To spread the celebration, Canada's most reliable coffee spot is changing the game of their "Roll Up The Rim To Win" contest.\nWhether they drink coffee or not, every year, Canadians play for their chance to win one of many prizes. Contestants roll up their rims and cross their fingers in anticipation of receiving a doughnut, a coffee, a muffin and even a car. This year, in honor of Tim Horton's 50th birthday, each cup will feature two chances at a win.\nAlongside the 47 million prizes including visa gift cards and Tim Cards, Tim Horton's will be giving away 50 2014 Toyota Corolla Sports cars for their 50 years of existence, different from the usual 40.\n“When brainstorming, someone said ‘Hey, you know what we could do? We could still use the rim ,we don’t need to have some other mechanic. Canada is so used to being able to roll up the rim. And then everything kind of snowballed and there was this collision with the obvious opportunity to add another roll and 10 more cars,” said Glenn Hollis, Tim Hortons vice-president of brand strategy.\nHave you rolled up the rim yet?
