How to Play Hammer in Golf

Updated February 2026 · 5 min read

Hammer is a doubling game that adds psychological warfare to every hole. At any point during a hole, a player (or team) can "hammer" — doubling the value of the hole. The other side must either accept the doubled points or concede the hole at the current point value. It's a game of pure psychological warfare that turns every hole into a high-pressure decision. Your opponent just hit their approach to 5 feet? Hammer them and see if they fold.

How Hammer Works

Every hole starts at a base value (typically 1 or 2 points). At any point during the hole — after a tee shot, after an approach, on the green — a player can "hammer." Here's the sequence:

1. Call the hammer: Say "hammer" (or bang the putter on the ground, whatever your group does).
2. Opponent decides: They must either accept (points double) or decline (concede the hole at the current point value).
3. Play continues: If accepted, the hole is now worth double. And here's the twist — only the team that was hammered can hammer back.
4. Re-hammering: The team that accepted can re-hammer later in the hole, doubling the intensity again. This can go back and forth.

The Doubling Sequence

A 1 pt hole can quickly become a 16 pts hole with four hammers. That's why groups often set a hammer cap (maximum number of hammers per hole) to keep things from getting out of hand.

Key Rules

Only the hammered team can hammer back. This is the critical rule. If Team A hammers Team B, only Team B can hammer next. Team A can't hammer again until they've been hammered. This prevents the side with the advantage from hammering repeatedly.

You can hammer at any time. Off the tee, after an approach shot, on the green, even after your opponent's ball is in motion (depending on your group's etiquette rules). Some groups restrict hammering to between shots only.

Declining a hammer is not shameful. If you're in deep trouble and the opponent hammers, conceding the hole at the current point value is the smart play. Don't let ego turn a small loss into a huge one.

Common Hammer Formats

Individual Hammer (1v1)

Two players going head to head. Each player can hammer the other. Simpler and more direct.

Team Hammer (2v2)

Two teams of two. Either player on a team can call the hammer. This adds a layer — one partner might want to hammer while the other doesn't. Good teams communicate.

Hammer + Nassau

Play a Nassau (front/back/overall) with hammer rules. Each of the three competitions can be hammered independently. This is the advanced version — complex but thrilling.

Capped Hammer

Set a maximum number of hammers per hole (usually 3 or 4) or a maximum hole value. This keeps the game fun without the risk of one hole spiraling out of control.

When to Hammer

When you have a clear advantage. Your ball is in the fairway, their ball is in the trees. Hammer immediately. Make them decide whether to play on for double points from a bad position.

When your opponent just hit a bad shot. Timing is everything. Hammer right after they chunk a chip or fly the green. They're emotionally low and more likely to fold.

On the tee of a hole you're confident on. If it's a par 3 you always hit the green, hammer before anyone hits. It's a power move that sets the tone.

When NOT to Hammer

When both sides are in trouble. If everyone hit bad drives, hammering doesn't give you an edge — it just raises the intensity on a coin flip.

When you're already up big in the match. Protect your lead. Let the trailing team take risks.

When your opponent handles pressure well. Some players thrive under hammer pressure. Against them, save your hammers for moments where you have a genuine tactical advantage, not just a psychological one.
