I opened this file up in a hex editor and started poking around. "undefined.sol" contains all your Line Rider tracks. The directory will contain a file called "undefined.sol".

It will vary depending from what web site you loaded Line Rider flash file. On Windows, Shared Objects are stored under the \documents and settings\username\Application Data\Macromedia\Flash Player\#SharedObjects directory. Line Rider stores its track data using a Flash Shared Object. I chose this one because there is supposed to be a new version of Line Rider due out very soon - once this happens this information will be totally useless, instead of just mostly useless. The Line Rider File Format is the first such post. In an effort to get some more posts happening around here I've decided to unleash a few of these 1/2 finished projects. I mostly figured it out - but owing to my extremely short attention span it quickly entered my immense "1/2 finished projects" repository. The idea was to add a much required "erase" function. If you've ever found joy from toppling a row of dominoes then head over to our Downloads section and get on the Line Rider bandwagon.A while back I tried to "reverse-engineer" the Line Rider shared object - the file that stores your Line Rider Tracks. We found it great fun to discover other people's creations, but there's also a lot of fun to be had trying to one-up everyone else. Thousands of YouTubers have uploaded videos of their best Line Rider tracks and the amount of effort that goes into some of them is staggering.


Sounds pointlessly simple, and indeed it is, but an estimated six million people have downloaded the thing in the last month alone, placing it at number seven on Google's most searched terms list - according to its creators at deviantART. The game's rudimentary physics engine lets players concoct elaborate tracks that become as addictive to create as an intricate, winding line of collapsing dominoes. It's been a while since we've seen anything worthy of relentless play, but we've just spotted a true contender for 'the next big Flash thing' in Line Rider, a Flash 'toy' that lets you draw ramps and slopes for a virtual sledder to ride on. In the late 90s it was Xiao Xiao (Stickman), then the Hampster dance and the Happy Tree Friends. Every so often geek-kind will conjure up a piece of genius that takes the Internet by storm.
