No left turn mazes

Your challenge is to find a route for the black dot to reach the red square without ever turning left, or making a U-turn. Harder than it looks!

The original and yet more no-left-turn mazes are currently available implemented in puzzlescript (credit: Dario Zubovic & Jack Kutilek)

Here is a photo showing a mechanical version of a No-X-turn maze (in this case a no-right-turn maze). It was made by Oskar van Deventer and based on Adrian Fisher's Jammed Tractor design. A special half-moon shape under the tractor prevents it from turning right or backing up.

Here is a full-size no-right-turn maze of my own design built using reconfigurable decking squares that simply click together and can then be boxed up again for easy storage. This one was built for a house-warming party in July 2005.


No-X-turn mazes were first offered to the public in the late 1990s as full-size walk-round mazes to accompany maize-mazes in the USA and UK. They are most frequently built using bales of hay. You can read about all types of walk-through mazes and see some photos here at Robert Abbott's site.
