Flappy Bird, a pixelated, side-scrolling, retro-style arcade game, features a tiny, round, odd-looking bird named Faby that wants to fly into gaps between green pipes placed at different heights in an area on the other side of a forest and cityscape beneath a bright, semi-cloudy, blue sky. The player helps Faby stay in the air and navigate the gaps. They earn a single point for each successful pass through a gap.
Yet, this first game in the series isn't simple. If the player makes Faby fly too high above a gap, the bird collides with a pipe and the game ends. If the player allows it to fly too low, the same happens. If the player pauses too long between wing flaps, Faby drops likes like a rock, hits the ground and the game ends. They must maintain a rhythm with careful observation and a perfect pace with each flap.
The game becomes more complex over time, which means that the player eventually faces a variety of deadly obstacles, including pipes that move up and down or from diagonal positions and dangerous, hungry monster plants that erupt from inside of them.
Flappy Bird is so incredibly difficult in terms of gameplay that the player receives achievement rewards for reaching low-point scores (bronze medal for 10 points, silver medal for 20 points, gold medal for 30 points and platinum medial for 40 points).
