Frustration based pay to win – Hearthstone Review

With extra code written into its rng to keep you winning and losing based on algorithms to make sure you are at the frustration level most likely to make you pay. Its not subtle. They literally make the either hand feed you a win or make sure you can not win. Just to make sure you feel bad enough to try to make the feeling go away by paying them money.
