A lot or a little?
Parents need to know that RollerCoaster Tycoon Story is a puzzle game for iOS and Android devices. The game is a spinoff of a long-running franchise that centered on building a theme park. The action here primarily involves playing matching games, although as gamers advance levels, they'll help fix up the amusement park and access new areas. The app is free to use, and players can fund some activities involved with currency they earn while playing. But the app also sells a number of items to advance gameplay that cost real-world cash, with packages ranging from $.99 to $99.99.
