Most of you have probably played around with Line Rider before, and with good reason. It's simple, thoughtful (or mindless, depending on your mood) fun.

But why just draw courses for one lonely schlub on a sled when you can scribble roller coaster runs for 8 unlucky guinea pigs?

There is a "goal" to the levels in Roller Coaster Creator. At your disposal are a freehand track pencil and special pieces like chain lifts and loops.Use them to design your track in such a way that you collect enough coins to reach the target on your meter.

It's also fun to draw totally impractical tracks and watch the little guys bounce hopelessly around as the cars topple over each other. As a bonus, there's a speedometer so you'll know just how quickly your train is hurtling toward the ground.
