A lot or a little?
Parents need to know that Phase 10: World Tour is a card game for iOS and Android devices. In the vein of Uno and rummy, this has you trying to get rid of all of your cards by putting them in the appropriate piles. As such, it has no objectionable content. Even when you play against another person online, there's no communication between players. Players use in-game currency to play, which can be earned by playing or watching ads, or by purchasing packs from the in-game store with real money. Read the developer's privacy policy for details on how your (or your kids') information is collected, used, and shared, and any choices you may have in the matter, and note that privacy policies and terms of service frequently change.
