Is there any sense in brain gym games?

Hello everyone,



I've been reading reviews about the website, Luminosity, where they tout clinical trials about their product (as does others such as MindSparke, from what I can vaguely recall). My question is, how much of this is true? Are there any realistic "brain gym" programs/websites out there that are closer to established research and science? Is Luminosity a genuine way of improving your mental performance (either dexterity, intelligence etc.), a scam or somewhere in-between?



Thanks in advance.
