Candlepin bowling is a regional variation popular in New England and Eastern Canada. Key differences from ten-pin bowling: smaller balls (no finger holes, ~2.7 lbs), taller thinner pins (candle-shaped), 3 balls per frame instead of 2, and fallen pins are not cleared between balls (deadwood stays on the lane). The maximum score is still 300, but it's far more challenging — no perfect game has ever been officially recorded in professional candlepin play.

Each of the 10 rounds allows up to 3 balls. Strike (10 pins on 1st ball): frame ends, score = 10 + next two balls. Spare (10 pins on first 2 balls combined): pins reset, 3rd ball is thrown, score = 10 + 3rd ball. Open frame (fewer than 10 pins after 3 balls): score = total pins knocked down. The 10th round allows bonus balls: up to 2 extra after a strike, 1 extra after a spare.

In candlepin, a spare means the first two balls together knocked down all 10 pins. Since the frame allows 3 balls total, you still get your third ball — but the pins are reset for that third delivery. The spare bonus (10 + the third ball's pinfall) rewards you for knocking everything down in two and then adding more with a fresh rack. This is unique to candlepin and makes strategy around the third ball crucial.

The 10th round is special: if you throw a strike on your first ball, the pins reset and you get 2 bonus balls (3 total in the round). If you get a spare on the first two balls, pins reset and you get 1 bonus ball (3 total). If it's an open frame after 3 balls, the game ends. All pinfall in the 10th round counts toward the final score, including bonus deliveries.

The maximum score is 300, achieved by throwing 10 strikes in the first 9 rounds, plus 3 strikes in the 10th round. However, a perfect 300 has never been officially bowled in professional candlepin competition. The highest recorded score in a sanctioned match is 245 (bowled by Ralph Semb in 2011). This illustrates just how challenging candlepin bowling truly is compared to ten-pin.

In candlepin, deadwood (knocked-down pins) remains on the lane and can be used strategically. Bowlers can ricochet the ball off deadwood to reach standing pins that are otherwise difficult to hit. This adds a layer of tactical depth absent in ten-pin bowling. Skilled players learn to read deadwood placement and adjust their shots accordingly, making each delivery a unique puzzle.

Yes! This calculator follows official candlepin scoring rules as used in the International Candlepin Bowling Association (ICBA) and most New England leagues. It handles all edge cases: strike bonuses across frames, spare + third-ball scoring, 10th-round bonus balls, and partial-score display when bonuses are pending. It's perfect for practice sessions, casual play, or double-checking manual scoresheets.
