Line Rider is the new time waster of choice in our house.

A simple concept – draw a line on the screen from top left to bottom right. Press Play and a tiny tobogganer rides down the line you have drawn. Make the line steeper to give him more speed – not too steep or he’ll over-balance and crash. Add some bumps, jumps, and loops. You too can spend hours making convoluted mountains for your man to traverse. Share your creations on YouTube and let others marvel at your talents, and your wife marvel at why it is taking you so long to do the 2003 tax return.
