Simply trace the screen to create a Marble Runs!

An easy-to-use app designed for everyone – it allows them to create fun devices similar to those featured on Marble Runs (Chain reaction machine).

Use a dragging motion to draw a line and create a simple device that follows that path, and then try changing the device afterward!

The longer the straight line, the more devices you can choose from.
Have fun making your device move in many different ways!

We plan to add many more devices in the future!
