In fact, I don't have the right answer. However, usually, online lotteries do not have an active period to claim. As far as I know, the lottery we win will automatically go into our gambling account. I mean, our balance increases according to what we win. However, what I said could be inaccurate. please understand, because I am not a Lottery fan. So, to prevent unwanted things, always try to read the ToS provided by the casino.

For physical lottery tickets, as far as I know, they are not much different from online lottery casino platforms. However, there are differences. when we win the physical lottery, automatically we have to claim our winnings. Usually within a certain time, if we don't claim the lottery win, we won't have any problems. however, for a duration that is not too long. for example, only a week later we can claim it. because however, the database is usually still stored safely. However, in a case like the one you put forward in this thread, it seems that it will not be as simple as we think. even though in reality, we are claiming the rewards we deserve. However, the point is, we don't know exactly what regulations apply to physical casinos. it could be, if there is a time limit for claiming our victory. moreover, over a fairly long period of time. Apart from that, the winner must first provide prior notification of the reasons and causes if the prize will be claimed within a certain time. I hope that what I convey is not different from the actual version of the situation and regulations.
