How to Keep Score in Darts: Paper vs App | Oche

Keeping score is the one skill every darts player needs before they can play a real game. The good news: the method is simple. The catch: doing the maths by hand, turn after turn, is where casual games fall apart. Here’s how scoring actually works, how to do it on paper, and why most players eventually switch to an app.

How darts scoring works

Standard darts is played as 501. Both players start on 501 and subtract the total of each three-dart turn from their running score. The first to reach exactly zero — finishing on a double — wins the leg. Our scoring rules cover every detail, and the 501 rules guide walks through a full leg.

So the core loop is just:

1. Add up the three darts you threw.
2. Subtract that total from your current score.
3. Write down the new remaining number.
4. Repeat until someone checks out on a double.

If you score 60 from 501, you’re on 441. Score 100 next, you’re on 341. The running number is always what’s left to finish. Our scoring explained article breaks down the arithmetic with worked examples.

Scoring on paper or a whiteboard

The traditional setup is a chalkboard or whiteboard split into two columns, one per player. Each row shows the visit score and the new total. It works, and it’s how pubs have done it for a century — but it has real drawbacks:

• Mental maths under pressure. Subtracting 134 from 287 mid-game is where mistakes creep in.
• One error ruins the leg. Miss a subtraction and both players lose track.
• No record. Once you wipe the board, the game is gone — no averages, no checkout percentage, no history.
• Someone has to chalk. A dedicated scorer can’t fully focus on their own throw.

For a casual game between friends, that’s all fine. For practice or anything competitive, it slows you down.

Scoring with an app

A scoring app turns the whole process into tapping the numbers you hit. It does the subtraction instantly, tracks both players, and never makes an arithmetic error. More importantly, it remembers every leg — so you build up a real picture of your game over time.

The Oche X01 scorer handles all of this: it counts down from 501 automatically, suggests the best checkout route the moment you’re on a finish, and logs your three-dart average and checkout percentage to the stats dashboard. No chalk, no maths, no arguments about whose turn it is. If you want to compare the options first, see our roundup of the best free darts scorer apps.

Which should you use?

If you only ever play the occasional friendly leg, paper is perfectly fine — it’s free and it’s on the wall. But the moment you start caring about getting better, an app pays for itself immediately: it removes the mental load so you can focus on the throw, and it measures the progress you can’t see by eye.
