Gadget site Firebox has responded quickly to the postal crisis, setting up a network of couriers to deliver parcels.

However, they've also been busy developing a game showing the problems they face, and the highly addictive Royal Fail game has been going down a storm online.

It asks players to throw mail over the picket lines and into courier vans, and thanks to facebook and twitter has been hugely popular within hours of its launch.
