When they are not enough, use mechanical contraptions to lift, push and steer your marbles. Use a variety of shapes and materials to bring your creations to life. Get started easily with the snap in place system, and turn it off when you want to go beyond the trodden path. Build marble runs where your imagination is the only limit. Still can't find the right style or function of a piece. Then you can build your own. Marvelous Marbles is meant to be modded and comes with Steam Workshop integra.
