How to block minecraft on ipad

[wontons]

My kids use play minecraft through downloaded minecraft app on their ipads.  For some reason when I set my Netgear router to block games, my kids can still play minecraft on-line mode without restriction.  Is there anything I can do to block minecraft app when I choose to block games on router?  Thank you.

This is not what you can do with a DNS service.  You can block only domains or a category of domains (like games).  You cannot block games or game apps.

If this game app works based on DNS hostnames, you can block these domains with OpenDNS, else not.  You had to block IP addresses, ports and protocols at the router level then.  According to a quick internet seach, port 25565 seems to be a candidate to be blocked.
