PuzzleRig: Physics Machine Lab

Place a part. Press Play. Watch it work.

PuzzleRig: Physics Machine Lab is a calm, offline physics puzzle game about building small machines and Rube Goldberg contraptions.

Each level presents a ball, a goal, and a selection of mechanical parts. Drag parts onto the board, press Play, and real physics decides what happens: the ball rolls, a lever tips, a swing knocks a domino, a spring throws, or a cart drives off with its load.

Whether you enjoy engineering puzzles, brain teasers, or experimenting in a physics sandbox, PuzzleRig gives you total freedom to test your logic at your own pace.

🛠️ HOW IT PLAYS
• Drag & Place: Position parts from the tray onto the board. Turn ramps and pads with their handle; wheels and weights snap into place.
• Experiment & Refine: Press Play to run your machine, Reset to change it. Your build stays where you left it.
• Visual Trajectory Feedback: A dotted trail shows where the ball went last time, making it easy to fine-tune your contraption and learn the mechanics.
• Gentle Hints: Stuck after a few tries? A hint bulb lights up and outlines one part of a working machine.


⚙️ FIVE WORLDS, 55 LEVELS
• 🧪 Gravity Lab: Ramps, ice, rubber, slopes, and friction.
• ⚖️ Lever Works: Weights, pivots, torque, and balance.
• 🔔 Swing & Smash: Pendulums, dominoes, and bells.
• 🌀 Spring Yard: Spring pads, bounce angles, and launchers.
• 🚗 Machine Shop: Wheels, motors, and carts that carry their load.

Each world starts gently and then asks for real thinking. The last levels of each world bring together every part the world has shown.

⭐ THREE STARS A LEVEL
• Solve the puzzle: Reach the goal using your machine.
• Optimize your build: Use as few parts as possible.
• Find the bonus: Discover hidden solutions.
•💡 Bonus Science Notes: Every solved level unlocks a short note explaining the real-world science and physics principles behind your build.
