I'm pretty easy to please when it comes to iPhone games. For example, I've had Monopoly [App Store] on my iPhones since the app first appeared, and so far I've played 201 games. My other favorite? Apple's Texas Hold'em. So why would a shooting app be interesting to me?
iShotgun Pro [US$1.99, App Store] is a fun little shooting game from developer Yossi Malki in which you use a pump-action shotgun like my trusty Remington Model 870 to shoot clay targets. You go through 15 timed rounds shooting at single and multiple clay targets or falling bullseyes and bombs. There are three different levels of play so you can build your skills.
Just like in real clay pigeon shooting, you can yell "Pull!" to have the targets launched. There are also ways to launch the clays automatically or by tapping a button on the screen. You get different point levels for hitting various colors of clays, and try to avoid the black targets which reduce your point total. In the rounds where bullseyes and bombs are dropping, you need to avoid hitting the bombs. To aim, you can either use the iPhone's accelerometer or just tap where you want to shoot.
