The self proclaimed 'hardest riddle on the internet'. Over 139 fiendisly difficult levels of a crazy internet based game where the object is to progress from one level to the next by solving the riddle hidden somewhere in each page.
The levels are represented on screen by an image with a small number in the top left representing the level you are currently on. using only your wits you must find the next screen by whatever means possible (outside of using internet spoilers).
So far it has me foxed already on level 8 (and I had help from my housemates). Be warned however that it may consume your life so if you really want to do that revision its probably best not to click.
On the other hand it may be just the stimulus you need to get that thinking engine back on track.
Swings and roundabouts.
