Ironically, I noticed this about two years ago but concluded it wasn't actually a big deal. They are pretty clear that it's a game of chance - not a game of skill. And analogous to actual scratch cards.
It's almost analogous to actual scratch cards: while on actual scratch cards the printed numbers are given, online the order in which the ('printed') numbers appear is given.
Yes. In any case, it's not a big deal. If it was any other way, we all would have hacked it by now.
