If you're anything like us, you have the memory of a broken sieve. Names, dates, places go in one eye, ear, or other receptor, and disappear forever out of the other. Put simply, you are the human equivalent of a goldfish, although 3 seconds is pushing it. Fear not, for we have a way to train your brain to remember minute details. Its name is pain.

Simple as it may seem, the game Simon has inspired our Shocking Memory game. The circular device flashes a combination and you must mimic it in return. The combinations getting progressively more complex and your memory consequently improves. And why does it improve? Why do you not just give up and say, 'hey, my memory sucks'? Well that's because if you get the combination wrong, you get a short sharp shock of the electric kind through your hand.

Before you can say, 'I am memory man', you'll be reciting song lyrics you heard for the first time minutes before, remembering important figures in meetings, recalling the new guy's name at work with no prompting and generally behaving like an all-round good egg. All this gain for such a small amount of pain? It's got to be worth it...
