Your challenge is to manouvre the black dot to the red square without ever turning left, or making a U-turn. Harder than it looks. Maze No.1 can also be found in the Maze Gallery. Maze No.2 is an 'open' maze based on the same rule. An illustration of a mechanical no-X-turn maze is also shown below
New July 2005: Two new mazes added, designed by Palmer Mebane.
No-X-turn mazes were first offered to the public in the lates 90s 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-thru mazes, and see some photos, here at Robert Abbott's site.
