Take a break from the drudgery by trying your hand at some of these
goodies. Every word in the RF Cafe crossword puzzles is specifically related to
engineering, mathematics, and science. There are no generic backfill words like
many other puzzles give you, so you'll never see a clue asking for the name of a
movie star or a mountain on the Russia-China border.
All of these crossword puzzles
were created using the fabulous Crossword Express (now called "Magnum Opus") software.
