would typing in random codes on the dsi shop just to get dsi points be considered illegal?

Good question. I guess so. It's stealing, right? In a sense?

Good luck getting the right code

Well I think at first they might not because they might think you just messed up the code when you were putting it in. However if you keep doing it you might get caught.

What he said.

I tried it before lol. I collected the ones I bought and found a numerical sequence going on in the cards. I tried it but it didn't work.

Getting the right code would be a pain in the arse anyways.

It won't work. The code will only work if it's from a purchased dsi points card. It says so on the card and I was bored one day and got a code right, but the shop said something about the card not being activated or something.

I don't know what the policy on that would be. I can't say it would be considered stealing because you can't steal anything else in the world by guessing it. Like everyone else said, though, good luck getting a correct code, because it'll take a long, long time!

Well, I don't know whether randomly keying in codes would technically be illegal, but IF you got the codes right and managed to get some DSi points which you kept, then I would call that stealing and therefore not legal. But I reckon you'd be extremely lucky to hit on the right codes.
Whichever way you look at it - it's dishonest and you'd (hopefully) feel real uncomfortable about it - so I wouldn't try it

It would be stealing. It probably won't work, because I imagine the codes are only activated when they're paid for at the register, like most prepaid cards with codes. Good luck getting one of the few 12 digit numbers out there that has been purchased but not yet redeemed.

Ok, I think Token_Girl got it. I think it has to be redeemed too.... "Good luck getting one of the few 12 digit numbers out there that has been purchased but not yet redeemed." .....The odds are like...... 1 in 999,000,000,000,000.
