The iPhone and iPod Touch version of the cult classic Flash game "Line Rider" is every bit as enjoyable on the slim, slick phone as it is online. The nearly identical controls let you draw a track for Bosh the sledder to ride once you press Play. An eraser tool and infinite undoes make it easy to adjust a deadly pitch, and the flag button helps you mark a new starting place for your rider, so you don't have to start at the beginning each time you test a length of track.
Creating a route can be time consuming, thanks to the continual trial and error that novices and poor engineers will undoubtedly experience. That, combined with the game's purposely stick-drawing graphics lend "Line Rider" a scrappy air that is nevertheless compelling, even in contrast to the iPhone's sophisticated graphical capability. Having to pan around the iPhone's small screen size is our biggest complaint; our loudest praise goes to uploading prize courses to share and downloading others' masterpieces to play on our iPhone--or attempt to pass off as our own.
