Darts Rules & Formats

1. The basics: board, kit and the object of the game

If you can throw a dart at a wall, you can play darts. The depth is all in where you aim and how you finish — but the entry point is about as low as sport gets, which is exactly why a darts night fills up so easily.

The board

A standard clock board has the numbers 1 to 20 around the edge in a deliberately scattered order (so a wayward dart is punished — miss the 20 and you're likely in the 1 or the 5). Each number has a thin outer ring that doubles the score and a thin inner ring that trebles it. In the centre, the green outer bull scores 25 and the red inner bull (the bullseye) scores 50. The highest score with a single dart is the treble 20 — 60 — which is why you'll see good players grouping all three darts in that one small bed.

Kit

A set of three darts (steel-tipped for a bristle board), a sisal bristle board hung at the right height, and a marked oche to throw from. That's the lot. Darts come in brass, nickel-silver or tungsten — tungsten is denser so the barrels are slimmer and group more tightly, which is why most regulars use them — but a beginner is fine on a cheap brass set to start.

How a game works

Each player throws three darts per turn (a "visit"). Darts that miss the board, bounce out or fall out before they're collected don't score. You take it in turns, and the structure of the game decides what you're aiming for — in the standard club game, that's getting your score down from 501 to exactly zero. A match is usually played as the best of a set number of legs (e.g. best of five legs), and bigger matches group legs into sets.

2. How countdown scoring works in darts

Darts uses countdown scoring, and the canonical club game is 501. The idea is simple and the finish is where it gets interesting.

Counting down from 501

Both players start on 501. Each visit, you add up your three darts and subtract that total from your remaining score. Throw treble 20, treble 20, treble 20 and you've scored the maximum 180 in one visit, dropping from 501 to 321. The aim is to be the first to get from 501 down to exactly zero.

Double out — the finish that catches people

You can't just reach zero any old way. In the standard game you must finish on a double — a dart in the doubles ring, or the bullseye (which counts as a double 25, i.e. 50) — that takes you to exactly zero. So on 40 left, the classic finish is double 20. On 32, it's double 16. If you need 50, the bull does it.

Busting

If a visit takes you below zero, exactly to one, or to zero without finishing on a double, you've "bust" — that whole visit doesn't count and your score reverts to what it was at the start of the turn. That's why you can't be left on 1 (there's no double to finish from 1), and why good players steer their score toward "friendly" finishes rather than blindly scoring big. Leaving yourself on 32 is a far better position than leaving yourself on 41.

Straight in vs double in

Most social play is straight in — you can start scoring from your very first dart. Some leagues play double in, where nothing counts until you've hit a double to "open". Decide which before you start; it changes the whole rhythm of a leg.

3. Rules people get wrong

Darts is simple until two regulars disagree mid-leg and the whole night stops. Settle these before they come up.

• "Bust" reverts the whole visit, not just the last dart. If you're on 40, hit a single 20 (now on 20), then a treble 20 — you've gone bust on that dart, and your score goes back to 40, not 20. The good darts you threw earlier in the visit are wiped too.
• The bullseye is a double. The 50 (inner bull) counts as a valid double-out finish. The outer bull (25) does not finish — it's an odd number's worth, and it isn't a double.
• Darts must stay in to score. A dart that bounces off the wire or falls out before the scorer agrees the visit is collected doesn't count. No re-throws.
• You can't finish on 1. There's no double that leaves zero from 1, so landing on 1 is an automatic bust. Players forget this and leave themselves stranded.
• Order and which player throws first. A "bull-up" (each player throws one dart at the bull; closest throws first) decides who starts, and the player who starts the match usually alternates the throw each leg. Sort it at the top or you'll argue about it at the death of a tight leg.
• Feet behind the oche. You can lean over the line, but your feet must be behind it. Toe on the line is a foul throw in a strict game — though most social nights are relaxed about it, which is exactly why a marked oche matters.

4. Running a fair social night

On a busy one-board night, the format is the difference between everyone getting a throw and three loud regulars hogging the oche. The trick is to score players on their own results rather than bottlenecking the room on head-to-head pairings.

