Most modern bowling centers display scores automatically on overhead monitors. But knowing how to keep score manually isn't just a party trick — it gives you a deep understanding of why certain frames matter more than others, why doubles are so valuable, and what you need to bowl in the remaining frames to hit a target score. It's the difference between watching your score and understanding it.
The Scorecard Layout
A standard bowling scorecard has 10 boxes — one per frame. Each box has a small upper-right section divided into two sub-boxes for the two balls of that frame. The lower portion of each box shows the running total. Frame 10 has three sub-boxes because you can earn a bonus ball.
The symbols used on a scorecard:
| Symbol | Meaning | Drawn as |
|---|---|---|
| Strike | All 10 pins on the first ball | X (in the right sub-box) |
| Spare | Remaining pins on the second ball | / (diagonal slash) |
| Miss / Error | Failed to knock the remaining pins | — (dash) or the number |
| Split | Two or more pins with a gap, not including headpin | Circle around the first ball count |
| Foul | Crossed the foul line | F |
| Gutter ball | Zero pins | G or 0 or — |
Scoring Open Frames
An open frame is any frame where you don't knock all 10 pins down in two balls. Scoring is simple: add the two ball counts together. That's your frame score. Add it to the running total from the previous frame.
Example: Frame 1 — you knock 7 pins on ball 1, then 2 pins on ball 2. Frame score = 9. Running total = 9. Simple.
Scoring Spares
A spare scores 10 points plus the number of pins you knock down on your very next ball (the first ball of the next frame). This means you can't write the spare frame's total until after you bowl the first ball of the next frame.
Example: Frame 3 — spare. Frame 4 ball 1 — 8 pins. Frame 3 score = 10 + 8 = 18. Add 18 to your running total after frame 2 to get frame 3's cumulative score.
Scoring Strikes
A strike scores 10 points plus the total of your next two balls. This means you can't finalize a strike frame's score until two more balls have been bowled.
Example: Frame 5 — strike. Frame 6 — 8 pins then spare (meaning 2 more pins). Frame 5 score = 10 + 8 + 2 = 20. Note: the spare in frame 6 means frame 6 also gets a bonus, calculated separately.
Scoring Consecutive Strikes
Two consecutive strikes (double): the first strike's score = 10 + 10 + (third ball). You need three balls to finalize the first frame of a double.
Three consecutive strikes (turkey): the first strike scores 30 — the maximum any single frame can score. 10 + 10 + 10 = 30. You can start filling in that frame's total as soon as the third strike is bowled.
The 10th Frame Rules
The 10th frame works differently from all others:
If you bowl a strike on your first ball of the 10th, you earn two additional balls (for a total of three in the 10th). These bonus balls are scored as-is — no further bonuses. The 10th frame total is simply the sum of all three balls.
If you bowl a spare in the 10th (pin count on ball 2 completes all 10), you earn one additional ball. The 10th frame total = 10 + the bonus ball count.
If you bowl an open frame in the 10th (miss the spare), you get no extra balls. The 10th frame total = the two ball counts added together.

| Frame | Ball 1 | Ball 2 | Bonus | Frame Score | Running |
|---|---|---|---|---|---|
| 1 | 8 | / | +7 | 17 | 17 |
| 2 | 7 | 2 | — | 9 | 26 |
| 3 | X | — | +7+2 | 19 | 45 |
| 4 | 7 | 2 | — | 9 | 54 |
| 5 | X | — | +X+8 | 28 | 82 |
| 6 | X | — | +8+1 | 19 | 101 |
| 7 | 8 | 1 | — | 9 | 110 |
| 8 | X | — | +9+/ | 29 | 139 |
| 9 | 9 | / | +8 | 18 | 157 |
| 10 | 8 | 1 | — | 15 | 172 |
