| for the scratchcards i dont think their flash. i remember playing that little scratchcard lottery game when i played neopets(like a year ago) and im pretty sure it was java or html. which are both exploitable, but i dont think you can exploit them in any way that would be profitable. if i remember correctly he outcome of the card was predetermined when you drew the card(it doesnt matter what you scratch, you will always have the same outcome). making it impossibe to profit unless you can determine which card you draw.
i could be thinking of a different game, but if not im pretty sure this is how this works |
