Free online darts scorer for 501, 301 and practice
Free online darts scorer for 501 and 301, with checkout suggestions, player statistics, practice drills and a bot opponent. No account. Works offline.
Open the appA darts scorer that stays out of your way
Open 9Darts in the browser, pick 301 or 501, and throw. Scoring is one tap a dart on a number grid, a tap on the board itself where the dart landed, or the visit’s total typed on a numpad — whichever is quickest for the person holding the phone. The app keeps the score, works out whose throw it is, calls a bust by the rules, and takes a dart back when a finger slips. Nothing to install and no account to make: add it to your home screen and it opens like any other app.
More than a 501 score counter
The same scorer plays 301 and 501 straight-in or double-in, best of any number of legs with or without sets, a bull-off to decide who throws first, and Around the World. Two people can share one phone, two phones can share one game, and one person can play alone — against the bot, or against their own numbers.

Checkout suggestions when you need them
From 170 down, the app shows the ways out: the best three-dart route for the score you are on, and the alternatives a player would actually pick, ranked the way a chalker would call them. It is the same code that generates the checkout table on this site, so a route it suggests is a route you can look up afterwards.
Every checkout from 170 down →
Train with purpose
Four drills with a score to beat — round the board on doubles, round the board on trebles, Bob’s 27, and twenty checkouts worth knowing — and Around the World as a game in its own right. Every drill is scored and kept in your history, and a coach reads your statistics and names the one worth throwing next.

Play against a dart bot
Nobody about? The bot fills the second seat of a 301 or 501 match at five levels pitched at three-dart averages of 40, 55, 70, 85 and 100 — a pub player up to a professional — so you measure yourself against a number you already think in. Its games count in your statistics like any other.
The bot, and how it is calibrated →
Play darts with friends
Two people, one phone: both names on the setup screen and the app alternates the turns. Two people, two phones: open a room, send the link or show the code, and each phone scores its own darts into one shared game — the online duel. If the connection drops, the game carries on as a local two-player game on either phone, with nothing lost.
Your statistics belong to you
Three-dart average, first nine, checkout percentage, best leg, which doubles land for you and which do not, the trend over your last games and your record against the people you play — computed on your phone from the darts you have thrown, kept there, and exportable as one file whenever you like. No account, no server copy, and nothing held back.
What leaves your phone and what does not →
Free, without interrupting your leg
Free to play, with ads — the statistics, the history and the drills included. Nothing to buy. Ads appear between games — on the first screen, the summary and the statistics — and never on the game screen while darts are being thrown.
Ready? Open the app and throw the first dart. There is nothing to install and nobody to sign up with.
Common questions
Is 9Darts really free?
Yes. Every game, every mode, the bot at all five levels, the online duel, the statistics, the history and the drills. The ads between games pay for it, and there is nothing to buy.
Do I need an account?
No. There is nothing to sign up for and nothing to log in to. Your games are saved on your phone, and Settings can export them as a file and import them on another.
Does it work offline?
Every solo game does — 301, 501, Around the World, the drills and the bot — with the radio off. The online duel is the one thing that needs a connection, because two phones have to agree.
Can two people score on two phones?
Yes. One phone opens a room and the other joins by link or code; each scores its own darts into one shared game. If the connection drops, either phone carries on as a local two-player game.
Does it suggest checkouts?
From 170 down it shows the best route for the score you are on and the alternatives a player would actually pick — the same routes as the checkout table on this site.
How good is the bot?
It plays at five levels pitched at three-dart averages of 40, 55, 70, 85 and 100. Each level is calibrated by simulation over tens of thousands of legs, so the number on the bot is the number it actually averages.
Which games does it score?
301 and 501, straight-in or double-in, best of any number of legs with or without sets; Around the World; and four practice drills — round the board on doubles, round the board on trebles, Bob’s 27, and twenty checkouts worth knowing.
Can I install it like an app?
Yes. It is a web app: open it once in the browser and add it to your home screen, and it opens full-screen like any other app and keeps working offline.
