How bowling scoring works
Ten-pin scoring looks tricky only because strikes and spares borrow points from later rolls. Take it one step at a time.
- Ten framesA game is ten frames. Each frame is your turn at a full rack of ten pins.
- Two rolls per frameYou get up to two rolls in a frame to knock all ten pins down.
- Open frameIf pins are still standing after two rolls, the frame scores the number of pins you knocked down.
- SpareClear all ten pins with two rolls and the frame scores 10 plus the pins from your next roll.
- StrikeClear all ten on the first roll and the frame scores 10 plus the pins from your next two rolls. You do not roll again in that frame.
- Tenth frameA strike or a spare in the tenth frame earns bonus rolls inside the frame: two after a strike, one after a spare, for a maximum of three rolls.
- Add as you goEach frame's score is added to the running total once its bonus rolls are known. Twelve strikes in a row make a perfect 300.
| Frame | Rolls | Frame score | Running total |
|---|---|---|---|
| 1 | X (strike) | 10 + 7 + 3 = 20 | 20 |
| 2 | 7, / (spare) | 10 + 9 = 19 | 39 |
| 3 | 9, - (miss) | 9 | 48 |
What is a good bowling score
Good is relative. Someone at a birthday party with house shoes and a house ball is doing well to clear 100, while a regular league bowler will expect a lot more. Rather than comparing yourself with a figure from somewhere else, track your own games here and watch your average move. A rising average is the most honest sign of progress.
How to keep score by hand
| Mark | Meaning |
|---|---|
| X | Strike: all ten pins on the first roll of a frame |
| / | Spare: the rest of the pins on the second roll |
| - | Miss: no pins on that roll |
| F | Foul: the bowler crossed the foul line, so the roll counts as 0 |
| 1 to 9 | Pins knocked down on that roll |
Write a frame's total only once its bonus rolls are known; until then, leave it blank. Press Print blank score sheet for a sheet with six bowlers and ten frames each. If dice are more your thing on game night, the Yahtzee-style score card prints the same way.
Bowling average and handicap
Average is simply total pins divided by games bowled. Enter your game scores in the Average block, or use the games from this session, and the calculator shows the result to one decimal place.
Handicap evens out a league so bowlers of different skill can compete. Leagues set their own base score and percentage, so the Handicap block asks for both rather than guessing. It takes the gap between the base and your average, applies the percentage, rounds down and never goes below zero. Check your league's rules for the numbers to use.
