Join the list any time before June 25th at 10 a.m. PT. On that date, the list will be closed and randomized, and you will receive an email with your results shortly after.
It's a one-per-household, vetted for bots and scalpers raffle, yup. Well, more of a first-wave-shuffling and then waitlist, really.
Each global region has separate quantities and lists, and each version of the box has their raffled/shuffled lists.
What's nice about that is, not only are they going to actively try to limit to one household, but as long as you get in before the 25th, even if you get shuffled to the very end, you're still going to be before anybody that comes in almost 4 days later, and have a chance to be literally first. Chaotic, but I think that's kinda fun.
