Carpet Golf 3D incorporates those obstacles you find at any miniature golf course; windmill, water hazard, bridges, and hills. Adjust the angle of the arrow to putt in any direction. The larger the arrow is, the more power your putt will have. Click and hold Swing until the aim meter reaches the desired position. If you want a straight putt, hold until the meter reaches midway. The ball is small in comparison to the hole but don't let that fool you. You will get the hang of it once you practice on one of the practice courses.
