Three matches in one round: front nine, back nine and overall.

Three chances to have a good day, and a way back into the round at the turn.
How it works
Worked example
One bet lost, two won. Front nine slipped away, the back nine came good.
| Front nine | Lost 2 & 1 |
|---|---|
| Back nine | Won 3 & 2 |
| Overall 18 | Won 1 up |
Result
Two of the three bets won
See it
Front nine holes 1–9
▼ Lost 2 & 1
Back nine holes 10–18
▲ Won 3 & 2
Overall holes 1–18
▲ Won 1 up
One bad nine costs one bet, not the round. That is why golfers have played a Nassau for a hundred years.

FAQ
Three separate match-play bets running at the same time: the front nine, the back nine, and the overall eighteen. Each is settled on its own, so you can lose one and still finish ahead.
A press is a brand new bet opened mid-round by the side that is behind. It starts on the next hole and runs to the end of that nine. The original bet keeps running untouched.
A press that opens by itself as soon as a side falls a set number of holes down — usually two. Nobody has to ask, and nobody forgets. The app opens it on the right hole and tracks it separately.
Yes, two ways. As two teams playing four-ball, where the better ball of each pair counts. Or as a round robin where everyone plays their own Nassau against everyone else — that is six matches with three segments each, which is where the app earns its keep.
Yes. Shots are given on the hardest holes by stroke index. Four-ball match play is normally played off 90% of course handicap from the lowest player; singles match play is 100%.
The app explains it to whoever needs it and keeps the score for everybody.
