Crayon Physics Deluxe is a puzzle video game designed by Petri Purho and released on January 5, 2009.

It features a heavy emphasis on two-dimensional physics simulations, including gravity, mass, kinetic energy and transfer of momentum.

The game includes a level editor and enables its players to download and share custom content via an online service.

Published by Hudson Soft, Crayon Physics Deluxe was released for the iOS on January 1, 2009 and in Spring 2010 for the iPhone via Apple's App Store.
