Nguyen took down the game from Apple and Google App store in February. The game is no longer available to download for either Apple or Google users but its fans can still have fun if they have already downloaded the game to their devices.

Nguyen Ha Dong, a Hanoi-based game developer, announced the grounding of the addictive game in a Tweet on Saturday. He also apologised to Flappy Bird users.

"Twenty-two hours from now, I will take 'Flappy Bird' down,” Dong said, adding that it is not related to legal issues.

"I cannot take this anymore," he wrote.

Flappy Bird caused a sensation after rising from obscurity to become one of the most downloaded mobile games on both Apple and Google’s online stores.

Users have to steer a bird between green pipes. The Android version has been downloaded up to 50 million times and attracted more than half a million reviews.

Many people have been questioning Dong on Twitter about his decision to take down the game as a day earlier he had been talking about developing the game for Microsoft’s Windows phones.
