MarbleTrail

Your world becomes the course. MarbleTrail is a fast, local marble-racing game where every race changes. Choose a competitor pack, launch a field and watch marbles collide, ricochet and fight through long scrolling courses packed with rails, funnels, bumpers, gates and moving hazards. Turn on Live Cam to place a dim real-time camera view behind the board. MarbleTrail highlights usable edges from the scene and turns selected shapes into temporary obstacles. Snap the current view or choose several photos, then watch their structure weave into the race without stopping the action. Camera and photo analysis happen on your iPhone. Shape the race in the moment: - add a bumper; - fire a gust; - trigger a satisfying quake; - physically shake your iPhone to free a jammed field; and - pinch the course to change your view while the camera keeps the leader in sight.
