Curling
Scoring

The winner is the team having the highest number of accumulated points at the completion of ten ends. Points are scored at the conclusion of each of these ends as follows: when each team has thrown its eight stones, the team with the stone closest to the button wins that end; the winning team is then awarded one point for each of its own stones lying closer to the button than the opponent's closest stone.

Only stones that are in the house are considered in the scoring. A stone is in the house if it lies within the 12-foot (3.7 m) zone or any portion of its edge lies over the edge of the ring. Since the bottom of the stone is rounded, a stone just barely in the house will not have any actual contact with the ring, which will pass under the rounded edge of the stone, but it still counts. This type of stone is known as a biter.

It may not be obvious to the eye which of the two rocks is closer to the button (centre) or if a rock is actually biting or not. There are specialized devices to make these determinations, but these cannot be brought out until after an end is completed. Therefore, a team may make strategic decisions during an end based on assumptions of rock position that turn out to be incorrect.

The score is marked on a scoreboard, of which there are two types; the baseball type and the club scoreboard.

The baseball-style scoreboard was created for televised games for audiences not familiar with the club scoreboard. The ends are marked by columns 1 through to the regulation number of ends for the competition (usually with an extra column to account for the possibility of an extra end to break ties) plus an additional column for the total. Below this are two rows, one for each team, containing the team's score for that end and their total score in the right-hand column.

The club scoreboard is traditional and used in most curling clubs. Scoring on this board only requires the use of (up to) 11 digit cards, whereas with baseball-type scoring an unknown number of multiples of the digits (especially low digits like 1 and especially 0) may be needed. The numbered centre row represents various possible scores, and the numbers placed in the team rows represent the end in which that team achieved that cumulative score. If the red team scores three points in the first end (called a three-ender), then a 1 (indicating the first end) is placed beside the number 3 in the red row. If they score two more in the second end, then a 2 will be placed beside the 5 in the red row, indicating that the red team has five points in total (3 + 2). This scoreboard works because only one team can get points in an end. However, some confusion may arise if neither team scores points in an end, this is called a blank end. The blank end numbers are usually listed in the farthest column on the right in the row of the team that has the hammer (last rock advantage), or on a special spot for blank ends.

The following example illustrates the difference between the two types. The example illustrates the men's final at the 2006 Winter Olympics.

Eight points – all the rocks thrown by one team counting – is the highest score possible in an end, and is known as an " eight-ender " or "snowman". Scoring an eight-ender is very difficult; in curling, it is the equivalent of pitching a perfect game in baseball. Probably the best-known snowman came at the 2006 Players' Championships. Future (2007) World Champion Kelly Scott scored eight points in one of her games against 1998 World bronze medalist Cathy King.
