IGN writes: "There's something about previously free games going into pay-for-play that doesn't sit well with me. Line Rider was a famously free game before it started moving to mobile, iPhone, DS, and other platforms. For gamers used to playing it for free, shelling out $3 for the iPhone edition might not seem like a good deal. However, the iPhone edition does add new features, such as community sharing, that makes the new price tag easier to swallow.
If you missed out Line Rider before, here's the premise: You draw a series of lines in any configuration you want and watch your sledder ride the lines. But it's tricky; if you mess up on the angles or lines of descent, your sledder will fall off. So it's up to you to see how big and/or crazy you can make the course from a wealth of drawing options. Choose the pencil and your type of line (regular, accelerated, or scenic) and start drawing your course. Use the Line tool to draw straight lines. An eraser removes whatever part of your track you wish, and the undo button cancels the last line you drew. The hand icon lets you move the playfield around. You can also zoom in and out of the playfield using the same finger pinches to zoom in and out of Safari. The play button starts your ride, Save saves your track for upload to other players, and the trash icon lets you start over. These basic tools are easy and intuitive, but the on-screen icons are easy to accidentally touch while drawing a course."
