In Quebec, the program is known as Pari sportif; in Ontario and Atlantic Canada, it is known as Pro-Line while in British Columbia, it is known as Sports Action.
[1] Therefore, Pro-Line is a parlay game where bettors wager on the outcome of anywhere from two to six (BC and Atlantic) and three to six (Quebec, Ontario and Western Canada) of the matches offered by the lottery corporation.
[1] PROLINE+ is a mobile-optimized site that offers betting markets for at least 12 popular sports, including hockey, football, MMA, and tennis.
To make matters worse for the bettor, the parlay requirement compounds the overround - the actual vigorish is a minimum of 160% but can rise to well over 300% (if six selections are made).
In jurisdictions such as the United Kingdom where genuine competition is allowed, bookies often pay bonuses for winning parlay bets to help offset the compounded vig.
This occurs when a significant amount of wagering is placed within a short span of time, typically on a specific combination of outcomes.
The reasoning behind having such caps is to dissuade professional, or 'block', bettors from attempting to take advantage of potential flaws in the posted odds, and thus limits the liability for the corporation on a given combination of outcomes.
Typical block betting behaviour involves placing large sums (often thousands of $) on a very small amount of combinations, trying to focus on perceived flaws as much as possible.
Though most experts agree that the odds offered on Sport Select are such that even the sharpest punter would have no hope of making a profit in the long term, some have.
The Toronto Raptors and Vancouver Grizzlies began play in the league in 1995 only after the provincial lottery corporations agreed to stop offering wagering on all NBA games.
[3][4][5] In September 2016, it was announced that an agreement had been reached between the parties to allow betting on NBA games on Pro-Line in Ontario to resume beginning with the 2016–17 season.
