Spot-fixing is an illegal activity in a sport in which a specific aspect of a game, unrelated to the final result but upon which a betting market exists, is fixed in an attempt to ensure a certain result in a proposition bet. Examples include minor events such as timing a no-ball or wide delivery in cricket or timing the first throw-in or corner kick in association football.
