Parents need to know that Two Spies is a strategy game for iOS devices. Players can test out a sample round before they officially start playing to get some guidance on how the game works. They're also able to view written descriptions of the various moves they can make during the game by clicking on each item, which reveals a brief description of what's involved. The gameplay centers on trying to attack an opponent, but players will first need to use a number of logic and other skills to find the other spy. When they choose to strike because they think they know where their opponent is, a knife appears on the dot that marks the city they're in, which presumably is meant to indicate they're trying to stab the person. That's not shown specifically, though, so gamers don't see any blood or sign of physical injury. The app offers some paid items -- spy character pins for $0.99 or a season pass for $3.99, which provides different pins, game stats, and other playing extras. But players can easily use the app without buying them and those items aren't heavily promoted.
