Does it make you smarter? Probably not. Sharper? Absolutely... but don't invest your time into bullshit like Luminocity. Play games like Portal 1 and 2, games that require you to problem solve and think out side the box. I've noticed that playing those games definitely helps me to solve problems and get good at noticing the issues quicker. I am in no way smarter because of it, but ill take "sharper" over nothing any day.
