes much easier to follow.
For a more detailed explanation, read on below.
How Official Bowling Scoring Works
A game of tenpin bowling has 10 frames.
You get 2 balls to try to knock down all 10 pins.
Your score depends on whether the frame is:
- an open frame
- a spare
- a strike
Each one is scored differently.
Some frames are not fully scored until the next ball — or even the next two balls — have been bowled.
Open Frame
An open frame is when you do not knock down all 10 pins with your two shots.
This is the simplest part of bowling scoring.
Your score is just the total number of pins knocked down.
Example
First ball: 6
Second ball: 2
Frame score = 8
Open Frame = Total pins knocked down
Spare
A spare is when you knock down all 10 pins using both balls in the frame.
A spare scores:
10 + your next ball
Example
Frame 1: 7 and 3 = spare
Next ball: 8
Frame 1 score = 18
So a spare gives you 10 pins plus bonus pins from your next shot.
Spare = 10 + next ball
Strike
A strike is when you knock down all 10 pins with your first ball.
A strike scores:
10 + your next 2 balls
Example
Frame 1: strike
Next two balls: 8 and 1
Frame 1 score = 19
This is why strikes are so valuable. They give you the biggest bonus in traditional scoring.
Strike = 10 + next 2 balls
Why Strikes Matter So Much
In official bowling scoring, strikes can raise your score very quickly.
Because each strike includes the next two balls as bonus points, throwing strikes back-to-back has a huge impact.
Example
Frame 1 = Strike
Frame 2 = Strike
Frame 3 = 7 and 1
Frame 1 Score = 10 + 10 + 7 = 27
Frame 2 Score = 10 + 7 + 1 = 18
This is why a player with more strikes can score much higher, even if the total number of pins knocked down looks similar.
The 10th Frame
The 10th frame works a little differently from the first 9 frames.
Normally, you get 2 balls in a frame.
But in the 10th frame:
- bowl a spare and you get 1 extra ball
- bowl a strike and you get 2 extra balls
This makes the 10th frame so important.
Example
7 and 3 in the 10th = 1 extra ball
Strike in the 10th = 2 extra balls
That is why the 10th frame can sometimes include 3 shots instead of 2.
What Is the Maximum Score in Bowling?
The highest possible score in tenpin bowling is 300.
To bowl 300, a player must throw:
12 strikes in a row
That means:
- 1 strike in each of the first 9 frames
- 3 strikes in the 10th frame
Perfect Game = 12 strikes = 300
A perfect game is one of the biggest achievements in bowling.
A Simple Scoring Example
Here is a quick example of how official scoring works over a few frames.
Example
Frame 1: 8, 1 = 9
Frame 2: 6, 4 = Spare*
Frame 3: 5, 2 = 7
Frame 4 = Strike**
Frame 5: 3, 4
*Frame 2 Score = 10 + 5 = 15
**Frame 4 Score = 10 + 3 + 4 = 17
Key Idea
Not every frame is scored immediately.
