The Hammer is a battle modifier: switch it on in Best Ball or Sixes and every hole becomes a standoff.
Any time during a hole, either team can throw the hammer — but only until a player takes their grip and addresses the ball. Once someone is at address, it's too late: the hammer stays down until that shot is struck. When it flies, the hole instantly goes double-or-fold.
Throw when they're in trouble, not when you're playing well. The hammer is a pressure instrument. Its value comes from the position on the ground — opponent in the trees, you in the fairway — not from how confident you feel. Throwing after a good drive of your own is the most common way to lose double.
The address rule is the whole timing game. You can throw it right up until a player takes their grip and settles over the ball. That means the window is widest when someone is walking to their shot and thinking about it — which is precisely when they're least comfortable accepting.
Folding is a real strategy, not a surrender. Fold and you concede the hole at its pre-throw value. Losing one unit deliberately instead of gambling two is often the correct play, especially early in a match when the hole isn't decisive.
Only the accepting side can re-throw. Accept at 2×, and the hammer is yours — you can send it back at 4×. That's what turns a hole into an escalating duel, and it's why accepting when you're actually in good shape is so powerful.
Late holes with a lead: fold freely. If you're up with three to play, protecting the match is worth more than any single doubled hole.
The Hammer is the feature people tell their friends about. It takes an ordinary hole and turns it into a live negotiation — a moment where somebody has to look at somebody else and decide whether they believe in their own next shot.
It also fixes golf's dead stretches. A match that's 4 down with six to play is normally over; with the hammer in play it's one throw away from being alive again. Nothing else in this app rescues a lopsided round so completely.
And it produces the specific, delicious silence that follows the word being said out loud. Everyone stops. Everyone looks. Somebody has to answer.
The Hammer doesn't have its own stake — it multiplies whatever the host game is already worth. Every hole starts at 1× with the hammer in the air; throw and accept takes it to 2×, then 4×, then 8×.
That means the number to watch isn't the hammer, it's the underlying rate. A $5-per-hole Best Ball match is a $40 hole at 8× — and since Best Ball settles team against team, that's $20 out of each losing pocket. Set the base stake with the hammer in mind, not as an afterthought. Folding pays the winner at the pre-throw multiplier, which is what keeps the escalation honest.
Accept, and the double is live — and the hammer changes hands: only the accepting team can throw the next one. Re-hammers stack: 2×, 4×, 8×…
Fold, and you concede the hole at the old stake. Cheap insurance or slow bleed — your call.
Every hole starts fresh at 1× with the hammer in the air. Throw it when your opponent is in the trees.
