Instructions
Go to the "Line Rider 2" official website (see Resources).
Click "Play," then "Continue."
Click on a color box at the top of the screen. The colors that are available are blue, green, red, brown and pink. Blue lines are the lines that the riders go on, green lines are for decoration, red lines speed up lines, brown lines make riders go slower and pink lines cause trapdoors to appear under the riders.
Draw a line using the mouse cursor. Press the triangular "Play" button to play the game.
