Basketball Rules & Formats

1. The basics: court, kit and how a game works

Basketball is the simplest sport in the world to start and one of the deepest to master. Two teams try to put a ball through a hoop mounted 3.05m (10ft) above the floor at opposite ends of the court, defending their own basket while attacking the other. There's no real equipment barrier — a ball, two hoops and ten willing players and you have a game.

The court and kit

A full FIBA court is 28m by 15m, with a three-point arc 6.75m from the basket and a free-throw line 4.6m out. In a UK club you'll almost always be on a sports-hall floor with basketball markings rather than a dedicated arena, which is fine — the lines are the same. You need an indoor composite ball (size 7 for adult men's and mixed, size 6 for women's), and two contrasting kit colours or bibs so it's obvious who's on which team. That's the lot.

How a game works

Five players a side are on the court — the standard full-court game is five-on-five. The game starts with a jump ball, and from there it's continuous: the team with the ball (the offence) tries to score; the moment they score or lose possession, the other team attacks the opposite basket. Players move the ball by dribbling (bouncing it as they move) or passing; you can't run while holding it. A made shot is worth points, play restarts, and the clock keeps running. Fouls — illegal contact — stop the clock and can award free throws. The whole thing is governed by a clock, which is the key to understanding how basketball is scored.

2. How scoring works (the timed game)

Basketball is scored two ways at once: how much each basket is worth, and how long you have to make them. Both matter for running a club session.

What each basket is worth

• Two points — a made field goal (any shot) from inside the three-point arc.
• Three points — a made field goal from behind the three-point arc.
• One point — a made free throw, the uncontested shot awarded after certain fouls.

So a final score might read 47–42. There's no "win by two" and no fixed target to reach in the standard game — you simply accumulate more points than the other team within the time available.

The clock decides it

This is why basketball uses timed scoring rather than a points race. The professional FIBA game is four ten-minute quarters; the NBA uses four twelve-minute quarters. But for a club run you don't need quarters and a stoppage clock — you set a single game length and play to it. In ClubLono, basketball defaults to a 20-minute game: tip off, play, and when the clock reaches zero whoever is ahead wins. That's the whole mechanic. It's deliberately different from a sport like badminton or pickleball where you play to a points cap — here the clock is the finish line, which is what makes rotation predictable. You know a game lasts twenty minutes, so you know roughly when the next team is up.

For a casual turn-up night you can drop the formal clock entirely and play "first to 21, win by 2" or "next basket wins after 15 minutes" to keep things moving — but the moment you're tracking results for a table, a fixed clock is fairer and removes every argument. ClubLono runs the timer and records the final score, so the host can play instead of watching a stopwatch.

3. The rules people get wrong

Pick-up basketball is full of confidently-asserted rules that are slightly wrong. Knowing the real ones keeps your sessions calm and your newcomers from being bullied off the ball.

• Travelling. You can't take more than a "gather plus two steps" while holding the ball without dribbling. Beginners shuffle their feet constantly; in a social game, call it gently or let small ones go, but know that it's a real violation, not pedantry.
• Double dribble. Once you stop dribbling and hold the ball, you can't start dribbling again. You also can't dribble with two hands. This catches out players who've only ever shot hoops in the driveway.
• The "and one". If you're fouled in the act of shooting and the basket still goes in, it counts and you get a free throw — you don't have to choose. Lots of casual players wrongly think a foul cancels the basket.
• Backcourt violation. Once your team has advanced the ball over the halfway line, you can't pass or dribble it back into your own half. Common in social games where nobody's tracking it, but it's a turnover under the real rules.
• Reaching in isn't automatically a foul. Reaching for the ball is only a foul if you make illegal contact. Clean steals are legal and good defence — don't let anyone call "foul!" just because you took the ball cleanly.
• The shot clock is optional for clubs. The pro game has a 24-second shot clock to stop stalling. Almost no club run uses one; if stalling becomes a problem, a soft "use it or lose it" house rule is plenty.

