A physics sandbox in your browser. Spawn 150 props and build machines you drive from a seat, with welds, wheels, hydraulics and wires. Smash glass, knock bots over, loose a tornado or a flood on your builds, play prop hide-and-seek, survive zombie rounds, and make your own gamemodes as mods.
Patchwork is an open-source physics sandbox by Patch: a toy box with no goal, built for the browser.
New here? The first time you play, a welcome card offers a 60-second tour (grab a crate, freeze it, spawn a prop, weld two props, add a thruster, fire it) or the Modes menu. Press M any time for the modes, with a Start button on each, and for ideas to try, some with a one-click example build. By the spawn there are pads you can stand on to start a mode.
Press Q for the spawn menu (Q again or Esc closes it): about 150 props across furniture, kitchen, office, street, garden, sports, toys, industrial and nature, plus plates, beams, blocks and wheels for building, and a crash-test dummy that flops like a ragdoll. Glass, crates, melons and TVs break into pieces when you hit them hard enough. Things float in the pool, and heavy things sink.
The physgun picks anything up where you grab it: scroll to push and pull, hold E and move the mouse to turn it (Shift snaps to 45ยฐ, Shift and Alt to 15ยฐ, R stands it upright), right click to freeze it in mid-air, let go mid-swing to throw it, R to unfreeze (twice for everything). The toolgun has 30 tools. Constraints: weld, no collide, rope, elastic, axis, ball socket, slider, hydraulic, muscle, winch, pulley and motor. Construction: wheel, thruster, balloon, hoverball, keep upright, button, emitter, explosives, align, remover and duplicator. Render: light, lamp, camera, colour and physical properties (ice, rubber, super bouncy...). Wiring: the wire tool and twelve chips (AND, OR, NOT, XOR, toggle, delay, clock, pulse, counter, constant, compare, add). Right click with the weld tool for an easy weld that lines one prop up against another. Press C for the context menu and click a prop: freeze, gravity, collisions, keep upright, ignite, break, colour, mass, and Properties for everything about it.
Building: every placing tool shows a see-through ghost of what the next click makes, green where it works and red where it doesn't: a thruster with an arrow showing where the part will go, a wheel with its axle and the way it rolls, a muscle with how far it pushes. The tool card always says what the tool is for and which click you're on, and right-click goes back a step. Points snap to a grid on a part's face, turns go in 15ยฐ steps, and parts you spawn onto a part weld to it. Put a Seat on a build and press E to sit in it: its wheels, motors and thrusters answer to WASD, Space and Shift by the way they move it, A and D turn it (the seat helps it round), V shows it from behind while you drive, and a panel says which key does what. Every chair, bench and sofa can be sat on too. Key labels hang over powered parts while you build, X shows every connection, and the context menu's card lists what a build is made of. The Align tool lines one part up with another, and letting go of a held part with Shift drops it flush onto what's under it. The Blueprints tab is a library of 31 machines in four categories (vehicles, machines, contraptions and fun): a car, a tread crawler, a helicopter, a muscle walker, a 10 m ferris wheel you can ride, a counterweight catapult with a fire button, a crane with a winch and hook, a marble run, a chain reaction and more, each built from the same parts and tools you have. Each card says what it teaches and turns as you hover it; spawning one puts it in front of you with a card that says what to press, and names its parts and joints, drawn on it. The tab keeps your own blueprints too, which copy out as text. Build-alongs walk you through your first car, a rocket and a muscle walker one step at a time, with bright blue ghosts showing where each part goes (they snap your part in when it's close), and three challenges (cross the pool, deliver the crate, reach the roof) earn up to three stars.
