Varpa
Varpa is an old outdoor game. The game dates back to the Viking Age and survived in Gotland together with several other medieval or Viking games. No official nationally sponsored Varpa teams exist, however unofficial leagues are growing in popularity among youth in suburban areas.
It is similar to boules but played with a flat and heavy thrower known as "varpa" instead of balls. These used to be well-shaped stones, but nowadays aluminium is more popular. "Varpa" is an old word which simply means "to throw".
Varpa is one of the disciplines at the annual Stånga Games (Stångaspelen).
