You don't need to bring a partner. Here is the Format:
1) Matches are timed at 20 minutes.
2) Spin to decide who serves. Switch sides after 4 games.
3) No-Ad Scoring. Gender to gender, if N/A the receivers choice.
4) Record the score of your match, play as many games as you can in the 20 minutes. (e.g. if Jen & Tim beat Han & Melissa 5-3, then Jen & Tim each give each other 5 points, Han & Melissa each give each other 3 points).
5) Winners stay on court, losers move one court down. Teams split up.
