Robert Radford's (not to
be confused with Robert Redford) "Electromaze" is a unique - and weird - sort of
word puzzle that first appeared in this February 1966 issue of Popular Electronics
magazine. Some people have been confused about the strategy, believing that all
the white spaces needed to be filled in. They do not. Just because a letter might
have an empty square adjacent to it does not imply that another letter must fill
it. Also, read the instruction carefully, especially the part about the last letter
of one word being the first letter of another word. You will probably want to print
out the maze grid and find an old guy who should still have a pencil stowed away
somewhere you can borrow to use for filling in the boxes.Here are the
February 1966,
April
1966, and June 1966 Electromaze Puzzles.
Electromaze Puzzle
 By Robert C. Radford
Here's a new kind of crossword puzzle designed to test your knowledge of electronic
terminology. Refer to the clues given and fill in the word called for by the first
clue. Start at the arrow. Thereafter, fill in each new word called for by the following
clues perpendicular to each preceding word. The last letter in each preceding word
will be common to the first or lost letter of each new word, and all words will
read vertically downward or from left to right. The tenth word will have a letter
in common with the word at the first exit. Nine more correct entries will take you
to the word at the second exit, which will also share a letter with the last of
these nine words. In each case, the first or last letter of the exit word will be
the first or last letter of the next word. An additional nine correct entries will
put you at the final exit for a perfect score. The Editors invite your comments
on this type of puzzle.
