Not in the UK lottery; all the tickets get dispensed from clear containers and have to be the next one on the roll (which comes out at the back so you can't see what the next one will be). They've tried educating their customers* about not buying tickets that aren't on the roll.
This to me seemed to be the core of the problem; not that the cards were crackable, but that it was possible for a user to select what card to purchase rather than just what game to play. Remove that and the problem largely goes away through simple education about valid play procedures as I suggested.
Exactly. Force players to buy the next ticket on the roll (without seeing it) and don't allow unused tickets to be returned. Problem solved.
I grew up in Maine and tickets are dispensed this way. Not sure about returning tickets, but knowing Mainers, I'd be surprised if they would take them back. It doesn't pass the straight-face test.
Problem not solved. A savvy attendant just checks the tickets on the end of each roll. If it's a winner, go ahead and buy it. Otherwise, wait until a customer buys the loser first.

(* I say educated, but there's the infamous 'Winter temperatures' scratchcard which rather undermines that concept - http://menmedia.co.uk/manchestereveningnews/news/s/1022757_c...)
