It is clear that you cannot remove games from the Internet itself. But it is necessary to make sure that users cannot play them instead of work or study. This can be done in different ways.
Instructions
Step 1
Try to use a radical method - uninstall Flash Player. Without it, almost all games designed to run directly in a browser will stop working. If users are not in administrator mode, they will not be able to reinstall Flash Player. But do not do this if users need to run any Flash applications, for example, watch instructional videos on YouTube.
Step 2
If you cannot uninstall Flash Player for any reason, disable plugins in your browser (all or individually). The way to do this depends on the browser. For example, in Opera - "Tools" - "Options" - "Advanced" - "Content" - uncheck "Enable plugins", in Firefox - "Tools" - "Add-ons" - "Plugins" - select the Flash plugin and click " Disable ", in IE -" Service "-" Manage add-ons "-" Add-ons loaded in Internet Explorer "-" Disable ". In Chrome, there is no way to disable the Flash plugin by default, for one to appear, install the official extension called FlashBlock.
Step 3
The Opera browser allows you to block the use of plugins only for certain sites. To do this, go to the site on which you want to disable the use of Flash, press the "F11" key in the old version of the browser, and the right mouse button in the new version, and in the context menu, select the "Site settings" item, open the "Content" tab and then uncheck the "Enable plugins" checkbox.
Step 4
The most complete assurance that users will not waste time playing games can only be provided by using an external firewall. If you use a separate computer instead of a router, configure such a firewall on it. Just enter the URLs of those sites that host Flash games to the blacklist. After that, users will not be able to visit them regardless of OS, browser, settings and Flash Player.
