Robert Radford's (not to be confused
with Robert Redford) "Electromaze" is a unique - and weird - sort of word puzzle that
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.

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.
