Canadian statistics professor games Tim Hortons contest for 80-98% win rates
Briefly

All you had to do, if you really wanted some free coffee and doughnuts, was wake up around 3 am each day and click on some virtual Tim Hortons coffee cups.It was 3:16 am, actually, that gave a University of Waterloo professor a roughly 80 percent win rate on Tim Hortons' Roll Up To Win game.That wasn't as good as the 98 percent Michael Wallace clocked in early 2020, when he discovered a quirk in the coffee chain's prize distribution scheme, but it still made for great lessons for his students.
