Bowling score calculator and score sheet
Scores follow the standard ten-pin rules published by the United States Bowling Congress (USBC). For information only. Not affiliated with or endorsed by USBC or any bowling center. A foul scores 0 pins for that roll: tap 0.
How is bowling scored on a bowling score sheet?
A bowling game has 10 frames, and each frame lets you roll up to two balls at ten pins. An open frame scores the pins you knock down. A spare adds the next roll as a bonus, and a strike adds the next two rolls. A bowling score calculator totals this for you.
The scorecard above follows that rule as you tap. A frame total stays blank until every roll it depends on has been bowled. That is why a strike can look unscored for two more rolls: its value is 10 plus whatever you knock down next.
| Result | Symbol | Frame score | Needs |
|---|---|---|---|
| Open frame | number or - | Pins knocked down | Nothing extra |
| Spare | / | 10 + next roll | 1 more roll |
| Strike | X | 10 + next two rolls | 2 more rolls |
A dash means you missed all the pins on that ball. Scores run as a total from frame to frame, so each frame shows the running total, not just its own points.
How to score bowling strikes and spares
A strike scores 10 plus the pins from your next two rolls, and a spare scores 10 plus the pins from your next one roll. A strike followed by 7 and 2 is worth 19 in that frame. A spare followed by 5 is worth 15. Open frames score only the pins you knocked down.
Here is a short worked example from the first four frames of a game:
| Frame | Rolls | Working | Running total |
|---|---|---|---|
| 1 | X | 10 + 7 + 3 | 20 |
| 2 | 7 / | 10 + 9 | 39 |
| 3 | 9 - | 9 + 0 | 48 |
| 4 | X | 10 + 0 + 8 | 66 |
Frame 1 is a strike, so it adds the next two rolls (7 and 3) to make 20. Frame 2 is a spare, so it adds only the next roll (9) to make 19. Back-to-back strikes make bonuses overlap: three strikes in a row score 30 for the first one. The sample game loaded in the calculator uses these exact frames and finishes on 167.
How does bowling scoring work in the 10th frame?
In the 10th frame you earn bonus balls if you mark: a strike gives you two extra rolls and a spare gives you one extra roll. If you leave the frame open, you get just two rolls. The total is simply the pins from all rolls in the frame, up to three balls and 30 points.
The 10th frame has no later frame to borrow bonus rolls from, so the extra balls are bowled inside the frame itself. The pins are reset after a strike or a spare, so the bonus ball is thrown at a full rack. After a strike, the second ball is also at a full rack. If it leaves pins standing, the third ball is at what remains.
- X X X: three strikes, 30 points for the frame.
- X 7 /: a strike, then a spare on the two bonus balls, 20 points.
- 9 / 5: a spare plus one bonus ball, 15 points.
- 8 1: open frame, 9 points, no bonus balls.
The calculator handles this for you: after a mark in frame 10 the pad stays active for the extra roll, and its top button switches between X and / depending on how many pins are standing.
What is the highest possible score in bowling?
The highest possible bowling score is 300, a perfect game of 12 strikes in a row. Nine frames of strikes plus three strikes in the 10th frame make 12 rolls. Each of the first eight frames scores 30, frame 9 scores 30, and the 10th frame scores 30 as well.
Under the score line, the calculator shows the maximum score you can still reach from your current rolls, assuming you knock down every pin standing on each remaining roll. A new game shows 300. After one open frame the ceiling drops, and you can see exactly how much a single miss costs.
For a quick comparison, tap the perfect game chip (300), the all-spares chip (150, from 5 and 5 in every frame with a 5 bonus ball) or the Dutch 200 chip (alternating strikes and spares for exactly 200). Wondering about averages or percentages across games? Try the percentage calculator.
Frequently asked questions
How do you score a strike in bowling?
A strike is all ten pins on the first ball. It scores 10 plus the pins from your next two rolls. Until those two rolls are bowled, the frame total stays blank, then it fills in on the scorecard.
How do you score a spare in bowling?
A spare means you clear the pins in two balls. It scores 10 plus the pins from your next single roll. A 6 and a 4 followed by a 7 on the next frame is worth 17 for the spare frame.
Why is my frame score blank?
Strikes and spares borrow pins from later rolls, so their totals cannot be known yet. A strike needs two more rolls and a spare needs one. Keep tapping and the blank frames fill in automatically.
What is a perfect bowling game?
A perfect game is 12 strikes in a row for a score of 300. That is nine strikes in the first nine frames and three strikes in the 10th frame, since a strike there earns two bonus rolls.
How many bonus balls do you get in the 10th frame?
A strike in the 10th frame earns two bonus balls, and a spare earns one. An open 10th frame earns none, so you roll two balls. You can roll at most three balls in that frame.
What happens on a foul?
Under USBC rules a foul scores no pins for that delivery, and a foul on a first ball means all ten pins are respotted with only one delivery left in the frame. In this calculator, tap 0 for a fouled ball.
How do I fix a wrong tap?
Press Undo to remove the last roll, as many times as you need. Press New game to clear the whole card and start from frame 1.
Can this bowling calculator score more than one bowler?
This card scores one game at a time. Press Copy score to save a finished game, then press New game for the next bowler. Nothing leaves your device.
