CSS DEMOSNo Left Turn Puzzle - Purely for fun

Date : 6th December 2011

For all modern browsers

This demo is too wide for your mobile screen.
Please view on a tablet or PC.


It has been 3 years since I last produced a puzzle made entirely using CSS so I thought that I would use the latest techniques to produce this version of the 'no left turn' puzzles that have so far been done using javascript.

This is a pure CSS version that cannot be done by 'cheating'.

So click the 'home icon' in the bottom right of the maze to start and then make your way to the lightbulb by clicking on any junction either ahead of your current position or to the right if at a junction with a right turn.

You cannot turn left.

If you end up at a corner with no right turn then your arrow icon will change to a bag with a white cross, indicating that you must start again.

When you reach the lightbulb it will light up.

I have added a small jQuery routine to stop the relative :targets from being added to the browser history for Firefox, Chrome and Safari.

Because of all the time and effort spent in producing this demonstration I would ask that you respect my copyright.
