Everyone likes to be smarter. Here are some websites with free brain exercises to help get your mind in gear and keep it razor sharp.

Brain Metrix I haven’t played all the games on this website, but the ones I did play were a little addictive. The games on this website work best with a mouse, rather than a laptop touch pad.

Increase Brain Power This link will take you to directly to the brain exercises page, but there are helpful tips throughout. The website seems to be simply advice and techniques you can use in your everyday life, rather than games like the first one. They do have some links to sell merchandise, but they are unobtrusive and the site as a whole is free.

Live Strong Again, more tips and tricks rather than any actual games.
