Sin bin

The penalty box (sometimes called the sin bin,bad box, or simply bin or box) is the area in ice hockey, roller derby, rugby league, rugby union and some other sports where a player sits to serve the time of a given penalty, for an offence not severe enough to merit outright expulsion from the contest. Teams are generally not allowed to replace players who have been sent to the penalty box.

Ice hockey has popularized the term "penalty box." In most cases it is a small isolated bench surrounded by walls on all four sides, with the side facing the ice having the access door. There are typically two penalty boxes: one for each team. In ice hockey a period in the box occurs for all penalties unless circumstances call for an ejection or a penalty shot. If three or more players are serving penalties at once, the team will continue playing with three on the ice but will not be allowed to use the players in the box until their penalties expire.

Most leagues specify that a team cannot replace on the ice a member serving a minor (2-minute) penalty. This results in situations such as the power play, in which the opposing team outnumbers the penalized (shorthanded) team, and (in the event of coincidental minor penalties) situations in which both teams must skate with one less player on the ice.

If a team scores a goal while one or more of the opposing team is serving a non-coincidental minor penalty, the penalty with the least time remaining is cancelled, and the player serving that penalty may return to the ice. In the case of a double-minor (4-minute) penalty, the penalty is treated as two consecutive 2-minute penalties. If the opposing team scores, only the penalty currently being served is cancelled; if at least one penalty interval remains, the penalty clock is reset to reflect this (two minutes if one interval remains, four minutes if two intervals remain) and the player must remain in the box; if less than two minutes remain, the remaining penalty is cancelled and the player is released. A major (5-minute) or misconduct (10-minute) penalty must be served in full, regardless of the number of goals scored by the opposition. To keep play fair, coincidental minor penalties ("matching minor" penalties assessed to both teams simultaneously) are also served in full regardless of scoring. Goaltenders never go to the penalty box even though they are assessed penalty minutes (but they can be ejected and replaced with a substitute). Any penalties enforced against goaltenders or the bench are served by a teammate, with many leagues requiring that teammate to have been on the ice when the penalty occurred.
