Two players at the net (half way inside the service court) on one side; one player centered at the baseline on the other side.
Net players cover the whole court (alleys included), baseline player covers only the singles court (doubles alleys are out).
The net players start the point with a courtesy feed to the baseline player. They play the point out.
Scoring: Play to 10 where only baseline player scores points. The net players try to stop the baseline player from scoring against them.

Note: This can be a very exhausting game for the single player.
Once the baseline player scores 10 points, players rotate one spot clockwise so that each one of them will compete against the two other players at the net.
