Just download the Apple Store App (linked) and scroll down the page a bit until you see it. Pretty cool game.

INKS updates pinball for a new generation. It combines the joy of pinball with skilful puzzles, and allows you to create wondrous works of art as the ball smashes around the canvas. Blocks of colour burst like beautiful fireworks across the surface, building up in vivid layers and recording a visual history of your gameplay as you perfect your score.
