Wheelchair curling
Wheelchair curling is governed by the World Curling Federation. Wheelchair curlers play on teams of four people.  One person on the team throws a 19.96 kilogram granite stone across an ice track.  The track is 45 meter long. At the end of the track is a big circle.  It has 4 rings.  The diameter is 183 centimeters.  There is a dot in the center.  A team tries to get their stones the closest to the center.  After each team throws ten stones, the team with the most stones closest to the center wins.
