This isn't a copy of the official rulebook. It's the guide you need when you're on the 14th hole, your ball just landed somewhere strange, your playing partner is telling you one thing, you think another, and the group behind is waiting.
You won't find 200 pages of technical language here. You'll find the rules that actually matter, organized around the real situations you'll face in any round: when you can move the ball, when you lose a stroke, what to do when the unexpected happens.
And if your doubt is right now, on the course, gloves on and little patience — you have something better than a guide: the Lazar Camera. One photo, three seconds, a clear answer with the applicable rule and your best tactical option.

The rules of golf are the set of regulations that govern how each hole is played, how strokes are counted, and what happens when something goes off script. They are written by two global bodies — the R&A and the USGA — and updated every four years to adapt to the modern game.
The difference between knowing them and not knowing them is measured in strokes. An average player loses between 4 and 6 strokes per round by misapplying a rule: dropping in the wrong place, moving the ball without marking it, repairing things that can't be repaired. Multiply that across all the rounds in a year and you understand why most handicaps never improve.
The official rulebook: R&A, USGA and governing bodies
The R&A (Royal & Ancient, headquartered in St Andrews) governs golf worldwide except the United States and Mexico. The USGA does the same in North America. The two organizations have published the rules jointly since 2019, so the rules are identical anywhere in the world.
Lazar uses this official rulebook as its sole source for all answers. No free interpretation, no "what my club member says" version.

10 basic golf rules every player should know
If you're only going to memorize ten things from the rulebook, make it these. They cover 90% of the situations you'll encounter in any round, casual or competitive.
- 1
Maximum 14 clubs in the bag. More than that: two stroke penalty per hole where discovered (maximum four per round).
- 2
Identify your ball before teeing off. Mark it with a personal symbol. If you can't identify it during the round, it's considered lost.
- 3
You only have 3 minutes to search. From the moment you arrive at the area where you think it landed. After that, lost ball and stroke penalty.
- 4
Play the ball as it lies. Don't move it, don't improve your lie, don't trample the grass to flatten it. There are exceptions, but this is the default rule.
- 5
Play the course as you find it. Don't alter the terrain around your ball to make the shot easier.
- 6
Don't ask advice from anyone. Only your caddie or your team partner. Asking an opponent what club they used is a two-stroke penalty.
- 7
Respect the order of play. The player furthest from the hole hits first.
- 8
Mark your ball before lifting it on the green. Always behind the ball, never to the side.
- 9
Take care of your scorecard. Signing with fewer strokes than taken on any hole is an immediate disqualification.
- 10
When in doubt, ask. Better to stop for 30 seconds and apply the rule correctly than to assume and cost yourself two strokes. That's what Lazar is for.
Course situations that apply a specific rule
Forget rule numbers: your ball just landed somewhere odd and you need to know what you can do right now.
If your ball lands in a penalty area
Your ball enters an area marked with red or yellow stakes. You have three options: play the ball as it lies (no penalty if you can reach it), relief with a one-stroke penalty dropping on a line from the hole, or replay from the previous point (stroke and distance). If the area is red (lateral), you have a fourth option: drop within two club lengths of where it crossed.
→ Full guide: ball in penalty areaWhen your ball ends up outside the course
If your ball ends up out of bounds (white stakes), the rule is strict: stroke and distance. You lose a stroke AND return to the point from which you played. Practical tip: if you're not sure your ball will stay in bounds, always play a provisional from the same spot.
→ Full guide: out of bounds penaltyWhen the ball is in an impossible position
You have the right to declare it unplayable and accept a one-stroke penalty. Once declared unplayable, you choose: replay from the previous point, drop on a line from the hole as far back as you want, or drop within two club lengths from where your ball lies. All three carry the same penalty: one stroke.
→ Full guide: unplayable ballWhen there are abnormal course conditions
If your ball lands in an animal hole, ground under repair (GUR), or temporary water, you are entitled to free relief with no penalty. The procedure: find the nearest point of complete relief and drop within one club length of that point, not nearer the hole. Many players think they have to play the ball from the animal hole. They don't.
→ Full guide: animal holes and abnormal conditionsWhen your ball lands in the sand
The bunker has specific restrictions: you cannot touch the sand with your club before making your stroke. You can remove stones, leaves, and loose twigs (since 2019). You can rest your club outside the bunker. If your ball is unplayable inside the bunker, you can exit with a two-stroke penalty.