Stroke play — the recommended social format

The cleanest way to run a social darts night is stroke play: every player throws their own game (a leg of 501, a round of nine-dart "highest score", a Round the Clock run) and is scored on their own result, then ranked against the field. Because nobody's waiting for a specific opponent to be free, the rotation keeps moving even with one board and twenty players — you simply call the next person up when the board's free, log their result, and the standings update. It's fair, it's fast, and a beginner and a county thrower can play in the same event without the beginner being publicly whitewashed.

Sensible alternatives

• Winner stays on. The pub classic — win and you hold the board, lose and you go to the back of the queue. Social and self-policing, but it can let one hot player monopolise the oche, so cap it at two or three wins before they rotate off.
• Round the Clock. Hit 1, then 2, then 3… up to 20 and the bull, in order. A brilliant warm-up and a genuinely fair beginner game — accuracy matters more than power, so newcomers aren't outgunned.
• Cricket / Tactics. A tactical game on the 20 down to 15 plus the bull — good for mixed abilities because it rewards thinking over raw scoring.
• Handicaps. Start weaker players on a lower number (say 301 vs 501) so games stay close. The single fastest way to make a mixed-ability night feel fair.

Fair matchmaking

However you run it, keep an eye on grouping people of roughly similar standard for the competitive bits and using handicaps or stroke play for the mixed bits. A rating that updates as people play takes the guesswork out — you're not trying to remember who beat whom three weeks ago.

5. League formats for individuals

Once you've got regulars who want to keep score over a season, a structured competition gives the night a spine. Darts is largely an individual game, so these formats all work for ranking single players (and you can run a doubles version of any of them).

Ladder

Every player sits on a rung. You challenge someone a rung or two above you; win and you swap places. Best for: ongoing, low-admin competition that runs in the background of your normal nights. Players self-organise the challenges, and the ladder rewards consistency without needing a fixture list. The downside is that an inactive player can squat near the top, so add a "must defend within X weeks" rule.

Box league

Split players into small groups ("boxes") of four to six of similar standard. Everyone in a box plays everyone else over a period, the top one or two are promoted to the box above and the bottom relegated. Best for: guaranteeing everyone competitive, evenly-matched games — nobody's stuck playing only the club's best or worst. It's the format that keeps the most people engaged and is a brilliant fit for a club with a wide spread of ability.

Knockout

A straight bracket — lose and you're out. Best for: a one-night cup or a season-ending championship. Quick and dramatic, but a beginner drawn against your best player is done after one match, so seed the bracket (strong players spread across it) and consider a plate competition for first-round losers so the night isn't over for half the room by 9pm.

Round robin

Everyone plays everyone. Best for: small fields (six to eight) where you want a clear, fair winner and maximum games per player. It's the fairest format there is, but the fixtures balloon as numbers grow — twelve players is sixty-six matches — so for bigger clubs, run round-robin groups feeding into a knockout final stage.

6. How ClubLono runs darts

ClubLono is built so the host can throw instead of refereeing a chalkboard and a clipboard.

Darts runs on countdown scoring out of the box — log each visit and the app keeps the 501 count, flags a bust, and recognises a legal double-out finish so the leg ends cleanly. The default event format is stroke play, which is exactly the fair, fast, one-board-friendly structure described above: every player throws their own game, results are logged, and the standings rank the whole field automatically. A built-in rating updates per game, so groupings and ladders stay sensible without you doing mental arithmetic between legs.

The roster, the queue, the night calendar and the members-only chat are all on the free tier — a single club costs £0/month with no time limit and no feature cliff. Leagues — the ladders, box leagues, knockouts and round robins above, with automatic tables and fixtures — are a Premium feature, alongside multi-club hosting, kiosk mode for a tablet at the oche, cross-club stats and DUPR export. Premium is £19.99/month or £199.99/year with a 14-day free trial on either, and on paid nights it drops the platform fee on each payment from 5% to 1% (the host always receives the payment less Stripe's 1.5% + 20p). Money goes straight to your bank account via Stripe — ClubLono never holds members' funds, there's no per-player fee, and a cancelled paid night auto-refunds every booked player.
