If you come to a situation where a prize hasn't been claimed and there's few cards left to be sold, it's like counting Blackjack cards, the odds might change in your favour, or in favour of everyone who buys any ticket.<p>If that happens you need to do a bit of optimizing risk, assuming you have a limited amount of money to potentially lose. Kelly Criterion will have something to say here.<p>It really depends a lot on the details of the game. Are prizes rolled over if nobody found a winning card? Do cards expire? Is there a bulk buying discount? What is the nature of randomization? Does every region get its own guaranteed share of winners?<p>And crucially, is there information released about the progress of the game? This is maybe the toughest bit to figure out. With quant hedge funds you get this thing where you have to do a lot of asking questions about how the data was collected, to ensure your assumptions hold.<p>Tax I mentioned since it seems they formed a limited company.
