I’ve had a mild interest in rugby for some time, and touch rugby sounded like a fun variant — “similar to rugby but without the tackling, scrumming, rucking, mauling, lineouts and kicking.”
In fact, it sounds quite a bit like (American) touch football, but with six touches instead of four downs, no forward passing or punting, and some different lingo. For instance, if you’re touched, you have to return to where you were touched and “rollball” (more-or-less “hike” the ball) to a “dummy half” (quarterback) who can’t get touched (I’d say “sacked”) or your team loses possession (not just one of its six touches). Also, the dummy half can’t score; he has to pass the ball along to another player.
Defenders have to back off five meters (yards) from the ball before the rollball — 10 meters (yards) on the first play of the game or after a touchdown — which, by the way, lives up to its name: you have to touch the ball down past the try (goal) line to score.
