Zip-Zap is a puzzle game that asks users to solve puzzles using Rube Goldberg-style hinges and levers that are put into place via well-timed taps. There are more than 100 levels to complete, and the game has no ads or in-app purchases.
Zip-Zap will be available for free until next Thursday, when a new App of the Week will be chosen. It can be downloaded from the App Store. [Direct Link]
