Blocking Google site games

[DK12103]

I have Disney Circle and an ORBI RBR50 and two satellites.    I'm struggling to block games on my sons computer for https://sites.google.com/view/unblockable-games.   Anyone know have experience and advice on how to block these games from being accessed?    I can't block sites.google.com since he uses that for school.     Any advice would be welcome,  right now he's winning the battle.

My impression is that most of us who participate regularly in this Orbi forum have little experience with Disney Circle.

You are much more likely to get a useful response by posting in the forum specifically devoted to Circle:
