Clash Royale allows players to communicate with each other through unmoderated chat features. As a result, many app reviews by parents and children describe encountering abusive, hostile and explicit language while using the app. They also report witnessing users exchanging personal details through the app - so it is important to talk to your child about keeping their information secure. Parents suggest only allowing children to form "clans" with real life friends, and joining with their own parent account so that chat within the clan can be monitored. A further grievance related to this app is that it is difficult to make progress without spending money, and so this style of gameplay often results in anger and frustration among younger users. Please ensure that in-app purchasing is restricted through your child's device before they play this game.
