Brain-training games might be good fun but they probably don't make you cleverer. In an experiment for the BBC television programme 'Bang Goes The Theory' 11,000 people used the games for six weeks and took tests of their memory, concentration skills, planning ability and problem-solving. There was no improvement in the people playing the game compared to those who simply surfed the Internet for the same amount of time. Scans taken of some of the volunteers showed that the training had no effect on the make-up of the brain either.
