Coolmathgames.com is a good site for kids with free time, but there are a few problems that are not evident to the site's users that I want to go over. I used to play games on this site a while ago, but never with the intention of learning math. Probably 10% of the many games available are math related, and the rest are skill and strategy games. So don't judge the site by it's name. This site offers well over 100 games, but they seem to be lacking in quality. I'm not a game critic by any standard, but many of these ones are just filler content for the site; they don't offer anything new and exiting, and they are too simple. These are the kind of games that you get addicted to but then end up wondering why the hell you spent so much time on them. Not every game is like this, though. There are a few well thought out games that can grab a kids attention. But most are dull and simplistic, which is why I gave this site 3 stars.
