WHO had even heard of Flappy Birds a few weeks ago?

Its rise to prominence has been as dramatic as, no doubt, will be its eventual slide into obscurity.

The game, which can be played on devices such as iPhones, has been withdrawn from the market by its owner.

But for now, it is still big news – and it is big business. People love to make a quick buck, and who can blame them?

The Oxford-based makers of Clumsy Ninja recently sold up for more than £300m – so there is clearly a market for this kind of thing.

Devices with Flappy Birds on them are now going for hundreds, if not thousands of pounds. Cash in quick, if you can, or just shake your head at the latest bizarre 21st century craze.
