Now look here. Give that grey matter of yours a technically challenging workout with the assistance of this fiendish looking contraption. It's got string. It's got loops. And it's got balls. Notwithstandings its looks, it is actually an instrument of emotional rather than physical torture, with a whole load of brain-ache thrown in for good measure.

Designed to tax even the most connected of neural pathways, this genius device has a simple motive: to lure one into setting out on a seemingly simple course, only to entrap the hapless victim in its many loops, coils and strategic challenges.

Sound enticing? Beware. For it looks easier than it sounds. Your objective, at least, is simple enough: move the loose disc from one end of the apparatus to the other. There. Now, that can't be too hard, can it?

There are too many questions to answer here. Why is that golf ball there and does it play an intrinsic but unseen role in unlocking the answer? How on earth can I get the loop over an object that's bigger and wider? Who won the FA Cup in 1948? And why do so many socks go missing in the washing machine?

Frustration abounds, as does the natural temptation to shout, complain and stomp off in a fit of pique. Just like being at work, really.
