Crossplay

Is Contraption Maker crossplay?

Contraption Maker is only released on one platform, so there is nothing to cross-play with.

Steam's own store page lists cross-platform multiplayer for Contraption Maker. That confirms it exists, but not which platforms pair up.

The team that created the original Incredible Machine is bringing all of the Rube Goldberg craziness to the modern age. Solve puzzles involving ridiculous chain reactions full of hamster motors, trampolines, alligators, cats, and so much more. Everything you loved about the original game is back and improved with a new physics engine, high definition art, new parts, and even online multiplayer. The game has over 200 official puzzles, and over 1,000 community creations.
