How do you win at Tim's "Roll up the Rim"?

Question

I'm on a three year losing streak.

Answer 1

I've had 2 doughnuts and a coffee in 3 years, but I don't go there often.

Answer 2

You're not supposed to.

Answer 3

live in a town with small population, better odds than say if you were in a city with million+

Answer 4

you just gotta keep buying their stuff.

someone who lived in my small neighbourhood won one of the SUVs a few years back. My friend keeps winning donuts and coffees.

It's all about luck!
