Hammer is a match-play golf betting game where any player can double the bet at any point during a hole — even after a shot is in the air.
Dropping a Hammer is called “throwing the Hammer,” and once the other side accepts, play continues for double the stakes. Decline, and you forfeit the original bet on that hole.
Below are the full rules, how Hammer differs from a Nassau press, and the variations that turn a $1 hole into a sweaty $32 wager before you reach the green.
PAIR THIS WITH:
Hammer plays well alongside these match-play formats:
- Nassau — Drop a press when you’re two down. The civilized version of Hammer.
- Match Play — The base format Hammer runs on. Every hole, a separate fight.
- Skins — Every hole pays. Tied holes carry the pot forward.
Game Setup
Hammer is one of the more volatile betting golf games. Be sure to lock in the following conditions before teeing off.
- Players: Two or four. Hammer runs as a 1v1 or 2v2 match play format. With four players, decide whether the team score on a hole is best ball (lower of the two) or aggregate (both scores combined).
- Format: Match play only. Hammer doesn’t work in stroke play — the doubling mechanic only makes sense when each hole is a self-contained match.
- Base bet per hole: $1 is plenty. The bet can double, then double, then double again on the same hole. A $1 hole reaching $16 before the green is not unusual.
- Gross or net: If handicaps are in play, settle stroke allocation before the first tee. Our free golf handicap calculator handles every format, including the match-play stroke index you’ll need for Hammer.
- Halved holes: Decide whether a tied hole carries the pot to the next hole (Skins-style) or just washes. Carrying is more dramatic. Washing keeps things more friendly.
- Accept rule: Decide: are Hammers automatic, or can the opponent decline? If declines are allowed, the declining side forfeits the bet at the previous level.
STRATEGY TIP
Set a hard ceiling before the first tee. A “max bet per hole” cap — $20, $50, whatever — keeps the game in friendly territory. Without one, a single Hammer war turns a casual round into a cash transfer.
How to Play Hammer
Each hole runs as a standard match-play hole. Lower score on the hole wins the bet for that hole. The Hammer mechanic layers on top.
- Any player or team can throw the Hammer at any point during the hole. Off the tee, in the fairway, from the bunker, on the green — even after the opponent has hit their shot. As long as your ball isn’t in the cup.
- The opponent accepts or declines. Accept: the bet doubles and play continues. Decline: opponent loses the hole at the existing bet amount, and the hole is over.
- The right to throw transfers. Once a side has thrown and the opponent has accepted, that opponent now holds the Hammer. They can throw it back later in the hole — re-doubling the bet — or hold it and wait.
- No limit on Hammers per hole. A hole can be hammered, re-hammered, and then hammered again. Every accepted throw doubles the running bet.
- Every new hole resets. The bet returns to the base. Either side can throw first again.
The idea is to throw the Hammer when leverage is yours. Opponent pull-hooks one into the trees? Hammer. They short-side themselves against a tucked pin? Hammer. They leave a comebacker that screams three-putt? Hammer.
You throw when leverage is yours. You accept when you can still win. You decline when the only smart play left is to cut your losses.
Hammer Variations
Air Hammer. A Hammer can only be thrown while the opponent’s ball is still in the air. No waiting to see where the shot finishes. This makes Hammer a read on the swing, not the result — and removes the cheap “wait and see” play.
Birdie doubles. Any birdie automatically doubles the running bet, no Hammer required. This is the variation from the Justin Thomas–Jordan Spieth match on Netflix’s Full Swing. Puts pressure on every approach.
Points-only. Play for points per hole instead of dollars, then settle the round at a fixed rate at the end. Caps the damage without killing the drama.
TGL Hammer. The TGL pro tour uses its own team Hammer rules — each team gets three throws per match and the hole value goes up by a fixed point amount rather than doubling. Worth a watch on TV. Not the version you play with your buddies.
WORTH KNOWING
Hammer often gets called an “auto-press,” but they’re different animals. A Nassau press only kicks in when a side is down by 2 in a segment — a defensive tool for the trailing side. A Hammer can be thrown by either side, at any moment, on any hole. Press is a recovery mechanism. Hammer is a weapon. Check out our post for the full breakdown.
Frequently Asked Questions
Not well. Hammer is built on head-to-head 1v1 or 2v2 match play. Three players makes the the alternating right-to-throw awkward. Threesomes are better off running one of our dedicated threesome formats.
Depends on the group. Most groups play automatic acceptance — once it’s thrown, the bet doubles and play continues. Some groups allow declines, in which case the declining side forfeits the bet at its previous level. Decline rules must be agreed before the first tee.
A press is a side bet declared on a new sub-segment in Nassau when a side is typically down by 2 holes. A Hammer is a doubling bet that can be thrown at any point during a single hole — including mid-shot — and applies only to that hole. Hammer is faster, more volatile, and less defensive than a press.
More than you’d think. Starting at $1, six accepted Hammers on the same hole puts the bet at $64. That’s why most groups cap the per-hole bet — and why the Air Hammer variation exists to keep the throws disciplined.
Final Thoughts
Hammer is the most volatile betting game you can run in a foursome. It doesn’t reward consistency. It rewards reading the lie, reading the opponent, and timing the throw. One well-placed Hammer covers a bogey hole. One bad read of an “easy” shot wipes out the front nine.
Bring it to the first tee. Cap the bet. You’ll keep it steadily in the rotation.
