Trebuchennis is just like tennis except each player brings one or two trebuchets which he/she uses to serve the ball. The trebuchets may be placed anywhere behind the baseline (see tennis court lines), but note that many placements are undesirable because they impede the player. The trebuchets should be easily movable since they will need to switch sides of the court with their players.

Trebuchennis was invented by Colin Chan in the early twenty-first century. No games have been played as of 9 September 2014.
