Too complex.

You turned a really good marketing tactic into an over complicated mess.
No, I don't need an extra card in my wallet.
No, I don't need an extra app on my phone.
No, I don't want to send you all my information and have you using everyone's cards to collect data about where people eat and how much they buy.
This used to be a very simple and fun game and it probably gained millions of new customers and re-engaged old ones.
Now I don't even care if it says roll up. It's not fun, there's no physical satisfaction, now it's just an extra step that helps Tim Hortons mine its customers for data.
I guess I could go to McDonalds, considering they now own/use your original coffee recipe and at least Monopoly has Peel and Reveal.
Boo Tim Hortons, I used to be a die hard..

I normally buy McDonalds coffee everyday, but have switched to Tim Hortons in hopes of winning roll up the rim. It upsets my stomach, costs more than McDonalds and I have only won two donuts in two weeks of buying a coffee per day and I don't eat donuts.
