The Ba' Game is a version of medieval football played in Scotland, primarily in Orkney and the Scottish Borders, around Christmas and New Year.
The two sides are called the Uppies or the Downies, depending on which part of town they were born, or otherwise owe allegiance to.
The ball must be man handled, and play often takes the form of a moving scrum.
Unlike traditional mob football, people are generally not hurt from play.