4. Running a social session

Most club basketball isn't a formal league — it's a weekly run where whoever turns up gets a good game. The format you pick decides whether that's fun or chaos.

The recommended format: pool into a playoff

When you have enough for three or four teams — a busy club night, or a one-day event — ClubLono's recommended basketball format is pool play into a playoff. Every team plays each other once in a round-robin pool, so everyone is guaranteed several games regardless of how they're playing that day. The pool results seed a knockout stage: top teams cross into semi-finals, winners into a final. It's the format that respects everyone's time (nobody loses once and goes home) while still producing a real winner. ClubLono builds the pool fixtures, tracks every result and seeds the playoff for you.

Sensible alternatives

• Winners stay on. The classic pick-up format: the winning team keeps the court, the losers rotate off and the next team comes on. Simple and self-managing, but it can let one strong team dominate the floor — pair it with a time cap per game so nobody's frozen out.
• 3x3 (three-a-side). Played half-court to a single basket, 3x3 is the perfect small-numbers format — you only need six, games are short and frantic, and it's now an Olympic discipline in its own right. If you're short of a full ten, switch to 3x3 rather than cancelling. Standard 3x3 is played to 21 points or a 10-minute clock, whichever comes first.
• Mixed and balanced teams. For a social club, reshuffle teams each week or each round rather than letting the same five stick together. Balanced, mixed-standard sides produce close games, and close games are what bring people back.

5. Running a league across a season

Once your club is big enough for several settled teams — or you're organising a local league across multiple clubs — you move from a weekly run to a proper season with a table.

Divisions and fixtures

If you have more than six or eight teams, split them into divisions by standard so games stay competitive — a runaway 60–15 every week helps no one. Within a division, the standard structure is a round-robin where every team plays every other team, usually home and away (twice each) across the season so the schedule is balanced and no team gets an easy or brutal run of fixtures. With venue-sharing common in basketball, "home and away" often just means alternating which club books and hosts the hall.

Points and standings

Basketball league tables are typically ranked on win/loss record — or a points-for-the-table system (commonly 2 for a win, 1 for a loss, 0 for a no-show forfeit, which rewards turning up). Because every game produces a score, ties in the table are broken cleanly by head-to-head result first, then points difference (points scored minus points conceded across the season), then points scored. That points-difference tiebreak is basketball's equivalent of goal difference, and it's worth stating in your league rules upfront so a tight title race doesn't end in an argument.

Promotion, playoffs and a finish

Decide before the season how it ends: straight champion (top of the table wins), or a playoff where the top four cross over into semis and a final for a proper showpiece night. Promotion and relegation between divisions keeps the lower division meaningful. Whatever you choose, publish it on day one — the worst league disputes happen when the rules for the finish get invented in the final week.

6. How ClubLono runs basketball

ClubLono is built so the organiser plays instead of refereeing a spreadsheet. For basketball specifically:

• Timed scoring, automatically. Set the game length (20 minutes by default), and ClubLono runs the clock and records the final score. No stopwatch on the side of the court, no scrawled tally that gets argued over.
• Pool-and-playoff format built in. Pick the recommended format and ClubLono generates the round-robin pool fixtures, tracks results live, and seeds the knockout playoff from the pool standings — for a club night or a one-day event.
• Standings that maintain themselves. Every recorded result updates the table instantly, with win/loss record and points difference calculated for you. No end-of-night maths.
• 5v5 and 3x3. Run full-court five-a-side or switch to 3x3 when numbers are short — the scoring and standings work the same way.

Casual weekly runs, timed games, the queue and result-tracking all work on the free tier, which is £0/month for a single club with no time limit. Full season leagues — divisions, home-and-away fixtures and maintained standings across a season — are a Premium feature. Premium is £19.99/month or £199.99/year (with a 14-day free trial on either) and drops the platform fee on any paid sessions from 5% to 1%, alongside multi-club hosting, kiosk mode, cross-club stats and DUPR export. There is no per-player fee, and ClubLono never holds members' funds — money from any paid entry goes straight to the host's bank account via Stripe.
