Mechanical puzzler Zip-Zap goes on sale for free for the first time
Simple machines
One tap is all you need to control the mechanical creations of Zip-Zap, the colorful puzzler currently available for free on the App Store.
One tap and the gears and springs that control the various machines in Zip-Zap come to life, compressing when you touch and expanding when you release. Those simple controls let you snake and flip clumsy robots through obstacle courses, climb up towers of pegs, catapult balls across gaps, among other physics-based puzzles.
To try those simple yet diverse challenges, you can download Zip-Zap on iPad and iPhone.
