Math Types
I laughed out loud when I read this one.
When watching the evening news today, I saw an image of coal barges lined up at the docks at the USS Mon Valley Steel Plant. Of course the news segment was about the White House blocking the sale of USS to Nippon Steel. My mind wandered to to dad's career at the Robena Prep Plant. I didn't think that it was still in operation but I searched for more information. I found that the Robena deep mines closed in 1983, but plant continued to operate until 2017 processing coal from surface mining for Consol Mining. It seems that reclamation of the site began many years before 2017, most likely mandated by local concerns about environmental damage from seepage from the three large slurry ponds and other surface contamination. Dad took me out one Sunday afternoon to inspect the dikes and berms around the ponds. We had to hop into one of the big company trucks to traverse the dirt roads around the site.

Ok, I guess I opened this door so I had to go and construct why this was funny.
What is Su Duko?
I've heard of it, but not being much of a game player, or a math type for that matter, I never looked it up or played.
Using WikiPedia
From a quick WikiPedia search I found that it's kind of like a crossword puzzle (maybe) but with numbers. (visit linkfor details and visuals)
The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each (that is, exclusively). The puzzle setter provides a partially completed grid.
The Joke
I guess the joke is that with only two digits (0,1) the game would be pretty easy. Kind of like "playing tennis with the net down". Or was that what Robert Frost had to say about writing free verse [1].

I tried to use Suduko puzzles in the classroom, but I don't usually do them. I like the crossword puzzle much better.
