What is a Mulligan in Golf? | The Unofficial Do-Over Rule

A mulligan in golf is an informal, penalty-free do-over shot, replayed from the original spot as if the first shot never happened. It is not permitted under the official Rules of Golf and exists only through group agreement in casual play or as a fundraising tool in charity events.

That definition is the easy part. The real conversation starts with what happens after you take one. If you post that round for your official handicap, the USGA’s Rules of Handicapping require you to replace the score on the mulligan hole with your net par. The other seventeen holes count, but the do-over gets scrubbed from your record.

This guide walks through the unwritten rules, the one official consequence, and the three origin stories fighting for the title. You’ll know exactly when to ask for a mulligan, when to keep quiet, and what it actually costs you.

Key Takeaways

• A mulligan is strictly unofficial and never allowed in tournament play or any round governed by the Rules of Golf.
• If you take a mulligan in a casual round and post the score, the USGA mandates scoring net par on that hole for handicap purposes.
• Charity tournaments often sell mulligans for $20-$50 per pair as a direct fundraising tool.
• The term is common in the United States but rarely used in the UK, highlighting a key regional difference in golf culture.
• Always establish mulligan rules with your group on the first tee to avoid confusion, common limits include one per nine holes or only off the tee.

The Simple Definition of a Mulligan

A mulligan lets you pretend a bad shot never happened. You re-tee or re-drop from the exact same spot, swing again, and play on without adding a penalty stroke to your score. The first attempt vanishes from the card.

A mulligan is a social agreement, not a rule. The United States Golf Association (USGA) and The R&A do not recognize it anywhere in the official Rules of Golf. Its use is confined to recreational play where the primary goal is enjoyment, not strict competition.

This is why you’ll never see a professional like Scottie Scheffler or Rory McIlroy ask for one on television. In their world, every shot counts exactly as played. For the rest of us, a mulligan is a pressure valve. It turns a round-ruining opening drive into a chance to start fresh, keeping the game moving and the mood light. The key is that everyone in your group agrees to the same terms before anyone tees off.

Where Mulligans Are (And Aren’t) Allowed

The line between acceptable and forbidden use is absolute. Getting it wrong can invalidate a score or get you disqualified.

The Casual Round: By Group Agreement Only

This is the mulligan’s natural habitat. In a friendly weekend game, you operate by house rules. The most critical step is stating those rules clearly on the first tee. Don’t assume.

Common agreements include: * The “Breakfast Ball”: One mulligan allowed on the very first tee shot of the day. This is the most widespread and accepted version. * One per nine: A single do-over allowed anywhere on the front nine and another on the back nine. * Tee shots only: Mulligans can only be used to replay drives, not shots from the fairway or rough. * A set limit: Some groups allow three, or even eighteen, mulligans per round but restrict where they can be taken.

The table below breaks down where most groups draw the line on shot type, a major source of disagreement if not discussed upfront.

Shot Location	Commonly Allowed for a Mulligan?	Typical Group Stance
Tee Box	Yes	The default. Most groups allow it here.
Fairway	Sometimes	Less common; requires explicit agreement.
Rough or Hazard	Rarely	Usually forbidden; play it as it lies.
Putting Green	Almost Never	Effectively banned. Putting do-overs break the game’s spirit.

The Charity Tournament: A Fundraising Tool

Here, the mulligan shifts from a casual courtesy to a formal commodity. Organizers frequently sell them, often for $20 to $50 per pair, with proceeds going directly to the cause. You buy a ticket or a token at registration. This transforms a bad shot into a charitable donation, a clever way to raise money while lowering frustration. If you’re playing in a charity event, the rules are set by the organizers, not your group. Use them exactly as instructed.

The Forbidden Zones: Competition and Handicap Posting

This is the non-negotiable part. Mulligans are banned in any setting that follows the Rules of Golf. * Tournaments & Competitions: From your club championship to the U.S. Open, mulligans are grounds for disqualification. The rules offer a formal alternative for a possibly lost ball: the provisional ball under Rule 18.3. * Handicap Rounds: This is the subtle rule most golfers miss. If you take a mulligan during a round you intend to post for your handicap, that round is not played by the rules. The USGA’s fix is specific: you must post net par for the hole where the mulligan was taken. Your other seventeen holes stand, but the do-over isn’t rewarded in your scoring record.

Where this goes sideways: Assuming a mulligan is harmless in a casual match for money. If you didn’t agree to it on the first tee, taking one is cheating. It will end the friendly wager and likely the friendship.

How a Mulligan Differs from a Provisional Ball

This confusion costs strokes. A mulligan and a provisional ball solve different problems.

A mulligan is for a shot you didn’t like. A provisional ball is for a ball that might be lost or out of bounds. When you hit a drive toward thick rough or a property line, you announce you’re playing a “provisional ball” and hit again. If you find your original ball in play, you pick up the provisional and play the original, adding only the penalty for the first stroke. If the original is lost, you play the provisional under a stroke-and-distance penalty.

Mulligans have no penalty. Provisionals have a penalty if used. Mixing them up is a two-stroke mistake.

The Murky Origins of the Term

No one knows for sure. The USGA Museum backs the story of David Bernard Mulligan, a Canadian golfer and hotelier in the 1920s. After a poor opening drive at the Country Club of Montreal, he simply re-teed, calling it a “correction shot.” His playing partners named the practice after him.

A competing theory credits John “Buddy” Mulligan, a locker room attendant at Essex Fells Country Club in New Jersey in the 1930s. He argued he deserved an extra shot because his partners had time to warm up while he worked.

A third, older theory traces it to “Swat Mulligan,” a fictional baseball slugger from 1910s newspapers, where “take a Mulligan” meant taking a mighty swing.

The truth is probably lost. What remains is the term, perfectly capturing the game’s blend of frustration and second chances.

Frequently Asked Questions

Can you use a mulligan in a tournament?

No. Never. Using a mulligan in any tournament governed by the official Rules of Golf is a violation that leads to disqualification. Tournament play requires you to play the ball as it lies or take defined penalties.

How many mulligans do you get?

There is no standard number because they are not a real rule. It is 100% determined by what your group agrees to before the round. Common agreements are one total, one per nine holes, or only on the first tee.

What is a “Breakfast Ball”?

Breakfast Ball” is a mulligan limited exclusively to the very first tee shot of the round. It’s the most common and widely accepted form of do-over, acknowledging cold muscles and morning nerves.

Does a mulligan affect your handicap?

Yes. If you post a score from a round where you took a mulligan, you cannot post the actual score from that hole. According to the USGA Rules of Handicapping, you must post a score of net par for that hole instead. This preserves the validity of the other 17 holes.

What’s the opposite of a mulligan?

Some groups play a game called a “Gilligan” or “Recall,” where your opponents can force you to replay a good shot. It’s a tactical, often humorous, twist on the do-over concept. Neither has any place in the official rules.

Before You Go

A mulligan is golf’s great social contract. It’s a shared acknowledgment that the game is hard and the point is often fun, not just a number on a card. Its value lies in the agreement itself, the quick conversation on the first tee that sets the tone for the next four hours.

Remember the boundaries. In any competitive or official context, from a weekend Nassau to a club event, leave the mulligan in the bag. Use the provisional ball rule instead. But on a casual morning with friends, when that first drive dives into the trees, knowing you have one in your pocket can turn a grimace into a laugh. That’s the whole point.
