Flappy Bird shared similarities with other games Nguyen had previously released on mobile devices, such as Shuriken Block or Super Ball Juggling. The graphics paid tribute to retro sprite art, the gameplay was delightfully straightforward, and the difficulty level was set quite high, resulting in games that lasted only a few seconds.

The concept seemed incredibly straightforward: Tap the screen to ascend, let go to descend, and navigate through openings in a sequence of green pipes that were clearly inspired by the ones in the Super Mario series. The gaps were generously spacious, significantly surpassing the bird's height. However, due to the bird's rapid movements and quick dives, successfully navigating through the gap without crashing became quite a difficult task. Considering that you only receive one point for each pipe cleared, it is highly probable that your high score will be in the single digits, if not zero.
