Fixed matches are sporting events with the course and/or outcome of the game known in advance to the participants. They do exist and are punishable by law. All kinds of sports organizations and betting shops are fighting against them. After all, the main reason for the parties to agree on the course and outcome of a sporting event is to make money by betting on sports. Not only bookmakers, but also ordinary users, who want to get rich at the expense of guaranteed results, lose on the fixing.
