I guess the rich get richer and the poor stuff the money bag's pockets.
Keep hearing this kind of argument lately :whales are making money off smaller players in promotions that are tied to wager.
That's just not how it works. I promise.
Well, it will be nice of you to give the counter argument.. because most of these promotions are designed for people to dump more and more money into it. Take the Yggdrasil promotion for instance.. you get points for each accomplishment of the tasks that are set out by them.
This week had 4 objectives on 4 Slots and it was all designed for you to improve on your previous score. Let's say my points were 350 points.... If I reach 250 points on the first Slot, it is impossible to complete the tasks on the 3 other Slots, but the challenge does not give you the option to "exit" and to restart again, you have to complete the 350 points (your previous best) before you can try again.
So you can see that it was designed to get you to wager a lot of money and they know the people chasing this has a lot of money. So the sardines cannot compete with the whales, because it needs a immortal amount of luck very early in the promotion for them to win anything.
Also, affiliates streamers does this with the casinos money and they are not excluded from these competitions.
In any way, casinos does this to make a profit, so you cannot blame them... but it should be designed to give the sardines a bigger chance to win something too.
