Draw the hills, dips and ramps yourself, then watch a sled rider careen down your sketch under real gravity and momentum.
You build the course by drawing lines. The rider rides whatever you sketch, accelerating downhill, carrying momentum over jumps, and slowing on the climbs. Place a flag or goal and craft a track that carries the rider there — decorative scenery costs nothing, so doodle freely.
Slope Sketch recreates the draw-a-track sandbox of 2006 — sketch a line and watch a sled rider run it under gravity and momentum, somewhere between toy, puzzle and physics experiment. A simple idea that became a creative web phenomenon.
Slope Sketch is an original free browser physics toy in the draw-your-own-track tradition, with a daily puzzle and an open sandbox. No download needed.
