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:
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.
