April 1st is known as April Fools’ Day.
We could have chosen to celebrate a number of events that happened on this date. In the U.S. alone, it could have been the creation of the “$” symbol (1778), the marketing of the first dishwashing machine (1889), the first U.S. national women's swimming championships (1916), and many more. But instead, we choose to celebrate – pranks. Pranks have international appeal.
Since I am not a prankster, I will take this opportunity to lighten the tone of our blog with Sudoku. Sudoku has international appeal too but it is (usually) harmless.
So, I challenge you to Text-oku, a term I coined for Sudoku puzzles made up of letters. In each line (horizontal and vertical) and each 3x3 square, make sure you have the following nine letters: A, N, a, L, Y, T, I, C, S.
Click on each puzzle to enlarge it, then print and enjoy!
