A4 workshop challenge

A4 workshop challenge is a puzzle game that turns a plain sheet of paper into a miniature engineering lab. Each level drops you onto a blank A4 page with a fixed set of mechanical parts—gears, rods, cams, and pistons—and a clear objective. You might need to lift a weight, spin a wheel, or push a piston to a certain point. The catch is that every component must stay within the paper's edges, so space management is as important as mechanical logic. The real appeal lies in experimenting with different layouts. There's rarely just one solution, and you'll often find yourself rearranging parts to discover a more elegant path. The game rewards careful observation: a gear that seems useless might be the key to connecting two distant mechanisms. With each puzzle, the components get more complex, but the core challenge stays the same—can you make everything click together on just one sheet of paper?
