Points are scored at when an end has finished.
The team with the stone closest to the centre of the house wins the end.
The team scores one point for every stone that is closer to the centre than the other team's closest stone.

Only stones that are in the house count for scoring.
If it is difficult to see which stone is closest to the centre of the house there are special measuring devices to help.

Sometimes neither team scores any points, this is called a blank end.
