Pi Day 2008
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. |
Our Pi Day Sudoku puzzle is free to use and distribute. You can download the printable PDF version and use it however you see fit. 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 ! |
