Parents need to know that Cookie Run: Kingdom is a role-playing game for iOS and Android devices. Players need to participate in battles to earn the currency that's used to build things in the town and level characters up. The battles involve cookies and other characters, though -- not human beings -- and no blood or gore is shown. Players will primarily see flashes of light as characters strike, and defeated foes are hurtled off screen. They'll also see some mentions of other games in static ads that are shown during transitions in the game, but there isn't a ton of overt advertising. While players can purchase items with coins, another type of in-app currency, crystals, can be earned by playing or bought in packages that cost $0.99 to $99.99 in real-world cash. Players may find they don't need to purchase any extra items, though.
