Candy Crush. It's easier, more fun, and not as much of a pain (until you get to a terrible level,) but even then it's still easier to get to the next level than it is to get up in Flappy Bird. Plus FB is simply more annoying and boring... it's just constant dying and I suck at it.
Neither. I've been stuck on the same level of Candy Crush for 6 ****ing months, I'm so close to deleting the app and Flappy Bird just makes me scream and want to smash my phone
