Brännboll is a game that is played outside. It is a little bit like baseball and usually two teams of at least three players are needed.
Each team takes turns throwing the ball to members of their own team, then the team members need to run and try to get back to the starting post before the ball gets caught by a member from the other team. If they make it back in time, they score a point.
If the ball is caught by a player from the other team, the thrower is out. The team with the most points after a set amount of rounds wins.
