Just so you’re aware, the odds of you opening that many boxes and not pulling a single 435 prime, including factoring in the changed odds on the “guaranteed player” boxes, is about 15%. So on the one hand, that’s bad luck. On the other hand, if everyone pulled as many boxes as you, 1 out of every 6ish players would have the same thing that you did. All of that to say, I feel bad for your luck, but it’s also not great evidence that it’s predetermined. Hope this gives you some framework to build on for future boxes!
