man i cant take this anymore!!!!

my visual basic teacher is so slow and so boring but she lets us play games on the computers at school if we finish our projects. seeing as i already know most of the things she teaches, i thought this would be kewl, seeing as a i know like 4 game sites with like 10 games each! but when i type them in, i get this access denied crap cuz the school blocks these ip's! if anyone has got sites that i can play games on plz TELL ME
