After the chart-topping app sensation Flappy Bird was removed from iOS and Android app stores, devices pre-installed with the game have appeared for sale online.
Dong Nguyen, the Vietnamese developer of the popular game, pulled Flappy Bird from app stores on Sunday without any clear indication as to why.
"I am sorry 'Flappy Bird' users, 22 hours from now, I will take 'Flappy Bird' down," Nguyen tweeted on Saturday. "I cannot take this anymore."
Now opportunistic gamers have sought to profit from the sudden disappearance of the game by selling devices pre-installed with the game on sites like eBay.
Smartphones with Flappy Bird installed have been appearing with prices in the thousands on the online auction site.
Many items have been attracting a lot of attention, bringing with it the possibility of also attracting fraudulent bids.
An iPhone 4S with Flappy Bird being sold by eBay user michaelyeates1 has so far attracted over 170 bids, reaching over £150,000 with five hours of the auction still to go.
The free-to-download game had been earning Nguyen up to $50,000 (£30,000) per day, according to the creator.
Those who have already downloaded the app are still able to play it, meaning that the money earned from adverts is still going into Nguyen's pockets.
However, since the game was taken down from official stores it has been appearing on torrent sites like The Pirate Bay.
For those still looking to play the game, obtaining a pirated version may not only be cheaper but – for once – morally justifiable.
