“If you’re a fan of physics-based puzzlers, then you might want to check out Brain It On!, a free puzzle game for Android and iOS.

In the same vein as Crayon Physics Deluxe, you have to draw objects on the screen to help solve puzzles. You might draw a big ball to weigh down a see-saw, or knock over a glass with a giant squiggle.

Best of all, there’s no set solution to any puzzle. You just have to doodle, experiment, and dream up a unique answer to the task at hand.”
