Your school may have a list of approved sites; ask a teacher.
If there were a list of game sites that aren't blocked but would be if the school knew about them, all it would take would be for one administrator to find it to ensure that everything on it immediately got onto the list of blocked game sites.
Believe me, if I knew of one, I would list it here (for the administrators rather than for children who should be doing homework rather than playing games).
Not sure what you mean by "unblocked"; there are many websites where you can play for free - some of them hosting a single game, others a variety of small games.
There are loads of free games, a few are like actionmadness.com and breakontheweb.com - enjoy mate

Wait until you are unblocked by an admininstrator.
You shouldn't be going on to sites your school doesn't want you to go on, with the use of their computers. Looking for unblocked sites that your school hasn't blocked yet is a clear signal you didn't read your schools Internet Usage Agreement.
You don't need to unblock any just uninstall and install again.
