Whilst players fight against opponents in Castle Cash, there is no overly graphic or realistic violence. However, this app supports group and private chat features (including voice chat), and so parents should be aware that children may be contacted by strangers. It is essential to talk to children about safety in these situations. In any app where players interact anonymously there is the potential for children to be exposed to profanity, abuse, adult content and hostile language. App reviews show players have reported being approached and sexually harrassed while using the app.
