Subscribe to Pocket Gamer on Perchang, the new puzzler from ex-Rodeo Games alum, is available now on iPad and iPhone.

Your goal is simply to transport marbles to the waiting exit funnel, but doing so requires you to coordinate various machines and contraptions in each of the game's 60 levels.

Machines are colored red or blue, activated with the same-colored buttons, so solving Perchang's puzzles is an exercise in using magnets, portals, and other devices at the right times.

You can find Perchang on the App Store for £1.49 / $1.99.
