Paper Physics

Get the ball past the finish. How you solve the page is up to you. Choose an item from the shelf and click to place it, or drag it straight onto the page. Lay down planks, pin a moving board into a pivot, launch the ball with a spring, or erase an obstacle to clear the way. Every level also provides one extra fixed guard. It starts upright and can be rotated to stop the ball, bridge a gap, or reshape a route. Press play and the puzzle stays editable. Place, move, and erase while the ball is rolling to correct its path in motion. Run Again keeps your construction; Start Over restores the whole level. Undo and redo make experimentation easy. Collecting blue stars opens ability choices. Bounce, glide, impulse, an extra plank, jump, brake, and reverse appear gradually, offering new options for different situations. Sticky hazards and multi-floor layouts keep changing how each route behaves.
