What's the difference between per-hole and match-total bets?

Per-hole bets (like Skins, CTP, Longest Drive, Bingo Bango Bongo) settle one hole at a time. Each hole pays out independently.

Match-total bets (like a Match Play bet, Nassau, or Stableford pool) settle once the whole match or round is done. Nassau is a hybrid - three independent matches (front 9, back 9, overall 18) that each pay out at the end.

Mixing both is fine and common.
