The Game of Bottle Cap Soccer

Materials:

• Black plastic folding table, such as can be acquired at Wal-Mart
• Seven bottle caps: two triples of identical caps (preferably unbent); and a lone cap, which is best somewhat bent
• chalk of the highest caliber

Setup:

1. The game is played on one half of the table. Players stand facing each other on opposite sides of the table. Draw a circle in the center. Each player draws an equal sized rectangle, centered horizontally, with one long edge on the edge of the table they're standing in front of. This is each player's goal.
2.  Flip a bottle cap. The winner is offense.
3. Place the unique cap face/printed side down in the center circle. This cap is called the ball. The loser of the bottle cap toss is defending first. They arrange their three caps face/printed side up however they like on their half of the field.
4. The offense may now set up their caps however they like on their half of the field.
5. An example of a correctly set up table:
   
    

Gameplay:

1. The object of the game is to score by getting the ball to come to rest on the table inside your opponent's goal. The ball may enter from any direction. If any part of a cap touches the boundary line and/or interior of the goal, the cap counts as inside the goal. Scoring resets the game with you (i.e. the player who scored) as the defender.
2. Games are typically played to 5, win by 2. Matches are frequently decided by the best of 3 games. 
3. The offense flicks 1 of their 3 caps in order to move the ball toward their opponent's goal. The cap may touch any other caps on the table, including those of the defense. 
4. If this hasn't resulted in a score, the other player now takes a shot. Continue alternating turns in this fashion until someone scores. If any caps fall off or cross into the other half of the table, see the section "Out of Bounds."
5. If the ball ends the turn on the table inside your opponent's goal and it is not a score, then it counts as going out of bounds on your opponent's side. See the section "Out of Bounds" for more information.
6. If the ball ends the turn within one cap's width of the boundary, move it perpendicular to the boundary so that it's two caps' width away from the edge. This does not include the boundary of the goal.
7. If the ball ends up on top of a player's cap, move it to the closest position where it can lay flat on the table. Likewise if a player's cap ends the tun on top of the ball or any other cap, move it to the closest place it can lay flat.

Out of Bounds:

1. If the ball goes out of bounds on the side, return it face down to where it went out of bounds. The opponent flicks the ball directly next turn instead of flicking one of their own caps. See rule 6 about scoring when flicking the ball directly.
2. If the ball goes out of bounds on your opponent's side of the table, place it face down, centered horizontally in front of your opponent's goal. The opponent flicks the ball directly next turn instead of flicking one of their own caps. See rule 6 about scoring when flicking the ball directly.
3. If the ball goes out of bounds on your side of the table, place it face down on the corner of the table closes to where it went out of bounds. The opponent flicks the ball directly next turn instead of flicking one of their own caps. See rule 6 about scoring when flicking the ball directly.
4. If a player's cap goes off the table anywhere but behind either goal, return it face up to where it went out of bounds.
5. If a player's cap goes out of bounds behind either goal, place it face up in front of the goal aligned with where it went out of bounds.
6. If you are flicking the ball directly, you can only score if the ball touches one of your own caps before or while coming to rest. 

Special Weird Flip Rule:

Normally, if the ball is flipped face up, flip it back face down. Likewise, if a player's cap is flipped face down, flip it face up again. But, if your turn ends with the ball flipped face up and the cap you flicked face down, the ball is now your cap and the cap you flicked is now the ball.
