perplexus.info :: Tricks : Block Tour

Block Tour (Posted on 2004-05-19)

In Gridland, the cities are arranged in a 4 by 6 grid:

A-B-C-D-E-F
| | | | | |
G-H-I-J-K-L
| | | | | |
M-N-O-P-Q-R
| | | | | |
S-T-U-V-W-X

A man born in A (and never ventured outside his city) has to visit a man in X but wants to take a detour to get there. He wants to visit every city but not enter any city more than once during his tour. How should his trip go?

Solution: (Hide)

Many other interesting solutions were given in the comments, but the intended one makes use of the fact that if a man was born in A, he never actually entered that city.
