Flappy Bird
Flappy Bird was a phenomenon. It demonstrated that simple gameplay, combined with a healthy dose of difficulty, can be incredibly addictive. While the original game might be gone from official app stores, its spirit lives on in countless clones and homages. Re-experiencing Flappy Bird, even for a few minutes, is a reminder of the brief but intense period when the world was united in its struggle against a pixelated bird and a series of green pipes.
