Match Fixing

In organized sports, match fixing, race fixing or sports fixing occurs as a match is played to a completely or partially pre-determined result, violating the rules of the game and often the law. Where the sporting competition in question is a race then the incident is referred to as race fixing. Games that are deliberately lost are sometimes called thrown games. When a team intentionally loses a game, or does not score as high as it can, to obtain a perceived future competitive advantage (for instance, earning a high draft pick) rather than gamblers being involved, the team is often said to have tanked the game instead of having thrown it. In pool hustling, tanking is known as dumping. In sports where a handicap system exists and is capable of being abused, tanking is known as sandbagging.

Thrown games, when motivated by gambling, require contacts (and normally money transfers) between gamblers, players, team officials, and/or referees. These contacts and transfer can sometimes be found, and lead to prosecution, by law or by the sports league(s). In contrast, tanking is internal to the team and very hard to prove. Often, substitutions made by the coach designed to deliberately increase the team's chances of losing (frequently by having one or more key players sit out, often using minimal or phantom injuries as a public excuse for doing this), rather than ordering the players actually on the field to intentionally underperform, were cited as the main factor in cases where tanking has been alleged.

Match-fixing generally refers to fixing the final result of the game. Another form of match-fixing, known as spot-fixing, involves fixing small events within a match which can be gambled upon, but which have negligible bearing on the final result of the game.
