Unblocked games are online games that would normally be blocked, or censored, on a school or office network. By navigating to a proxy site, a person is able to open, or unblock, these games without the network noticing.
Many businesses and school districts restrict access to malicious or otherwise inappropriate websites on their networks. However, a variety of proxy sites offer access to free flash games. Many of these sites advertise specifically to children as a free and fun way to play games at school. Although these games are normally blocked on the network, the proxy server acts as an intermediary in that, to the network, it appears that the user is simply browsing the proxy site when he or she is actually playing games.
