Profit - online casino with fairness control

This is a vague attempt to explain the mechanics of getting tournament tickets, without any specifics. It all feels like a black box to me. If anyone has figured this out, I'd be happy to hear it.
Speaking for myself, I played European roulette (VS) today and was awarded 21 prize chips and one lottery ticket. But the algorithm for awarding tournament chips is still a complete mystery to me. I was also hoping to get at least the first tournament ticket, since, according to the casino representative, "the first tickets are easier to earn than subsequent ones." But alas, no such luck.

I received my second lottery ticket and at the same time my first ticket to the tournament arrived!
It might just be a coincidence, I don't even know and there's no one to ask. The tech department isn't even aware of it.
