It must be pretty successful, still remember the buzz around McMonopoly in the late 90s as a kid
As per recent documentary McMillions, in 1995-2000 a fraud ring netted almost all the US prizes. $24 Million. 53 ultimately indicted in connection to the crime. Trial started on 9/10 2001 and was obviously overshadowed in the press.
I remember being a kid and badly wanting a play station, got two tokens but probably had no chance.
I kinda used to like it but now to get any of the minor prizes you basically need to use the friggin app. Companies wanting you to download their app piss me off.
The non-food instant win prizes are getting worse too, like $30 at some online store if you spend $150 on full priced stuff. Better off just waiting for a sale.
There was something more satisfying with the hands on approach.
