Here's another unique puzzle. It was created by Brainfreeze Puzzles in honor of Pi Day (March 14, i.e. 3.14).

Quote:
What is Pi Day?

Pi Day is a celebration of the number π that occurs every March 14 (3.14...). Math geeks all over the world celebrate their math-geekiness on this day with pie-eating contests, recitations of the digits of pi, and occasionally fundraisers where math faculty get hit in the face with pies. At Brainfreeze Puzzles we celebrate Pi Day - how else? - with a Sudoku puzzle.

Rules: Each row, column, and jigsaw region must contain exactly the first twelve digits of pi, including repeats: 3.14159265358. Notice that each region will contain two 1's, two 3's, three 5's, and no 7's. This puzzle is the most fun you'll ever have memorizing the first twelve digits of π !

Perhaps a bigger challenge than solving this puzzle itself is the entering and then working at it in JSudoku. :ugeek:

BTW my gut feeling is that the 1st 12 digits of Pi should have been 3.14159265359 (rounded to 11 d.p.). :geek:

And thanks heaps for posting the other variants. To much to digest for now though. :study:

Well, I guess if you want to get really specific about the value of pi. . . :shock: :lol:

Well it says the first 12 digits of pi, not pi in twelve digits. If you write 123456789 and someone asks you, name the first 5 digits, you wouldn't say 12346 either. But that is just my opinion ;).

I also made puzzles based on the first digits of pi and i never rounded them either then. It's easier to find the digits this way for someone who doesn't know them by heart. Makes for interesting killers btw.

Nice graphics! I think the link I posted above has this one beat, though. . . ;)

More digits, aye, but does it have a catchy tune?

Ahhhh! I usually keep my speaker turned off, so I missed that. Thanks for the heads-up!

Is there a source of this? Or do you personally have a database of 1 billion Pi digits and just cranked it up yourself?

What is the earliest position for "0123456789", for example? :geek:
