1.) Buy a large batch of game cards (For example, those prepaid phone cards)
2.) Scratch them all off and write down the numbers
3.) Sell them all online so you're not losing any money, lol
4.) Somehow use the numbers to crack the algorithm
5.) Generate your own cards

Would this be possible at all? Wasn't there some thing where you could buy a few thousand lottery tickets and be able to crack the algorithm to get the winning lottery ticket or something? Maybe I just saw it on some fake TV show, but is that feasible at all?

Just wondering, thanks.

Also, if you have any reading material on stuff like this, or can suggest levels of math that would be required for this, that would be great. Any idea if there are any cases of someone doing this successfully?

I know it's possible because people make keygens and stuff, so couldn't you make a "cardgen" of sorts?
