As a former game systems architect, I’ve reverse-engineered the psychological design behind 'free spins'—those so-called 'gifts' from online casinos. This isn’t luck. It’s behavioral engineering. In this deep dive, I expose how high RTPs, reward loops, and fake control create addiction disguised as entertainment. If you’ve ever felt stuck after a ‘just one more spin,’ this is why. Transparency isn’t optional—it’s ethical.
