Most schools have internet proxies that don't allow students to visit popular online flash game sites, like MiniClips, etc. So if you're a student, and you're looking for an easy way to get around those firewalls, here's your answer!
Basically, over the past couple months, my site's traffic has been exploding. Most of my site is filled with technical stuff, web development code, and SEO tips. However, when I looked at my web analytics and comments trends, I realized that the vast majority of visitors are simply searching for some popular online games. My helicopter game alone gets the highest amount of traffic out of all the hundreds of pages on my site.
So, if you're a student, and you want to play online games at school, you can just bookmark my site, and visit the online games category! If you have any requests for new games, just ask for them in a comment, and I'll get them up! Oh, but please don't use my comment box for chatting or inappropriate language, I'll delete the comments and ban you.
Oh, and one more cool thing. If a teacher comes, you can quickly switch to one of my programming tutorials to make it seem like you're actually learning something ;).
