Contraptor

Contraptor is a Rube Goldberg physics playground where you build machines to solve hand-crafted puzzles. Drop in rods, wheels, pins, motors, and welds, wire up a contraption, hit Play, and let real physics decide how it works. NEW TO BUILDING? START WITH PLAY. Thirty short levels teach the whole game one trick at a time. Your first level hands you a single oval. Thirty levels later you're wiring motors, bracing with ghost rods, and threading payloads through wormholes. Every level keeps the machine you built to beat it, so you can come back and watch it run. Beat them all and you earn a Certificate of Completion with your name on it. THEN TAKE ON THE COMMUNITY. Every challenge is a puzzle: get the payload (or many payloads) to the target(s) using whatever that challenge allows. Some let you shove pieces around, some ration your parts with Twists, some bend the rules with wormholes.…
