I played Candy Crush for a while a few years ago. It's a fundamentally fun game, and the trap is that every once in a while I'd hit a level that I couldn't get past ( at least without being really, really lucky). So you I'd paid to get past it and move on to more fun. I spent maybe about $5 on it before ultimately getting tired of it. My rationalization was the game was legitimately fun and I didn't mind throwing the developers a little money for providing a decent little game. But I've seen so many similar games where the game itself wasn't fun at all, even though the rewards were still enticing. The Simpsons Tapped Out comes to mind. And in those cases I realized the game play itself wasn't interesting or fun and quickly quit. Basically, any game that has timers in it will fall into this category because the timers are there solely to make sure you keep coming back and have a compelling reason to do it often.
