Hi...my dad wants to play chess (or other games) online to cheer up my ds6, who's really unhappy and 2000 miles away from his grandparents. B/c of the way my son's already clicked his way onto dating sites and totally inappropriate images/videos, generally accidentally or in the spirit of innocent exploration, I don't trust he will stay exactly where I put him online, and don't really want him on a gaming site where he can talk with strangers at this age or click on ads that take him who knows where. (and with two younger kids I can't monitor him every minute to be sure he's ok). Does anyone know of a site where ds can play with his grandad without ads or contact with unknown people?

thanks for any suggestions!
