The rules
Before you tee off, put the four of you in an order. That order is the rotation, and it never changes: first golfer is the Wolf on hole 1, second on hole 2, and so on round and round. Over sixteen holes everyone gets four turns.
The Wolf tees off last. That is the whole engine of the game — he stands on the tee having seen three drives, knowing exactly what is on offer, and has to commit before anyone plays a second shot.
The three choices
Everything the Wolf can do on a tee, and what each one is worth. The point values below are the common ones; groups change them all the time.
Scoring, worked all the way through
Wolf scoring is zero-sum. Every hole nets to nothing: whatever the winning side takes, the losing side pays between them. That one property is what makes the running total trustworthy, and it is also what makes it a nuisance to do in your head.
Three holes from the same round, at a dollar a point.
Holes 17 and 18
Four golfers into eighteen holes does not divide. The rotation covers sixteen, and the two that are left over go to whoever is losing: last place is the Wolf on 17, and last place after 17 is the Wolf on 18.
Treat that as the game rather than a variant. A rotation that just runs out leaves the man who is down with two holes and nothing to play for, and the closing stretch is exactly where a Wolf game should have something at stake. Being handed the wolf twice, with a triple available on both, is a real way back — and it is why nobody in a Wolf game is ever out of it walking off the sixteenth.
House rules worth agreeing on the first tee
Wolf has been played a hundred ways. None of these is wrong. Settle them before you tee off, because every one of them changes who wins.
Scoring Wolf without doing the arithmetic
Wolf is the hardest of the common golf games to keep on paper, and it is worth being honest about why. Every hole you have to remember whose turn it was, what he chose, which side won it after strokes, and then push a different number into four different columns — three of them negative. Miss one hole and the total is wrong for the rest of the day.
Halved does that part. You post gross scores like any other round. It knows whose wolf it is, asks for the pick on the tee, applies the strokes, and keeps everyone’s number in dollars where the whole group can see it.
Play Wolf. Let something else keep score.
