The ultimate game of tennis, involving up to four courts as the play area, no internal boundaries and the fence between courts acts as the net. Playing exemplifies such man skills and a test of such feats to continuous Mannis play. A variant may be played with four players over great distances. The manliest sporting alternative to tennis.
