The Incredible Machine

Build wild Rube Goldberg contraptions from balloons, cats, gears, and gravity to solve each devious puzzle — The Incredible Machine costs nothing here, installs nothing, and asks for no account. Sierra's inventive 1993 physics puzzle game loads in seconds and challenges you to combine quirky parts into chain-reaction machines. Touch works after a fashion, but this is a game of dropping a part on an exact spot and then nudging it a hair to the left, which is what a mouse is for.

How to Play The Incredible Machine Online

Your first puzzle is a few seconds away:

1. Press Play to boot the game and reach the puzzle menu.
2. Wait for the title screen to finish drawing, then pick a puzzle from the list.
3. Click inside the game frame so your clicks and drags land in the puzzle rather than on the page.
4. Read each puzzle's goal, then drag the provided parts into the play area to build a solution.
5. Press start to run the machine and watch your contraption spring into action.

The Incredible Machine rewards experimentation — try ideas, run them, and tweak until the chain reaction works.

Controls

The Incredible Machine is played almost entirely with the mouse:

Run your machine often as you build — watching it play out shows you exactly where the chain reaction breaks down.

What Is The Incredible Machine?

The Incredible Machine is a physics-based puzzle game developed by Jeff Tunnell Productions (Dynamix) and published by Sierra in 1993 for MS-DOS. Each level presents a goal — pop a balloon, get a ball into a basket, scare a cat — and a collection of parts. Your job is to arrange those parts into a working Rube Goldberg machine: an elaborate chain reaction where one action triggers the next until the goal is met.

The game is celebrated for its creativity and charm. Its toolbox of parts — conveyor belts, gears, ropes, pulleys, seesaws, balloons, fans, mice, cats, and more — interact through simulated gravity and physics, often in funny ways. With dozens of clever puzzles and a freeform mode for building your own contraptions, The Incredible Machine became a beloved classic that sparked a whole genre of physics-toy puzzle games.

How the Game Works / Gameplay Basics

Every puzzle gives you a goal and a limited set of parts in a tray. You place and connect those parts in the play area to build a machine that, once started, runs automatically and (if you've built it right) achieves the goal through a cascade of physics interactions. A ball rolls down a ramp, lands on a seesaw, launches a weight, pops a balloon — each piece setting off the next.

The challenge is figuring out how the parts combine: which surfaces redirect a rolling ball, how a fan moves a balloon, where a cat will run when a mouse appears. You can run the simulation as often as you like, observing where it fails and adjusting placements until the chain works end to end. Some puzzles have fixed parts you must work around, and many have multiple valid solutions. A sandbox "freeform" mode lets you build contraptions with no goal at all, purely for fun. It's pure creative problem-solving.

Beginner Tips

• Read the goal first. Know exactly what the machine needs to accomplish before building.
• Run early and often. Testing shows you where your chain reaction breaks down.
• Learn each part. Understand how balloons, fans, gears, and animals behave before relying on them.
• Work backward. Start from the goal and figure out what must trigger it, then build toward the start.
• Mind gravity and angles. Ramps and surfaces redirect rolling objects — position them carefully.
• Don't overthink. Many puzzles have simple solutions hiding behind the clutter.

Why Play The Incredible Machine Online?

This game invented a genre, and then most of that genre moved to phones and left the original behind. Coming back to the Sierra release used to mean a floppy install and a mouse driver loaded in advance before the tray of parts would even appear. Now it's a link, it's free, and nothing stays on your machine afterwards.

That matters more here than it would elsewhere, because the whole game is small experiments: place a part, run it, watch it fail, move the part two inches. Being one click away from the next attempt is the point — as true if you are rebuilding puzzles you half-remember from 1993 as it is if you have never watched a cat chase a mouse into a fan.

Troubleshooting

• Game won't start? Reload and let the title screen settle before you start clicking your way into the puzzle menu.
• Mouse or keyboard not responding? Click once inside the game frame — the game draws its own pointer, and it only follows your hand while the frame has focus.
• Parts hard to place? Use fullscreen mode for a larger, more precise play area.
• Running slowly? Crowded contraptions with dozens of moving parts work the simulation hardest, so close other tabs and heavy applications before you build something elaborate.
• No sound? The clangs, boings, and animal noises are how the machine tells you what just happened, and they matter most when a part fires outside the visible play area.
• Machine not working? Run it, watch where it fails, and adjust one part at a time.

Frequently Asked Questions

Is The Incredible Machine free to play online? Yes. There is no charge at any point — not to open the first puzzle, not to reach the later ones, and not to use the freeform sandbox.

Do I need the original floppies or a DOS setup? No. Everything runs inside this page — no disks to find, no DOS install, no registration.

Can I play The Incredible Machine on mobile? It loads, but the game is built on dropping a part exactly where you want it and then shifting it slightly, and a fingertip is wider than most of the gaps you'll be aiming at. A mouse is the right tool here.

Is this the original 1993 Incredible Machine? Yes — the Dynamix original, the one the sequels and the wider physics-toy genre grew out of.

What kind of game is The Incredible Machine? It's a physics puzzle game where you build Rube Goldberg-style machines from quirky parts to solve each level's goal.

Can I save my progress? Yes. The game tracks which puzzles you've solved, and you can save an unfinished contraption from the menu and return to it later.
