Newton works with any object or drawing; start with a pen and paper, or any small objects you have lying around. Simply place the object/drawing in front of the screen and manipulate it to guide the falling balls into the target zones.
The more you succeed, the harder it gets! You can use simple strategies in the beginning, but as you progress through all 60 levels, Newton will challenge you with bouncing balls, accelerating platforms and fans that force you to think in new ways.
One great way to play Newton is by purchasing Osmo Monster/Creative Set.
