Bowling Varieties and Scoring Systems
Types of Bowling
1. Tenpin Bowling
The most common form of bowling and the standard for international competitions.
Pin Arrangement: 10 pins in a triangular formation (1-2-3-4 pattern).
Ball Specifications:
- Diameter: ~8.5 inches
- Weight: 4 to 16 lbs (~1.8-7.3 kg)
- Features: Three finger holes for grip, made of rubber, resin, or composite materials.
2. Duckpin Bowling
Originating in the late 19th century in the U.S., primarily popular along the East Coast (e.g., Maryland, Connecticut). The name comes from the short, stubby pins resembling ducks and their wobbling motion when hit. Evolved from ten-pin bowling but uses smaller balls and pins, making it more challenging.
Pins: 10, shorter and thicker than ten-pin pins, arranged in the same pattern.
Ball: No finger holes, ~4.75 inches (12 cm) in diameter, max weight 3 lbs 12 oz (~1.7 kg).

②Candlepin Bowling
·Features tall, thin pins resembling candles.
·Uses the smallest ball (only 2.5 lbs).
·Allows 3 throws per frame.
·Popular in New England, U.S.
③Fivepin Bowling

Scoring Methods
1. Tenpin Bowling
①Game Structure: 10 frames, max 2 throws per frame (unless a strike is scored).
②Strike ("X"): Knocking down all 10 pins on the first throw → 10 points + next two throws as bonus.
Example:
Strike in Frame 1, then 7 pins in Frame 2 → Frame 1 score = 10 + 7 = 17.
③Spare ("/"): Knocking down all 10 pins in two throws → 10 points + next throw as bonus.
Example:
Spare in Frame 1, then 5 pins in Frame 2 → Frame 1 score = 10 + 5 = 15.
④Open Frame: Failing to knock down all 10 pins → only counts pins fallen.
⑤The 10th Frame Rules:
Strike: Extra 2 throws.
Spare: Extra 1 throw.
⑥Perfect Game: 12 consecutive strikes (300 points).
2. Duckpin Bowling
①3 throws per frame (instead of 2).
②No strike/spare bonuses – only counts pins knocked down.
③Theoretical max score: 300 (30 per frame), but extremely rare.
④Simpler scoring: Only tracks pins per frame and cumulative total.
This scoring system reduces strategy but increases unpredictability, making the game more entertaining.
Bowling offers diverse experiences, from the competitive ten-pin to the quirky duckpin and regional variants like candle-pin and five-pin. Whether for sport or fun, each style provides unique challenges and enjoyment for players of all levels.
