Get the ball in the hole in as few strokes as you can. Each hole has its own par, set by how long and tricky it is. One round is 9 holes, and everyone plays the same course each day. The dice are up to luck.
Don't like your tee shot roll? Re-roll it once. You also get 3 mulligans per round to re-roll any time.
Keep an eye out: on some days Bigfoot is hiding on one hole. Spot him for a free mulligan.
