A lot or a little?
Parents need to know that Puzzle Combat: Match-3 RPG is a puzzle game for iOS and Android devices. Players can buy various packages of gold for $4.99 to $99.99 to be used in the game, but you can also earn gold through play to use on other types of in-app currency and items. They can, for instance, spend gold to purchase food if they don't have the amount of it that's required to train and level up heroes -- which helps reduce the need to spend any real-world money. The number of elements the app contains, ranging from items that are crafted to use in combat to the structures and process involved in training, may end up being a larger issue because some things aren't explained in detail. There are also some violent elements in the app. Numerous guns are given as rewards, and characters have unique battle skills, such as the ability to conduct an anti-armor strike, that are used in matching games. Players' opponents, though, are mythical creatures like zombies, not humans.
