Popular game Flappy Bird flies no more

HANOI ?- The developer of Flappy Bird, the former most popular free mobile game on the Apple Inc App Store and Google Inc's Android Play store, took the game down at midnight on Sunday as he announced he would do 22 hours earlier.

The game is no longer available to download for either Apple or Google users, but its fans still can have fun with the bird if they 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 at 1900 GMT on Saturday in which he also apologised to Flappy Bird players.

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

"I cannot take this anymore," he wrote.

His Tweet attracted more than 136,000 Retweets as of 0430 GMT on Monday.

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 only a day earlier he had been talking about developing the game for Microsoft's Windows phones.

Dong could not be reached for comment. He turned his telephone off after cancelling an interview with Reuters on Thursday and not finalising arrangements for one on Friday.

Unlike other successful game makers like Rovio Entertainment, which produced the hugely popular Angry Birds game and has hundreds of programmers, Dong made Flappy Bird by himself in a few nights, he said on Twitter earlier.

The game, which he said was inspired by Nintendo's Mario Bros, has been earning on average $50,000 a day from advertising, Dong said in a media interview.

Two friends of Dong said Nintendo had sent him a warning letter, but the Japanese game maker said it was not considering a lawsuit.

"It sounds very much like a rumour and if it is, we certainly can't comment on that," Nintendo's media representative said on Friday.

One gaming company manager said Dong's decision to take down the game was wise.

"Dong is taking one step back to avoid legal risk because it's too difficult to deal with legal issues himself if it happens," said Duy Doan, a senior manager at VTC Online, one of Vietnam's leading game companies.

Dong said earlier that he was not looking for any investors and would not sell the game. One expert said investors would not be interested.

"Flappy Bird is not to the taste of many game investors because it's just hit-based which will bring very uncertain cash flow and no recurring," said Nguyen Hieu Linh, investment manager at the Japanese CyberAgent Ventures Inc.

"I doubt he needs to fund raise as he's already earned a certain amount of money and he doesn't need more help to make this kind of mini game," Linh added.
