Dong Nguyen of Vietnam created the mobile game Flappy Bird in 2013. Its simple concepts and engrossing gameplay made it an internet sensation hit, but the game's high level of difficulty and frustration also garnered criticism.

Flappy Bird puts players in charge of a little bird and challenges them to guide it through a maze of interconnected pipes. It takes a lot of preparation and time to go through the holes without damage by the pipes or the floor. You want to get the maximum score possible, so you'll need to pass through gaps successfully.

Flappy Bird is easily recognizable by its difficult gameplay. Players frequently uncover themselves trying to keep the bird airborne while avoiding the hazards, contributing to the game's notoriously harsh gameplay. As a result, quite a few players became hooked, always challenging themselves and others to higher scores and boasting about their accomplishments on various social media platforms.

Flappy Bird, with its difficult and annoying gameplay, is often recognized as a cultural phenomenon that captivated millions of gamers worldwide. A significant and indelible addition to the books of mobile gaming, it has ignited conversations around game design, addiction, and the effects of these games on their mental health.
