Rube’s Lab vs Crazy Contraptions DRAW!

Welcome to Rube’s Lab — a physics puzzle game where creativity beats brute force. Build clever contraptions, trigger satisfying chain reactions, and solve levels using logic, timing, and real physics. Create, test, improve Every level is a small laboratory. Place objects, connect mechanisms, and experiment until your setup works. Want a clean solution or a wild one? Both are valid. Features Physics-based puzzle gameplay with realistic interactions Contraption building: combine tools to create chain reactions Hundreds of ways to solve: experiment with multiple solutions Smart difficulty curve: approachable early levels, brainy later challenges Hint system when you’re stuck (optional) Satisfying reactions: knock, roll, bounce, push, trigger! For fans of If you enjoy physics puzzles, logic games, brain teasers, and creative building, you’ll feel at home in Rube’s Lab. Download and start inventing.

What will you draw to make it work? Welcome to Crazy Contraptions DRAW!, a physics puzzle game where the contraption is already built — but something is missing. Your solution. Study the level, then use your finger to draw whatever you think will make the contraption work. Build a ramp. Draw a bridge. Block a path. Bounce a ball. Drop some weight. Or come up with something completely unexpected. You have a limited amount of ink, so make every drop count. When you're ready, hit GO and watch your drawing come to life with real physics. Did it work? Great! Did everything go horribly wrong? Reset the level, try something different, and hit GO again. THREE TYPES OF PHYSICS INK Different levels give you different kinds of ink, and each one changes how you approach the puzzle. BLUE — HEAVY INK Draw it and gravity takes over. Use falling shapes, weights, ramps, barriers and whatever else you can dream up. PINK — FLOATING INK What goes down doesn't always have to stay down. Pink ink floats upward like a balloon, opening up a completely different set of possibilities. GREEN — BOUNCY INK Boing! Green ink behaves like bouncy rubber. Draw shapes that bounce, rebound and send objects flying. TONS OF PHYSICS PUZZLES Every level gives you a new problem to solve. Get basketballs, soccer balls, bowling balls and more into their targets. Guide marbles into a fishbowl. Pop balloons. Drop objects into buckets and paint cans. And discover plenty of other crazy challenges along the way. The goal may be simple. Figuring out what to draw is the tricky part. THERE'S NO PERFECT LINE This isn't about tracing the "correct" shape. Draw your solution your way. A rough little ramp might work. A giant bouncing blob might work better. Sometimes an elegant solution wins, and sometimes the ridiculous one does. Experiment, fail, reset and try again. FEATURES - Tons of hand-built physics puzzles - Draw freely with your finger - Limited ink makes every drawing matter - Three unique ink types: Heavy, Floating and Bouncy - Tons of balls, balloons, marbles, buckets and other interactive objects - Creative physics-based solutions - No timers or pressure - Easy to learn and fun to experiment with - Reset and try something completely different whenever you want Think it. Draw it. Hit GO. Then watch your crazy contraption come to life.
