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. 🗺️ MORE TO COME A sixth world is already on the map, marked "Coming Soon" for a future free content update. 🛡️ MADE TO BE CALM, PRIVATE AND FAIR No Ads: Pure, uninterrupted gameplay.
