💡 Setup Tips
📏 Regulation Throw Distance: The official oche distance is 7 ft 9.25 in (2,370 mm) measured horizontally from the face of the board. Always measure from the board face, not the wall.
🎯 Double-Out Strategy: When finishing on a double, aim for D16 (32 remaining) as a primary target — a miss to the single 16 leaves D8, and another miss leaves D4, keeping you on a double path.
📊 Darts Per Leg Estimate: Divide the starting score by your average score per turn, then multiply by 3 (darts per turn). Add 1–3 darts for the checkout. Example: 501 ÷ 45 avg = ~11 visits = ~33 darts.
⚠️ Safety Zone: Allow at least 5 ft (152 cm) of width around the oche and 11 ft (335 cm) of depth. Wall protection behind the board is strongly recommended for dart safety and board longevity.

The feature for finishes is real help. When one tries to reach all darts finishes and it seems too difficult, simply enter the remaining score, press button and the finish shows. Even better, if one busts ore hits a hard single, enter the real darts score in the right cell, and it recounts the finish based on the spot.

Also about statistics worth to mention. A good darts scorer can count the average of the match, the leg average, the highest throw and the best finish. Based on the style of game, it gives also percentages of finishes for various areas.
Because the darts land one by one, the percentage of finishes stays precise the whole time. Some tools even follow weaknesses, so that players can improve themselves more soon.
To count the three-darts average is fairly easy. Divide 501 by the number of darts used in a leg, then multiply by three. So, if a player ends with 15 darts, the average for that leg is around 100.
The method keeps working even during finishes.
Some calculators work right in the browser, so that you do not need to download anything. They include a picture of a darts board, suggested finishes, averages, total averages and the number of thrown darts. One supports several players, together with options like Double Out, Master Out and Straight Out.
