Explanation:
ECLIPSE BALL
Eclipse ball was designed by combining the teamwork of volleyball, the quick spontaneity of badminton, and the excitement of tennis. Â Rules were designed for fun and action.
The racquet is used as an extension of the arm. Â If played correctly, a light touch is as important to the strategy of winning as is a fiercely hit return. Â Both aggressive and non-aggressive players can work well together.
OBJECT OF THE GAME:
Game is played to 21. Â Only the serving team can score. Â You must win by 3 points.
A “skunk” games is 11-0.  Failure to return the ball to your opponent results in a point or a side out.
SET UP:
A team consists of 4 to 6 players typically.  The court is actually a volleyball court. (30’x60’).  The net height is 8’. Â
THE SERVE: Â
Rock, paper, scissors; volley, or spin the racquet to see who gets to serve. Â Your opponent then chooses which side of court they want to defend.
The serve must be UNDERHAND from Âľ court or further back. Â Be sure to call out the score when you serve. Â Remember: Â ONLY THE SERVING TEAM CAN SCORE. Â Rotate clockwise, like in volleyball.
SERVICE RETURN/ RALLIES:
Teamwork and passing the ball to a teammate is encouraged.  Try to set each other up for the “SLAM”.  You may hit the ball twice in a row; however, you cannot SCORE off a double hit.  In other words, you cannot set yourself up and spike the ball, and score. Â
During play, the ball is allowed to bounce once in bounds any number of times (bounce, hit, bounce, hit, etc.) before it is returned to the opponent.  SPECIAL RULE:  You are allowed ONE double bounce opportunity per side, per volley.  For example, you can’t quite reach a ball, it bounces once, bounces a second time, and you get to it and send it over.  THAT IS PERFECTLY LEGAL.  HOWEVER>>>>IT CANNOT HAPPEN AGAIN UNTIL THE NEXT SERVICE OR DEAD BALL OCCURS. Â
ALSO:  The ECLIPSE Ball is usually hit with the racquet.  HOWEVER…it is not against the rules for a player to use their hands, head, feet or other body parts to keep the ball in play.  It IS against the rules to catch and throw the ball.
RECOVERY OPTIONS:
If the ball lands IN BOUNDS, then, (for example) hits the bleachers, the ball is still in play. Â If trying to return a ball that is OUT OF BOUNDS, you are allowed to hit the ball three times consecutively. Â
A player may NOT enter the opposite team’s court in ANY WAY to recover the ball. LIKEWISE, you may not, AT ANY TIME, go under the net to play a ball. Â
