Line Sledder is a line-drawing physics game you can play right here — no download, no sign-up.
Draw a line, press Play, and a little sledder in a red scarf rides whatever you drew. Gravity does the rest: steep slopes build speed, ramps launch you into the air, and a bad landing sends the rider tumbling off the sled.
Three kinds of lines
- Track lines (blue) are the ground. Lines drawn left to right are solid on top; draw right to left and you get a ceiling instead.
- Boost lines (red) push the sled along the direction you drew them. Use them to climb hills or launch big jumps.
- Scenery lines (green) are just for decoration — trees, signs, clouds. The sled passes straight through them.
Free ride
Start from the sample track or clear it and build your own: long downhill runs, ski jumps, half-pipes, boosted climbs. Use the pencil for curves and the line tool for clean ramps; new lines snap to the ends of existing ones so your track stays smooth. Zoom and pan to build tracks thousands of pixels long.
Eight challenges
Each challenge level has stars to collect and a limited amount of ink. Collect every star without falling off the sled to clear the level. The early levels teach the basics — slopes, valleys and walls — and the later ones ask for boost lines, U-turns, mid-air catches and long leaps with almost no ink at all.
