You've got the general idea; now let's talk gameplay... how do you play miniature golf on a PC? The basics are simple. You have your little ball, which you click on and then hold down the mousewhile you simply move the mouse away from the ball in the opposite direction that you want to shoot. You can adjust the power of your swing by moving the cursor closer or farther from the ball. Simple.
Now the ball is rolling and, as you probably know, the aim of the game is to put the ball in the hole in as few strokes as possible. The thing that makes the Bunghole in One style of mini golf a little different from reality is the kind of holes you play. They're quite odd and in some cases very tricky, there is one where you play inside a convenience store, one in a cemetery, another in a prison quarry, a military training ground and so on.
