One of the most charming Flash games I’ve played is the elegantly simple Line Rider, a monochrome time-waster in which players draw a slope and watch a stick man ride down it on a sledge.

Its popularity has seen it turned into a PC, Wii and DS title, blessed with a little more polish and backed up with a website that enables players to post their top tracks. If you fancy trying the original before you buy, visit linerider.com to get a taste.
