To be quite honest, the scientific studies that have been carried out on brain training games haven’t been all that conclusive. Generally they seem to suggest that, at best, some people showed improvements while others didn’t notice any difference.

But whenever you ask someone who’s been pumping a few neurons with a pocket game, they invariable feel like they've made some significant headway (that’s a ‘pun’) in the cultivation of rational thought.

Video games might encourage us to sit around, physically inactive, but surely there’s no denying that a well made game encourages cerebral activity. Who hasn’t found themselves out of breath after a vigorous bout on a shooting or fighting game? Or thoroughly energised after a high speed chase in a racing game?

And whether their effects are lasting or not, brain trainers give you an undeniable cerebral work out, so we thought we’d take a look at a these 100% Brain Games to give your mind a good spring clean.
