Overview
Rugby sevens is sanctioned by the IRB, and is played under substantially the same laws and on a field of the same dimensions as the 15-player game. While a normal rugby union match lasts at least 80 minutes, a normal sevens match consists of two halves of seven minutes with a one-minute half-time break. The final of a competition can be played over two halves of ten minutes each, with a half-time break of two minutes. (In the IRB Sevens World Series, only the Cup final, which determines the overall winner of an event, is played with 10-minute halves; all finals for lower-level trophies are played with 7-minute halves.) This allows rugby tournaments to be completed in a day or a weekend. However, sevens scores are generally comparable to union scores; scoring occurs much more frequently in sevens, since the defenders are more spaced out.
Many sevens tournaments have a competition for a cup, a plate, a bowl, and a shield, allowing many teams of different standards to avoid leaving empty handed.
Sevens tournaments are traditionally known for having more of a relaxed atmosphere than fifteen-a-side games, and are often known as "festivals". As The Encyclopedia of Rugby Union Football (1976) puts it, they gained their "popularity as an end of season diversion from the dourer and sterner stuff that provides the bulk of a normal season's watching."
Fans frequently attend in fancy dress, and entertainment is put on for them.
The Hong Kong Sevens tournament has been especially important in popularising the game in Asia, and rugby sevens has been important as a form of international rugby "evangelism", hence is perhaps the most widely played form of the game, with tournaments in places as far apart as Bogota and Bangkok, Kuala Lumpur and Kenya, Singapore and Scandinavia, as well as the countries in which rugby union is well known.
