This mobile game is manipulating the entire world like a puppet master by using these psychological tactics. In 2021, Candy Plush earned 1.2 billion dollars of Revenue which is up 15x in the past decade. These puzzles use an unknown but scarily addicting strategy called Xenos Paradox No matter how often you move halfway toward a goal, you will never reach it. We hate leaving goals incomplete and Candy Crush will continue pushing out new levels and objectives to keep us addicted.

Couple this with the intermittent hits of dopamine that are rewarded through randomized map designs, and there's no need to travel to Vegas when you personally have a mobile slot machine disguised as a candy matching game.
