The router that I'm using has blocked some sites? (Read desc please)?

[Bob]

So I'm using a college router at school for internet and stuff, and certain websites, like facebook, and some flash games have been blocked from the router. I don't care about facebook because I've already found a way to get around that, but the games, those I really need to get to because the other people that play with me are wondering where I've gone. I need a way to get into a flash game that has been blocked by the router. Thanks for your help, and 10 points goes to the person that gives me a good answer that works! <3<3<3
