How do I increase my IQ?


I want to recommend my app for you guys, it is called: Brain Training Chess, It is a chess working memory game designed to increase IQ etc. It is out in the appstore now and costs only 2,99 dollars. I have many years of experience in brain training and I really think this app is one of the best brain training applications out there. If you have any feedback or questions about the app just ask away.
Best regards,

Thank you for an interesting article.
Just one question:
Why did you not put "PLAY CHESS" in the list??

"PLAY CHESS" isn't in the list because the list is about improving mental function.

I would like to read John_Warren's answer.
In my opinion, playing chess can increase one's intelligence. (Also chessplaying is an exercise for the brain.)