The green is where the most strokes are gained and where the most are lost through ignorance. The rules here are special because they differ from the rest of the course.
- →You can mark and lift your ball at any time, to clean it or because it interferes with another player.
- →You can repair any damage caused by a hand or a club.
- →You cannot repair mower damage or natural imperfections.
- →Since 2019, the flagstick can remain in while putting. No penalty if you strike it.
What damage can you repair and what you cannot
| Yes, you can repair | No, you cannot repair |
|---|---|
| Ball marks (yours and others') | Mower damage |
| Spike marks | Natural imperfections of the green |
| Animal marks | Damage not caused by person or club |
| Flagstick or hole liner marks | Footprints on your line (except your own) |
| Any damage caused by hand or club | Raised edges of hole (except yours when putting) |
Playing formats and their specific rules
Not all competitions are played the same way. The format changes how strokes are counted, which penalties apply, and even the order of play on the green.
Match play: the complete guide
In match play you compete hole by hole against an opponent. Whoever makes fewer strokes on each hole wins that hole. Penalties work differently: asking an opponent for advice is loss of hole (not two strokes). You can also "concede" a putt to your opponent, giving them the stroke without them playing it. This doesn't exist in stroke play.
Stableford: rules and scoring
Stableford is the format most commonly played in amateur club competitions. Instead of counting strokes, you count points: double bogey = 0 pts, bogey = 1 pt, par = 2 pts, birdie = 3 pts, eagle = 4 pts. The advantage: if you have a disastrous hole, you simply score 0 points on that hole. The disaster doesn't carry through to the rest of the card.
Stroke play: the official format
Stroke play is the classic format: add up all strokes in the round and the lowest total wins. It's the format of The Open Championship and virtually all professional tournaments. Because of the format's rigidity, this is where knowing the rules in detail matters most.
Golf penalty table
The most frequent penalties in amateur play, organized by the situation that triggers them.
| Situation | Penalty |
|---|---|
| Ball out of bounds (OB) | 1 stroke + distance |
| Lost ball | 1 stroke + distance |
| Ball in penalty area (relief) | 1 stroke |
| Unplayable ball | 1 stroke |
| More than 14 clubs in bag | 2 strokes/hole (max 4) |
| Asking advice from opponent (stroke play) | 2 strokes |
| Asking advice from opponent (match play) | Loss of hole |
| Touching bunker sand before stroke | 2 strokes |
| Replacing ball in wrong spot on green | 2 strokes |
| Ball strikes another ball on green (stroke play) | 2 strokes |
| Marking ball incorrectly before lifting | 1 stroke |
| Playing a wrong ball | 2 strokes (or loss of hole) |
| Signing scorecard with fewer strokes | Disqualification |
| Deliberately improving lie or line of putt | 2 strokes or DQ |
Golf rules for beginners: where to start
If you're new to the game, the last thing you need is to memorize a 200-page rulebook. These are the five minimum rules for your first competition:
- 1
Count every stroke. Even air shots. If you intended to hit the ball, it counts.
- 2
If you can't find your ball within 3 minutes, return to the previous spot and play another with a stroke penalty.
- 3
On the green, mark your ball before lifting it. Always with a marker placed behind the ball.
- 4
If anything is unclear, ask the referee or the committee. Better to stop for 2 minutes than risk a disqualification.
- 5
Sign your scorecard before handing it in. Without the player's and marker's signatures, it doesn't count.
Basic golf etiquette
Golf etiquette is the set of unwritten but universally accepted customs. They're not in the official rulebook, but violating them marks you as a novice player.
- →Complete silence when another player is about to swing. Phone on silent.
- →Always repair your pitch marks on the green. And fix one more while you're at it.
- →Smooth the sand in the bunker with the rake when you leave.
- →Keep pace of play. If your group is slow and the next group is pushing, invite them through.
- →Don't stand on the green signing scorecards. Leave the green first, sign outside.
Handicap and rules: how they affect your game
The handicap is the system that equalizes players of different ability levels. Since 2020 the World Handicap System (WHS) has been in effect, unified worldwide. Your handicap is automatically calculated using the best 8 rounds of your last 20, adjusted for the difficulty of each course (slope and course rating).
In practice, your handicap gives you additional strokes on the most difficult holes in stableford, or is subtracted from your total at the end in net stroke play.
