3. SCI-DOKU
If you’re into sudoku, you might want to try a variation that appears weekly (free) on Scientific American’s Web site called SCI-DOKU [click here]. The puzzles use letters instead of numbers and, when completed, one row or column spells out an answer to a science-related clue.

I’ve been doing Sci-do-ku for a couple of months. They’re fun, some of my number-averse friends find them less daunting than regular sudoku…. (what is the plural?)
Fun!

Thanks, Charts. I remember Will Shortz once saying the plural of sudoku was sudoku.
