Robert Radford's (not to be
confused with Robert Redford) "Electromaze" is a unique - and weird - sort of word puzzle
that appeared in the April 1966 issue of Popular Electronics magazine. 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. Note that
in my opinion the answer given for clue number 2 is technically wrong. What say you?

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 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 fast 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.
