Darts Scorer

Darts scorer: a 501 scoreboard for up to four players. Type each visit, and it checks for busts, suggests the checkout and keeps your three-dart average, first nine, 180s and legs.

Match settings

Double out. Type the total for each visit of three darts. Impossible totals (179, 178, 176, 175, 173, 172, 169, 166, 163) are rejected, and anything that leaves 1 or goes below zero is a bust. The match is saved in this browser only.

This darts scorer does the chalking for you. Type the total for each visit, press Enter, and it takes it off the score, flags a bust, shows the checkout route when you’re on a finish and keeps everyone’s average going. It’s free, works on a phone propped by the board, and saves the match in your browser so a refresh doesn’t wipe it.

Using the darts scorer

  1. Set the game (301, 501 or 701), first to how many legs, and up to four players. Press Start new match.
  2. After each visit, type what the three darts scored. The quick buttons cover the usual ones: 26, 41, 45, 60, 81, 85, 100, 140 and 180.
  3. When a score matches what’s left, it asks how many darts the checkout took, so your average is right.

Made a mistake? Undo takes back the last visit, as many times as you need. The player who throws first changes every leg, the way a proper match runs.

The rules it checks

  • Double out. You have to finish on a double or the bull. Leave yourself on 1, or go below zero, and it’s a bust: the score goes back to what it was before the visit.
  • Impossible scores. 179, 178, 176, 175, 173, 172, 169, 166 and 163 can’t be hit with three darts, so the scorer won’t take them. It’s the classic chalker’s mistake.
  • Bogey numbers. 169, 168, 166, 165, 163, 162 and 159 can’t be checked out in three darts. If you “finish” on one, it’s treated as a bust.

Averages and stats

The three-dart average is points scored ÷ darts thrown × 3. Bust visits count as three darts for nothing, which is why a bad leg drags it down so hard. Your first-nine average only counts the first three visits of each leg, when everyone’s still scoring and nobody is aiming at doubles. It’s the better number for comparing players.

For a feel of the numbers: a pub player averages somewhere around 40 to 50, a strong county player 70 to 80, and the best professionals 95 to 105 on TV. A nine-dart leg of 501 is an average of 167.

Under each player’s score you’ll see the route the pros would take for what’s left. For the full chart, and every alternative route, see the darts checkout calculator.

Frequently asked questions

How do you work out a darts average?

Divide the total points scored by the number of darts thrown, then multiply by three. 501 in 18 darts is an average of 83.5.

What scores are impossible in darts?

With three darts you can't score 179, 178, 176, 175, 173, 172, 169, 166 or 163.

What is a bust in darts?

When a visit takes you below zero, leaves you on 1, or reaches zero without finishing on a double. The visit doesn't count and your score goes back.

Does the scorer save my game?

Yes, in this browser only. Close the tab and the match is still there when you come back.
