This is a Linux issue not a Koha issue.  What you need is a kiosk environment 
and there is loads of info on the web about this.  Basically lockdown the 
desktop.  If your desktop is KDE, seek out kiosktool; if it's gnome, you need 
lockdown editor.  Other X managers have similar tools.

Ask yourself the question, "Why are games installed on the system?"  If there 
is no reason to have them, uninstall them, that way your pupils can't play.

To stop your koha user from surfing the web, you need to look at url 
redirection - basically every url entered gets redirected to your koha site. 
Again there is lots of info on how to do this on the web.
