Your goal in this simple yet addictive online game is to is draw a line from left to right for the small sled rider. Use pencil tool to draw a line from top-left to bottom-right. Note, that the lines you draw have direction (lines drawn from left to right act as the floor and lines drawn from right to left act as the ceiling). Use the hand tool to move the drawing area (you can also hold down the SPACEBAR while using the pencil tool to get the same effect). After you finish drawing, press the play button. Be creative and have fun!
