Four Square

It may have been a while since you dusted off the old sidewalk chalk and played Four-Square, so you may want to brush up on the general rules here:

In addition to the standard rules, any player who serves 5 consecutive times can make his/her own rules. However, to keep things fair, one can only use the following rules on his/her 6th serve:

• Double Taps: This means any player may hit the ball two times in the air after it has bounced once in his/her square. Similar to a one person volleyball team, this is an effective technique for setting yourself up for a spike.
• Body Language: This rule allows the server to require players to use certain body parts to hit the ball. To keep things fair (and PG), the server can only call rules that involve the appendages. ("No Hands," "No Arms," "Knees only," "Feet only," etc.)
• Black Jack: If a player catches the ball before it lands in his/her square, the player who hit the ball is out. It usually forces the game to be played low and fast and creates a different dynamic.
• Underhand: The means that all hits are with an open hand, palm up, below the waist. This brings the game down low to the ground and makes your quads ache the next day. "Underhand" is stereotypically associated with beginners, but in four square even the best players sometimes can't survive a round of underhand.
• Big Ball: Any rule maker can choose to switch to the big 16" blue ball.

Remember, temporary rules last only as long as the person who made them remains in the 4-Square. Knock him/her out, and the rule is gone until someone again serves five times in a row.

Scoring will be a little tricky, and with four or more people playing at the same time, a standard double-elimination tournament won't be possible. So it'll work like this:

Like in the other events, each Nation will submit two players to the Four-Square event. Players will then be divided into two groups. Each group will be comprised of one player from each Nation. Each group will play two 20-minute "heats". (Group 1 will play for 20 minutes, then Group 2 will play for 20 minutes. Then each group will play again. There will be 10 minutes between heats. Order will be randomly determined for the first heat, and then reversed for the second.) During game play, each player is responsible for counting the number of times he/she serves the ball. After all four heats are completed, all players serve totals will be tallied and ranked in each group. The top half (and ties) of each group will advance to the championship round of Four-Square. ALL SCORES ARE THEN RESET TO ZERO. The championship round will consist of one 30-minute heat. (Although scores are reset to zero, players' scores from the first two heats WILL determine serving order in the championship round.) Again, each player is responsible for counting his/her serves. Scores will again be tallied at the end of the heat, and players will be ranked accordingly. Players will accumulate championship points for themselves and their Nation according to their rank, and the player with the most serves will be declared Four-Square Olympic Champion.
