I think even 1000$ wagered/ticket is not enough. This promo runs 4 months, what good is it to draw from appox. 5 million tickets. I have around 150 tickets by now and already know I have 0 chance to win anything. This promo is running way too long in my eyes.
C'mon, mate, your chances are good! Your winning anything is 150 times more probable than that of someone with just one ticket, and even that person's chances are not zero.
Think of it, and don't be so pessimistic. Good Luck!

Lowering the wagered amount for the ticket does sound good for the small players but that would only mean more tickets to the high rollers. With a $1k wager per ticket you can probably lose around $10 on average.
From my experience it is indeed possible to lose around $10 for a $1k wager, but you can do it only with dice, or similar, regarding the house edge, games. Don't get me wrong, I enjoy playing slots, but I wouldn't recommend to use them for boosting your wager.
