How to block online games from Vkontakte?

Question

Computer networks

Hello!
There is a computer class at the school.
There is a task to restrict students' access to online games from Vkontakte, without restricting access to the Vkontakte site itself. Flash Player is also desirable not to touch, it is sometimes needed in the learning process.
The network in the class is built on the basis of a simple Asus SOHO router. In the near future, it is planned to install the AD server and the ZeroShell server (thanks to the user curlydevil for the tip)

Answer 1

vkontakte.ru/app* blacklisted?

Answer 2

Block VKontakte games and applications: Block
these addresses, for example, in Eset antivirus
*vk.com/app*
*vk.com/al_apps.php*
*api.vk.com/api.php*
*vk.com/api.php*
* needed to block long links...
and put a password on the antivirus.

Answer 3

Perhaps this is not so convenient, but since access to VK is needed only at a certain time, you can set up access to the entire VK on a schedule.

Answer 4

Block flash only for vkontakte?
In the same chrome, restrict all plugins except certain domains. I'm sure there are extensions for convenience.
Well, or raise something TMG-like, you can set it up quite simply there.
