Vietnamese developer Dong Nguyen's version of Flappy Bird was short-lived after he removed his engaging game 12 days after becoming the most popular app in the Google Play store.

Since then, game makers have rushed to make Flappy Bird clones based on the original version, resulting in hundreds of versions becoming available.

A company called Zedge, which analyzes data from the Google Play store, found that since February 24, at least 864 Flappy Bird clones have been made available, according to online publication Digital Trends.

The imitations continued to increase in number when Nguyen pulled out the game from App Stores. Since Nguyen's announcement on February 8, 729 of the 864 clones have been launched. At its peak there were 70 Flappy Bird clones being released each day day, the publication said.

Zedge said that 24 percent of the 864 clone versions discovered had perfect ratings. Some clones have high ratings, while other are rated quite low.
