SupremeThe_BOSS wrote My school is exactly the same, what we do is get a usb, you can add games to it and play them off the usb, here are some games i have:

Slender man
Halo Evolved
Minecraft

Normally any .exe game would work fine im sure you can find some. Just keep in mined that sometimes the teacher will ask you to delete the game or unplug it(sometimes it can get the whole class in trouble and cause a school order of no usb allow during class/school rule), I usually sit with my friends at lunch when we have finished everything and just play till the bell rings. Also in some games you can Lan link with another computer and play system link matches.

Ill try that out but the ones I hate are the ones you have to install , my friends have dead island but it doesn't save, thanks

If you would like to get around your schools web protection go home and Download a program called "Ultrasurf" and put it on a USB and when at school open it up on your school computer. This allows you to get around your schools security and gain access to; youtube, facebook, and other blocked sites.

Flash Player games man that's you're best bet

Well you can try the password for admin as delladmin
