Clockwork is a take on the standard puzzle game of freeing an item from a set of interlocking pieces. However, what makes clockwork unique is that all the pieces move at the same time in synchronized speeds, much like a clock.
The game consists of three sets of ten levels, each with a different level of complexity. Within each set, player must successfully complete a puzzle in order to unlock the next. There is also an optional tutorial consisting of five levels that outlines the basic mechanisms encountered in the game.
The goal of each level is to reorder the pieces in such a way that the golden gear in the center can escape the screen when "launched". Pieces are controlled using the buttons on-screen, or using the keyboard shortcuts shown.
