Victory!
Was at McDonalds today as it was 95c cheeseburger night (remember this is New Zealand currency) and as a student, cheap = good. Anyway as I was waiting for my food, I emptied the change in my wallet into the charity water filled skill game thingee. The last coin (a 50c piece) managed to land on one of the platforms by itself rather precariously. So I am now the proud owner of a Big Mac voucher.
