the world cup challenge was a great example of a challenge where both people who have a lot of money and people who don't have a lot of money would have the same chances of winning the contest, but these types of challenges are not profitable for the casino, at least they are not very profitable, I think that way because people were participating in the contest without spending money and the casino would be spending money on having to pay them when they win, contests that involve buying tickets and whales buy a lot of tickets so casinos win a lot in this type of contest, just like the lottery in the real world, the rich are the ones who have the greatest chance of winning the lottery, strange that in the past on TV they showed faces of poor people who won the lottery, today they are very rare cases in which they see someone without money win the lottery the maximum prize
I have to say that life is not always fair and it should not be "fair" it should be just, and that means the guy with that much money at risk is providing something more to a casino and they should get more because of it, you and I not having that much money is not the whales fault, and why should be try to balance the rewards towards people like us when whale did nothing wrong and deserves what they have.
