Most casinos around the world using the same tactic to lure gamblers. First they give the money, and then they take it all.
Does that mean that you believe all casinos are rigged?
I'd say it's our greed that makes us lose it all. You play low stakes and feel like you're winning but not making enough so you play high stakes and realize you don't have enough to stay in the game.
It's not the casinos that made the game they're just a part of it.
