A lot or a little?
The parents' guide to what's in this app.
What parents need to know
Parents need to know that Subway Surfers is an endless-runner game, much like Temple Run, but one that is much more lighthearted. Set in a train yard, players can run into oncoming trains, but no blood or gore is shown -- and collisions with obstacles just results in you being caught by the guard. While in-app purchases are available, they're not thrust upon players and aren't really necessary, since earning coins is easy in the game. Players on iOS devices can share high scores via the Game Center social network, but participation is optional.
What's it about?
Like most endless runner games, there's a threadbare plot to Subway Surfers. You run, trying to dodge capture and obstacles, swiping up to jump or down to slide. Swiping side to side lets you switch tracks as you run. Along the way, players collect coins, which can be used for power-ups, but those same power-ups are also sprinkled along the tracks.
Is it any good?
There's really nothing particularly new about Subway Surfers. Like Temple Run, the point is to run endlessly to avoid capture. But it's still an immensely entertaining game. That might be because of the bright setting and happy characters. It could be due to the dense number of power-ups you encounter as you run. It could be the streamlined control scheme that takes the best from other games and leaves out the complicated parts.
Ultimately, it doesn't matter why the game is so fun. You'll be too busy playing, then playing again -- and again -- to overthink it. It expands on a formula that was in danger of becoming stale and makes it fun all over again.
