There's a soundtrack to the game--the peppy music that plays under the highlights of ESPN's SportsCenter program. You can mute that sound if you find it annoying--if you're like me, you will rather quickly--though you'll still be able to hear the camera clicks and the crowd jeers.

The game remembers your scores, which you can sync online to see how you compare to other players. (I compare quite poorly, thanks for asking.) The score-syncing feature requires you to set a user name and e-mail address and, of course, to be connected to the Internet. The price of being connected is that a short ad appears when you launch ESPN Cameraman and when you conclude each game. That doesn't happen when you play the game offline.

ESPN Cameraman offers a fun enough way to pass the time, particularly if you enjoy the Spot the Differences concept. I wish the game would provide more of a countdown at the start of each level--instead, the images appear and the timer starts running down immediately. Some of the differences were a little hard for my 36-year-old eyeballs to identify on the iPhone's screen--I find crowd shots in which one fan, seated among multitudes, is wearing a different shirt in one of the images particularly maddening--but I suppose that's part of the challenge.

My biggest complaint with ESPN Cameraman is that the more you play, the more likely you are to come across the same images. There's a shot of three Arizona Cardinal fans--perhaps the entire Arizona Cardinal fan base--that must have appeared half-a-dozen times in the course my testing this game. That makes ESPN Cameraman less about your ability to spot differences and more about your ability to memorize the differences you've already spotted, which sort of defeats the purpose. The most recent update added 10 new photos, according to the game's App Store page, and since many of the photos are from recent events like the World Series or the just-completed college football season, I assume that EpicTilt and ESPN will introduce new images fairly regularly.

Complaints about repetitiveness aside, ESPN Cameraman is a clever take on the Spot the Differences genre and just the sort of casual game that you can pick up and put down as the mood strikes.
