Croquet Shots
There are several ways to shoot the ball in a croquet shot, each with their own advantage

Drive shot:  The standard shot, strike the ball with the mallet parallel to the ground with normal follow through.  The object ball moves farther than the striker ball.

Stop shot:  In this shot, the mallet strikes the striker ball with a slight upward angle with a minimum of follow through, more of a snap shot.  This 'stops' the striker ball.  This shot lets you get a lot of distance on the object ball without moving the striker ball as much as a drive shot.

Roll shot:  In this shot, the mallet strikes the striker ball with a slight downward angle with a lot of follow through.  This moves the striker ball a much longer distance.  Depending on the angle and the follow through, you can shoot a half-roll, where the striker ball moves half the distance of the object ball, or a 3/4 roll, or a full roll, where the striker ball moves the same distance as the object ball.

Pass Roll shot:  This shot is similar to roll shot, but the angle is steeper and the follow through is even more.  If done correctly, the striker ball will move farther than the object ball.  In most cases, you will slightly split the ball (shoot at an angle) so the striker ball can get past the object ball.

Take-off shot:  In this shot, the striker ball just barely wiggles the object ball and receives the full force of the mallet.
