Oh - And what's this all about?
Potential winner(s) from Canada may be required to correctly answer a mathematical skills-testing question without any assistance in order to be eligible to receive a prize.
This is because most provinces have a regulatory office for lottery (like the Régie des Alcools des Courses et des Jeux, and Loto-Québec, in Québec), and they own the monopoly on everything that's "random" (in lotteries, contests, etc). So, if you get picked and you answer the math question correctly, you win because of the question, not because your name was picked at random.
