The Enjenir: The Engineering Physics Building Simulator
Put your engineering and problem solving skills to the test in this sandbox physics building game!
Want something that feels chaotic and replayable the way Rover Builder does? These games line up well for what comes next.
Build wobbly, wonderful rovers from over 100 parts and haul absurdly shaped cargo across a colorful Mars. Deliver a bathtub up a cliff, earn funds, unlock rocket engines, and watch a colony grow around your deliveries. Play solo at your own pace, or grab up to three friends for co-op chaos.
Chaotic, Replayable, Relaxing
A sandbox for mechanically minded builders: snap together motors, gears, springs and joints to make cars, cranes, walking machines or a fully working engine, then drive them and smash them to bits. Physics keeps everything honest, and the workshop is full of machines other builders made.
Chaotic, Replayable, Relaxing
Put your engineering and problem solving skills to the test in this sandbox physics building game! Enjoy the freedom of completely gridless 3D sandbox building combined with hilarious ragdoll third person controls, offering a truly unique and hilarious "Enjeniring" experience!
Chaotic, Replayable, Relaxing
Build robots of any shape, from eight-legged spider bots to odd flying saucers, then program every move with a visual tool instead of code. Race them, throw them at obstacle courses, or build worlds with up to three friends and see whose creation survives.
Chaotic, Replayable, Relaxing
Design a car from nothing: frame, suspension, steering, all of it. Real soft-body physics means beams bend, tyres squish and bad ideas fold spectacularly. Build in the sandbox, race on generated tracks, then rebuild it better. For tinkerers who think a broken axle is a good afternoon.

RoboCo is a sandbox game about designing and building robots to serve the needs of squishy, hapless humans in the world of tomorrow!
Chaotic, Replayable, Relaxing
Build a car, boat, plane or whatever should not work, then take it across deserts, oceans and space. Trailmakers is a bright physics sandbox with a frog-rescuing campaign, rough multiplayer battles and races, made for tinkerers who like rebuilding until it finally flies.
Chaotic, Replayable
Pilot flying bulldozers, rocket tanks and grappling-hook ornithopters through a physics playground where every wall, tower and silo comes apart piece by piece. Demolish 50+ campaign missions, chase high scores, or build your own wrecking machine and raze a sandbox at your own pace.
Chaotic, Replayable
Unleash your creativity and craft anything from flying cars to jet-powered toilets.Fair warning: there's a learning curve. But once you've got it, the sky's the limit for your creations!While active development is paused, we focus preserving the game and keeping it accessible.
Chaotic, Replayable, Relaxing
World of Contraptions is a physics-based building game in which you build the most varied contraptions to solve the most diverse types of puzzles. Win dozens of levels with different types of obstacles. Design the best contraption for each challenge using a giant collection of blocks.
Chaotic, Replayable, Relaxing
Create, Collect, and Crash in Autocraft, a physics destruction sandbox. Create your own cars, rockets, tanks, planes, boats, and more.
Chaotic, Replayable, Relaxing
Besiege is a physics building game about medieval machines with one job: annihilation. Bolt together cannons, spinning blades, wings and far too many wheels, then send your creation off to flatten castles and armies. When it works, it is glorious. When it falls apart, that is usually funnier.
