The games all use fairly simple -- even rudimentary -- graphics, but they heavily leverage the iPhone's accelerometer to provide immersive action for iPhone and iPod touch gaming enthusiasts. With iGolf, you pick a club, find a hole on a course (or go to a driving range), and swing using a realistic motion.

iBowl follows a similar motif -- you swing your iPhone or iPod touch to throw a ball down a lane towards ten pins, knocking over as many as you can.

And the newest game, iBaseball, lets you play an inning of baseball as the pitcher and a hitter (must be the National League, then). You can pitch to three batters with either a fastball or curveball, then you can try for as many hits as you can in a single inning.

SGN CEO Shervin Pishevar said in a statement that his company has a "pipeline" of games planned for the iPhone through the end of the year, along with updates to existing games to improve gameplay. The company also wants to leverage social networking by having gamers participate in a Global Leader board which lets them compete against one another for high scores.
