Table

ComparisonHammerround robin
One lineA match-play side game where players can call a hammer to double the current hole’s agreed stake.A schedule where each player or side meets the others in separate head-to-head matches.
PlayersMinimum 2; ideal 2 head-to-head or 4 as two sides. A three-player version is a house arrangement, not covered here.Minimum 3 competitors or sides for a meaningful schedule; ideal 4-8, with each participant playing the others in turn. This is an individual field or a field of sides, not one group playing every hole together.
Scoring unitThe hole, with a dollar stake attached; the hole winner receives the agreed current stake. A halved hole and carryover treatment must be agreed before play.Each match is scored hole by hole as match play; the overall table uses agreed match points, wins, halves or another competition countback.
Handicap methodHammer has no separate WHS allowance. If the underlying game is individual match play, WHS Appendix C recommends 100% of each player’s unrounded Course Handicap when calculating Playing Handicap; the lowest Playing Handicap normally plays off zero and others receive the difference. For four-ball match play, Appendix C recommends 90%. Confirm the Committee or group’s Terms because Hammer is an informal overlay.For individual handicap match play, use the competition's stated allowance; WHS Appendix C recommends 100% of the unrounded Course Handicap for individual match play. After Playing Handicaps are calculated, the lowest plays off zero and each opponent receives the difference. A round robin involving teams or another form must not automatically inherit this allowance: the Committee should state the allowance and stroke-index method in the Terms of Competition.
Money settles howSet a base stake before teeing off, such as $1 per hole. A valid hammer doubles the current stake; agree whether it is automatic or may be declined, whether halved-hole stakes carry forward, and whether the stake resets after a won hole. Settle net amounts at the end, not by treating a casual side game as an official Rules competition.Only if stakes are agreed: settle after the round-robin table, using the announced value for each match point, win or final placing. The Rules of Golf do not set a round-robin payout or betting convention.
PaceUsually the same as match play or slower than ordinary stroke play, as each hole still uses match-play scoring but calling, accepting and recording doubles adds decisions. This is an editorial tendency, not a measured timing claim.Slower overall than one stroke-play round for the same field is the usual tendency, because a round robin requires multiple head-to-head matches and scheduling; this is an editorial planning judgement, not a measured statistic.
Best forTwo golfers who want head-to-head match play with a negotiated money side game, or four golfers already comfortable with two-sided match play and clear pre-round limits. It suits players who enjoy risk decisions and can keep the stake modest.Club leagues, social groups and small competitions that want everyone to meet several opponents rather than be eliminated after one loss.
WeaknessThe stake can escalate quickly, and unclear choices about acceptance, carryovers, timing, concessions or four-ball sides can create arguments. The group must agree a cap or stop rule if players do not want an unexpected liability.It needs more match slots than a knockout and can create tie-break disputes or uneven schedules when players withdraw, so the Committee must publish the draw, points and tie procedure.

Worked example

Illustrative inputs and selected terms, not historical results. For an accepted single hammer on an agreed $2 hole stake, the stake becomes $4. If Alex wins the hole, Ben pays Alex $4 under that expressly chosen house rule. Four entrants Alex, Ben, Chris and Dana in an all-play-all schedule need 6 pairings. That schedule is different from the rotating six-hole partner game sometimes given the same name.
