The game, Shark Attack, asks the player to save the lives of swimmers by caging sharks that are lurking nearby and remembering where they were located. 1-10 swimmers are in a lagoon. Sharks move towards the swimmers and encircle them. Swimmers can be saved by the player placing a cage around the shark. Points are scored for the number of sharks successfully caged on the first attempt. Music accompanies actions in the game, and there is applause from beachgoers when sharks are successfully caged.
This is one of the first brain training games designed by a practicing clinical neuropsychologist, Dr Narinder Kapur, Visiting Professor of Neuropsychology at University College London. It is also one of the first games designed with principles of cognitive neuroscience in mind.
