Robert Radford's (not to
be confused with Robert Redford*) "Electromaze" is a unique - and weird - sort of
word puzzle format which first appeared in the April 1966 issue of Popular Electronics
magazine. Some people were 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. 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.

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 first or last letter in each preceding
word will be common to the first or last 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. A correct entry may or may not
fill up all of the white spaces available.
