Drag your mouse around in the main window (where your golfer is 
standing). The arrow at the top represents where your ball will 
land. 

As you aim, pay attention to the circular map on the left of the
screen. This shows you a top-down view of the course. The blinking
flag represents the hole, and the smaller flag is where your ball 
will land at the end of the current stroke. Note that if you change
clubs, the smaller flag will change positions based on the range 
of each club. 

Directly below the map is a number showing you how many yards the 
ball is from the hole. Use this number to help determine which club
to use. 

Below the map is a blue "C." This is the swing gauge. Note the two
red triangles, one on the top and the other on the bottom of the 
gauge. Once you're satisfied with your aim on the course, you'll 
be clicking your left mouse button three times: 

Click once to start the swing gauge indicator climbing towards the
top triangle. The top triangle represents the power of your stroke. 


Click again when the indicator is lined up with the triangle -- 
this represents optimal power. Click to the left of the triangle
for less power, and to the right for more. This click will now 
send the swing gauge indicator back down towards the bottom 
triangle. The bottom triangle represents the angle at which the
face of your club hits the ball. 

Click once more when the indicator is lined up with the bottom 
triangle to hit the ball square on. Click early (to the left of
the triangle) and your ball will curve left (hook). Click late 
and your ball will curve right (slice).
