Skill testing question
Skill testing questions (or STQ) are a legal requirement attached to many contests in Canada. (Contesting note: There is no Canadian Federal law requiring an STQ. Federal law cites that if an entity has an STQ requirement for a contest, that it is stated up-front informing consumers. However, some provinces do have an STQ law. As level of education is not applicable under the Canadian Human Rights Code, discrimination against those who are educationally-challenged is not a consideration.)
Origin
The combined effect of Sections 197 to 206 of the Canadian Criminal Code bans for-profit gaming or betting, with exceptions made for provincial lotteries, licensed casinos, and charity events. Many stores, radio stations, and other groups still wish to hold contests to encourage more purchases or increase consumer interest. These organizations take advantage of the fact that the law does allow prizes to be given for games of skill, or mixed games of skill and chance. To make the chance-based contests legal, such games generally consist of a mathematical STQ.
The Promotional Contest Provision of the Competition Act also states that "selection of participants or distribution of prizes is not made on the basis of skill or on a random basis."
Question format
The most common form that these questions take is as an arithmetic exercise. A court decision ruled that a mathematical STQ must contain at least three operations to actually be a test of skill. For example, a sample question is "(2 × 4) + (10 × 3)" (Answer: 38). Enforcement of these rules is not very stringent, especially for small prizes. The player may not be required to answer the STQ to claim a prize. Anecdotally, getting the answer wrong is also often not an obstacle to claiming a prize. The questions are also becoming easier. For contests held in other countries but open to Canadians, a STQ must be asked of any potential Canadian winner.
Free entry alternative
The same section of law prohibits receiving consideration in exchange for playing the games, resulting in a related peculiarity of Canadian contests: the free entry alternative, which is usually indicated by "No purchase necessary" in the fine print. Generally this means that it is possible to enter the contest for free by, for example, writing a letter to the entity sponsoring the contest and requesting a game piece or entry form.
